■ Complete PCIe protocol solution with embedded PCIe hard IP blocks that implement PHY-MAC layer, Data Link layer, and Transaction layer functionality

■ Programmable transmitter pre-emphasis and receiver equalization circuitry to compensate for frequency-dependent losses in the physical medium

■ Typical physical medium attachment (PMA) power consumption of 100 mW at 3.125 Gbps and 135 mW at 6.375 Gbps per channel

■ 72,600 to 813,050 equivalent LEs per device

■ 7,370 to 33,294 Kb of enhanced TriMatrix memory consisting of three RAM block sizes to implement true dual-port memory and FIFO buffers

■ High-speed digital signal processing (DSP) blocks configurable as 9 x 9-bit, 12 x 12-bit, 18 x 18-bit, and 36 x 36-bit full-precision multipliers at up to 600 MHz

■ Up to 16 global clocks (GCLK), 88 regional clocks (RCLK), and 132 periphery clocks (PCLK) per device

■ Programmable power technology that minimizes power while maximizing device performance

■ Up to 1,120 user I/O pins arranged in 24 modular I/O banks that support a wide range of single-ended and differential I/O standards

■ Support for high-speed external memory interfaces including DDR, DDR2, DDR3 SDRAM, RLDRAM II, QDR II, and QDR II+ SRAM on up to 24 modular I/O banks

■ High-speed LVDS I/O support with serializer/deserializer (SERDES), dynamic phase alignment (DPA), and soft-CDR circuitry at data rates up to 1.6 Gbps

■ Support for source-synchronous bus standards, including SGMII, GbE, SPI-4 Phase 2 (POS-PHY Level 4), SFI-4.1, XSBI, UTOPIA IV, NPSI, and CSIX-L1

■ Pinouts for Stratix IV E devices designed to allow migration of designs from Stratix III to Stratix IV E with minimal PCB impact

Stratix IV GT Devices

Stratix IV GT devices provide up to 48 CDR-based transceiver channels per device:

■ Thirty-two out of the 48 transceiver channels have dedicated PCS and PMA circuitry and support data rates between 600 Mbps and 11.3 Gbps

■ The remaining 16 transceiver channels have dedicated PMA-only circuitry and support data rates between 600 Mbps and 6.5 Gbps
