EP4CGX30CF19C8N Overview
A Field-Programmable Gate Array (FPGA) is a programmable logic device that lets designers implement arbitrary digital logic, memory blocks, and high-speed serial interfaces after PCB fabrication. FPGAs sit in the programmable-logic branch of the digital-semiconductor hierarchy: ASIC < structured ASIC < CPLD < FPGA. Cyclone IV GX specifically targets cost-sensitive applications that still require embedded transceivers, embedded PCIe Gen1 hard IP, and moderate logic density, bridging the gap between pure CPLDs and high-end Stratix-class FPGAs.
The Cyclone IV GX family is differentiated from the Cyclone IV E family by the inclusion of up to eight 3.125 Gbps multi-gigabit transceivers and two PCIe hard IP blocks. The EP4CGX30 variant provides four full-duplex transceiver channels at up to 3.125 Gbps. The transceiver PMA block supports multiple serial protocols including PCIe Gen1, Gigabit Ethernet, Serial RapidIO, CPRI, and basic SDI/HD-SDI video transport, while the embedded PCIe hard IP supports x1 and x2 Endpoint and Root Port configurations.
Typical applications include industrial video-broadcast bridges (SDI/HD-SDI to HDMI/DisplayPort conversion), machine-vision frame grabbers using PCIe Gen1, low-cost protocol-bridging cards (Serial RapidIO or GbE to local bus), low-density wireline aggregation backplanes, and consumer electronics requiring custom video processing pipelines with a small FPGA footprint. The 1.0 mm pitch FBGA-324 supports conventional 4-layer PCB designs with via-in-pad recommended for transceiver breakouts.
When designing with this part, follow Altera's Cyclone IV GX transceiver-layout guidelines: keep AC-coupling capacitors within 200 mil of the transceiver ball, route TX/RX pairs with 100 ohm differential impedance, and isolate transceiver power (VCCRT, VCCT_GXB) from digital core (VCCINT) planes. Configure the on-chip PCIe hard IP with Quartus II 13.0sp1 or later (the last Quartus release supporting Cyclone IV GX is 13.0sp1/13.1).

Typical Applications
EP4CGX30CF19C8N is suitable for 7 applications: Industrial Video-Broadcast Bridges (SDI/HD-SDI to HDMI/DisplayPort), Machine-Vision Frame Grabbers with PCIe Gen1 Interface, Protocol-Bridging Cards (Serial RapidIO / GbE to Local Bus), Low-Density Wireline Backplane Aggregation, Custom Video-Processing Pipelines for Consumer Electronics, Industrial Control and Motor-Drive Auxiliary Logic, Test & Measurement Front-End Digitizer Aggregation.
Industrial Video-Broadcast Bridges (SDI/HD-SDI to HDMI/DisplayPort)
The EP4CGX30CF19C8N fits industrial video bridge applications because its 4 transceivers at up to 3.125 Gbps comfortably carry HD-SDI (1.485 Gbps) and 3G-SDI (2.97 Gbps) serial video streams with margin, while the embedded PCIe hard IP is unused for this use case. The 29,440 logic elements and 66 18x18 multipliers are sufficient for color-space conversion, scaling, frame-rate conversion, and HDCP-style overlay processing. The 150 user I/O pins accommodate parallel video buses (TTL/CMOS or LVDS) plus I2C, SPI, and GPIO for display configuration. The commercial 0-85 C temperature range covers broadcast-equipment rack environments.
Recommended
Machine-Vision Frame Grabbers with PCIe Gen1 Interface
The EP4CGX30CF19C8N integrates two PCIe Gen1 hard IP blocks, enabling direct x1 or x2 PCIe connectivity to a host PC without consuming fabric resources for a soft PHY. Combined with 4 transceivers, the part can simultaneously receive Camera Link or CoaXPress-over-fiber sensor data and forward pre-processed frames to the host via PCIe. The 1,105,920 bits of embedded RAM provide line buffers for image preprocessing (tap balancing, gamma correction). The 1.2 V core supply and commercial temperature range suit PCI-card industrial PC form factors with chassis airflow.
Recommended
Protocol-Bridging Cards (Serial RapidIO / GbE to Local Bus)
With its 4 transceivers supporting Serial RapidIO, Gigabit Ethernet, and basic CPRI protocols, the EP4CGX30CF19C8N is well-suited to low-cost protocol-bridging cards that aggregate wireline traffic and present it over a parallel local bus to an ASSP or microcontroller. The 4 PLLs provide independent clock domains for the upstream serial interface and the downstream parallel bus. The 29,440 logic elements handle packet parsing, header stripping, and DMA descriptor generation. Industrial 0-85 C operation matches telecom and factory-floor enclosure environments.
Recommended
Low-Density Wireline Backplane Aggregation
The EP4CGX30CF19C8N's transceiver count of 4 channels at 3.125 Gbps is sufficient for small form-factor pluggable (SFP) backplane aggregation in central-office or wireless-backhaul line cards where the FPGA aggregates multiple lower-rate serial links into a higher-rate uplink. The embedded PCIe hard IP supports in-band management via the host CPU. The 66 embedded 18x18 multipliers enable FEC acceleration. The 19x19 mm 1.0 mm pitch FBGA footprint fits standard line-card PCB real estate and supports via-in-pad manufacturing for backplane connector breakouts.
Recommended
Custom Video-Processing Pipelines for Consumer Electronics
For consumer electronics requiring custom video-processing (3D-comb filtering, deinterlacing, picture-in-picture, HDMI-side data injection), the EP4CGX30CF19C8N provides the optimal balance of 29,440 logic elements and 66 18x18 multipliers without the cost of a higher-end Cyclone V or Stratix-class FPGA. The 150 user I/O pins handle multi-channel parallel RGB/YUV input plus HDMI/DisplayPort side-band signals. The 4 transceivers accept SDI or HDMI-over-twisted-pair inputs. Commercial 0-85 C operation covers set-top-box and television chassis thermal profiles.
Recommended
Industrial Control and Motor-Drive Auxiliary Logic
In factory automation, the EP4CGX30CF19C8N can serve as auxiliary glue logic on a motor-drive controller board: implementing quadrature encoder interfaces, CANopen/EtherCAT-slave glue logic (when paired with an external PHY), safety-watchdog timers, and fieldbus-protocol conversion (Modbus, PROFIBUS) to higher-speed Industrial Ethernet uplinks via the transceivers. The 66 embedded multipliers support field-oriented control (FOC) preprocessing for adjacent microcontrollers. The 0-85 C commercial temperature range plus RoHS lead-free finish meets modern industrial compliance requirements.
Recommended
Test & Measurement Front-End Digitizer Aggregation
The EP4CGX30CF19C8N can aggregate multiple lower-speed ADC lanes (LVDS parallel) into a single high-speed serial link for transmission to a back-end processor board. The 4 transceivers, 150 user I/O pins, and 66 multipliers support simultaneous capture of 8-16 LVDS lanes at up to 1 Gbps each. The PCIe hard IP enables direct insertion into a PXI or CompactPCI backplane. Commercial 0-85 C operation and lead-free FBGA-324 make the part compatible with laboratory and production-floor test instrumentation enclosures.

- Stepping-down option for lower-density designs (vs EP4CGX22CF19C8N)
Design Notes
Follow Altera's Cyclone IV GX transceiver-layout guidelines for the EP4CGX30CF19C8N: place AC-coupling capacitors within 200 mil of the GXB ball pairs, route TX/RX pairs with 100 ohm differential impedance, and isolate VCCT_GXB and VCCR_GXB power planes from the VCCINT digital core plane. Use via-in-pad construction with 0.6 mm drilled pads for transceiver breakouts to maintain signal integrity up to 3.125 Gbps.
The EP4CGX30CF19C8N requires five separate power rails: VCCINT (1.16-1.24 V core), VCCIO (per-bank 1.2/1.5/1.8/2.5/3.3 V), VCCA_PLL (2.5 V analog PLL), VCCT_GXB and VCCR_GXB (1.2 V transceiver TX/RX). Per the Cyclone IV GX handbook, these rails must be sequenced so VCCINT ramps before VCCIO. Use a multi-rail sequencer such as the LM3880 or UCD90120A. Estimate: at typical utilization (50% LEs, 50% RAM, all 4 transceivers at 3.125 Gbps) the part consumes approximately 2.5-3.0 W.
Quartus Prime does NOT support Cyclone IV GX - use legacy Quartus II 13.0sp1 or 13.1 (the last official releases). Programming files generated by newer Quartus Prime cannot target this part. Also, the EP4CGX30CF19C8N uses 1.8 V configuration flash (EPCS16 or EPCS64) - do not substitute 3.3 V EPCS parts. For JTAG, use a 10-pin 0.05-inch-pitch header per Altera's ByteBlaster II specification.
Estimated: at typical 3 W consumption and the FBGA-324 package's theta_JA of approximately 22 C/W (with 4-layer JEDEC test board, no airflow), junction temperature rise above ambient is approximately 66 C. This places Tj around 116 C at 50 C ambient - close to the 125 C commercial max. Provide at least 200 LFM of forced-air cooling for industrial chassis above 60 C ambient, or upgrade to the industrial-temperature variant EP4CGX30CF19I7N.
Compliance Information
