EP4CGX75DF27C8 Overview
A Cyclone IV GX FPGA is a low-power, high-volume programmable logic device optimized for applications that require both parallel logic and multi-gigabit transceivers. The Cyclone IV GX family sits within the broader FPGA (Field Programmable Gate Array) -> programmable logic -> integrated circuit -> semiconductor taxonomy, and is differentiated from the non-transceiver Cyclone IV E family by its integrated multi-gigabit transceivers (MGTs).
Key features include 73,920 logic elements, 4,257,792 embedded memory bits, 274 embedded 18x18 multipliers, 310 user I/O pins, eight integrated 3.125 Gbps transceivers, and a 1.2 V core supply. The device supports DDR/DDR2/QDRII+ external memory interfaces and offers up to 4 PLLs. Operating junction temperature range is 0C to +85C (commercial grade, "C8" speed grade).
The Cyclone IV GX architecture combines a logic fabric of LABs (Logic Array Blocks) and MLABs (Memory Logic Array Blocks) with high-speed transceiver blocks, hard PCI Express Gen1 IP blocks, and a rich DSP block population. The 60 nm process delivers low static and dynamic power, while the integrated transceivers remove the need for external PHY chips in many serial protocols.
Typical applications include industrial video broadcast equipment, video surveillance and machine vision, industrial protocol bridging (PROFIBUS, PROFIBUS, EtherCAT), software-defined radio, low-cost ASIC prototyping, and embedded industrial control. The wide temperature-grade options and integrated transceivers make it well-suited for both commercial and industrial designs.
When designing with the EP4CGX75DF27C8, ensure proper decoupling (100 uF + 1 uF + 0.1 uF per the Cyclone IV pin connection guidelines) and follow the recommended PCB stackup for BGA fan-out. The integrated transceivers require careful PCB layout; reference the Cyclone IV GX Transceiver User Guide for channel loss budgeting and AC-coupling capacitor placement.

Typical Applications
EP4CGX75DF27C8 is suitable for 6 applications: Industrial Video Broadcast, Machine Vision Systems, Industrial Protocol Bridging, Software-Defined Radio Front-End, Low-Cost ASIC Prototyping, Surveillance and Security DVR.
Industrial Video Broadcast
The EP4CGX75DF27C8 fits industrial video broadcast by combining 73,920 logic elements with eight 3.125 Gbps transceivers that handle SDI/HDMI-over-serial links. The 4,257,792 embedded memory bits buffer video frames while 274 18x18 multipliers support real-time scaling and color-space conversion. Commercial 0-85C operation suits controlled-environment broadcast studios. Designers use the FPGA's hard PCIe Gen1 block to interface with host PCs for ingest cards, while LVDS pairs feed parallel camera/HDMI bridges.
Recommended
Machine Vision Systems
The EP4CGX75DF27C8 serves machine vision pipelines where its 274 18x18 multipliers accelerate Sobel, Gaussian, and convolution kernels for edge detection. The 73,920 logic elements implement Camera Link HS deserialization, while 4 Mbits of embedded memory line-buffer image rows. The eight transceivers support CoaXPress or GigE Vision uplinks. Commercial temperature range suits factory-floor vision cells; the 672-FBGA's high pin count connects parallel image sensors at full MIPI-CSI bandwidth.
Recommended
Industrial Protocol Bridging
The EP4CGX75DF27C8 is well-suited for industrial protocol bridging between EtherCAT, PROFINET, PROFIBUS, and EtherNet/IP masters and slaves. The eight integrated transceivers provide the PHY connectivity for the master Ethernet link, while 73,920 logic elements implement the deterministic slave state machines. The 310 user I/O pins drive isolated RS-485 and SPI links to legacy fieldbus peripherals. Industrial OEMs choose this FPGA when standard silicon ASSPs lack a required combination of protocol stacks.
Recommended
Software-Defined Radio Front-End
The EP4CGX75DF27C8 supports SDR front-end designs where 3.125 Gbps transceivers digitize IF or directly sample RF front-ends, while 274 18x18 multipliers implement digital down/up-conversion and pulse-shaping FIRs. The 4 Mbits of embedded memory hold channelization coefficients, and the 73,920 logic elements implement the modem baseband. The hard PCIe Gen1 block streams I/Q data to a host x86 processor, making the FPGA ideal for laboratory and signal-intelligence prototypes.
Recommended
Low-Cost ASIC Prototyping
The EP4CGX75DF27C8 functions as a low-cost ASIC prototype platform for designs that target ~70K ASIC gates. The 73,920 logic elements plus 274 multipliers map RTL blocks 1:1 onto FPGA fabric, while eight transceivers and the hard PCIe block replicate the real SoC's IO perimeter. Engineers reuse the same Quartus project for both FPGA prototype and ASIC synthesis baselines, dramatically reducing pre-silicon verification cycles for cost-sensitive consumer and IoT ASICs.
Recommended
Surveillance and Security DVR
The EP4CGX75DF27C8 enables multi-channel surveillance DVR designs where 73,920 logic elements implement H.264/H.265 encode assist and 4 Mbits of embedded memory hold reference frames. Eight transceivers aggregate IP-camera streams over Gigabit Ethernet, while 310 user I/O pins drive SATA links to local storage arrays. Commercial 0-85C operation suits indoor NVR enclosures. The Cyclone IV GX's low static power keeps thermals manageable in fanless designs.

Key Differentiators
- Speed grade 8 offers best cost-vs-performance for non-timing-critical industrial designs (vs EP4CGX75DF27C6)
- F27 672-FBGA gives 310 user I/Os vs the 484-FBGA F23's lower I/O count (vs EP4CGX75CF23C8)
- Same-die compatibility across all four F27 speed grades preserves Quartus project reuse (vs EP4CGX110DF27C8 (higher density))
Design Notes
The Cyclone IV GX EP4CGX75 requires a 1.2 V core supply and dedicated 2.5 V/1.2 V/3.0 V PLL/transceiver auxiliary rails. Follow the Cyclone IV Pin Connection Guidelines for the recommended decoupling network: place 100 µF bulk + 1 µF + 0.1 µF ceramic capacitors near each supply pin, and provide a separate ferrite-isolated island for the transceiver (VCCH_GXB) supply. Designers must power-up VCCINT before VCCAUX to avoid latch-up.
The 672-FBGA package requires a controlled-impedance PCB stackup with matched 50 ohm single-ended and 100 ohm differential traces for transceiver channels. Use a microstrip or stripline layout with the reference plane one dielectric thickness below the top layer, and route high-speed differential pairs length-matched to within 5 mils. BGA fan-out should use a 4- or 6-layer stackup with via-in-pad recommended for the inner rows.
Estimated: based on eight 3.125 Gbps channels, each transceiver requires AC-coupling capacitors (typically 100 nF 0402 size) on the TX and RX serial data pairs. Place these caps within 200 mils of the FPGA ball, with ground vias stitching the return path adjacent to each AC cap. Route each differential pair on the top layer with continuous ground reference, avoiding signal splits across plane voids.
Do not populate the EP4CGX75CF23C8 package on a board laid out for the EP4CGX75DF27C8 - the F23 484-FBGA and F27 672-FBGA pinouts are NOT identical. Also note that only 6 of the 8 PLLs in this device are usable for general clocking; some are reserved for transceiver reference clocks. Always re-run Quartus fitter pin assignments when changing speed grades (C6 vs C7 vs C8) since I/O timing differs.
Compliance Information
