Introduction
The SPI4 blocks provide dual 10 Gbits/s physical-to-link layer interfaces in conformance to the OIF-SPI4-02.0
specification. Each block provides a full-duplex interface with an aggregate bandwidth of 13.6 Gbits/s. This is
achieved by using 16 LVDS pairs each for RX and TX operating at a maximum data rate of 900 Mbits/s with a 450
MHz DDR clock. Both static and dynamic alignment are supported at the receive interface. Dynamic alignment is
used to compensate for bit-to-bit skew at higher data rates, where it becomes difficult to meet tight setup/hold
requirements. DIP-4 and DIP-2 parity generation and checking are supported. Data buffering of 8K bytes for both
transmit and receive is provided by embedded Dual-Port RAM in each SPI4 core. Internal 1K deep main and
shadow calendar supports scheduling of up to 256 ports. The Transmit and Receive Status FIFOs can also store
flow control information for up to 256 ports, the maximum specified in the SPI4 specification.
An independent QDRII Memory Controller block provides data buffering between the FPGA logic and external
memory and supports a throughput of greater than 20 Gbits/s. Data is transferred to and from memory through two
sets of 36-bit unidirectional data lines operating at up to 175 MHz DDR. A set of 72 data signals is available to
transfer data across the core-FPGA interface and allows the system to utilize the bandwidth available with second-
generation Quad Data Rate (QDRII) SRAMs. Of the 72 data signals, 8 signals can be either used for parity or data.
A soft IP version of this core is also available to allow a second data buffer on this device.
The High-Speed SERDES block supports four serial links, each operating at up to 3.7 Gbits/s (2.96 Gbits/s data
rate with 8b/10b encoding and decoding), to provide four full-duplex synchronous interfaces with built-in RX Clock
and Data Recovery (CDR) and transmitter preemphasis. The SERDES block is identical to that in the ORT82G5
FPSC, supports embedded 8b/10b encoding/decoding and implements link state machines for both 10G Ethernet,
and 1G/2G/10G Fibre Channel. The state machines are IEEE P802.3ae/D4.01 XAUI based and also support FC
(ANSI X3.230:1994) link synchronization.

The ORSPI4 device is offered in two packages: 1036 ftSBGA and 1156 fpBGA. The 1036 package offers 498 FPGA User I/Os while the 1156
ranges are derived from the following: Minimum System Gates assumes 100% of the PFU's are used for logic only (No PFU RAM) with 40%
EBR usage and 2 PLL's. Maximum System Gates assumes 80% of the PFU's are for logic, 20% are used for PFU RAM, with 80% EBR
usage and 4 PLL's.
package offers 356 FPGA User I/Os. Additionally, the SERDES option is not available on the 1156 package.
Internal performance of > 250 MHz
Over 16K programmable logic elements
1.5V operation (30% less power than 1.8 V operation)
Comprehensive I/O selections including LVTTL, LVCMOS, GTL, GTL+, PECL, SSTL3/2, HSTL, ZBT,
DDR, LVDS, bused-LVDS, and LVPECL
1036-pin ftSBGA package provides enough FPGA user I/Os (498) for 4 full-duplex XGMII interfaces, 4
full-duplex PL-3 interfaces, etc; a 40% smaller 1156-pin fpBGA package is available with 356 FPGA user
I/Os. Note: 1036-pin ftSBGA discontinued per PCN#06x-09.
