Description:

Altera’s new Cyclone® IV FPGA device family extends the Cyclone FPGA series leadership in providing the market’s lowest-cost, lowest-power FPGAs, now with a transceiver variant. Cyclone IV devices are targeted to high-volume, cost-sensitive applications, enabling system designers to meet increasing bandwidth requirements while lowering costs.Built on an optimized low-power process, the Cyclone IV device family offers the following two variants:

■ Cyclone IV E—lowest power, high functionality with the lowest cost

■ Cyclone IV GX—lowest power and lowest cost FPGAs with 3.125 Gbps 

The Cyclone IV device family offers the following features:

■ Low-cost, low-power FPGA fabric:

■ 6K to 150K logic elements

■ Up to 6.3 Mb of embedded memory

■ Up to 360 18 × 18 multipliers for DSP processing intensive applications

■ Protocol bridging applications for under 1.5 W total power

■ Cyclone IV GX devices offer up to eight high-speed transceivers that provide:

■ Data rates up to 3.125 Gbps

■ 8B/10B encoder/decoder

■ 8-bit or 10-bit physical media attachment (PMA) to physical coding sublayer (PCS) interface

■ Byte serializer/deserializer (SERDES)

■ Word aligner

■ Rate matching FIFO

■ TX bit slipper for Common Public Radio Interface (CPRI)

■ Electrical idle

■ Dynamic channel reconfiguration allowing you to change data rates and protocols on-the-fly

■ Static equalization and pre-emphasis for superior signal integrity

■ 150 mW per channel power consumption

■ Flexible clocking structure to support multiple protocols in a single transceiver block

■ Cyclone IV GX devices offer dedicated hard IP for PCI Express (PIPE) (PCIe) Gen 1:

■ ×1, ×2, and ×4 lane configurations

■ End-point and root-port configurations

■ Up to 256-byte payload

■ One virtual channel

■ 2 KB retry buffer

■ 4 KB receiver (Rx) buffer

■ Cyclone IV GX devices offer a wide range of protocol support:

■ PCIe (PIPE) Gen 1 ×1, ×2, and ×4 (2.5 Gbps)

■ Gigabit Ethernet (1.25 Gbps)

■ CPRI (up to 3.072 Gbps)

■ XAUI (3.125 Gbps)

■ Triple rate serial digital interface (SDI) (up to 2.97 Gbps)

■ Serial RapidIO (3.125 Gbps)

■ Basic mode (up to 3.125 Gbps)

■ V-by-One (up to 3.0 Gbps)

■ DisplayPort (2.7 Gbps)

■ Serial Advanced Technology Attachment (SATA) (up to 3.0 Gbps)

■ OBSAI (up to 3.072 Gbps)
