ORT42G5-2BM484I FPGAs Overview
The ORT42G5-2BM484I and ORT82G5 provide a clockless high-speed interface for interdevice communication on a board or across a backplane. The built-in clock recovery of the ORT42G5-2BM484I and ORT82G5 allows for higher system performance, easier-to-design clock domains in a multiboard system, and fewer signals on the backplane. Network designers will benefifit from the backplane transceiver as a network termination device. The device supports embedded 8b/10b encoding/decoding and link state machines for 10 G Ethernet, and Fibre Channel.
The ORT82G5 is pinout compatible with a sister device, the ORSO82G5, which implements eight channels of SERDES with SONET scrambling and cell processing. The ORT42G5-2BM484I is pin compatible with the ORSO42G5,which implements four channels of SERDES with SONET scrambling and cell processing.

Features
• High-performance programmable logic:
– 0.16 µm 7-level metal technology.
– Internal performance of >250 MHz.
– Over 400K usable system gates.
– Meets multiple I/O interface standards.
– 1.5V operation (30% less power than 1.8V operation) translates to greater performance.
• Traditional I/O selections:
– LVTTL (3.3V) and LVCMOS (2.5V and 1.8V) I/Os.
– Per pin-selectable I/O clamping diodes provide 3.3V PCI compliance.
– Individually programmable drive capability: 24 mA sink/12 mA source, 12 mA sink/6 mA source, or 6 mA
sink/3 mA source.
– Two slew rates supported (fast and slew-limited).
– Fast-capture input latch and input Flip-Flop (FF)/latch for reduced input setup time and zero hold time.
– Fast open-drain drive capability.
– Capability to register 3-state enable signal.
– Off-chip clock drive capability.
– Two-input function generator in output path
• New programmable high-speed I/O:
– Single-ended: GTL, GTL+, PECL, SSTL3/2 (class I and II), HSTL (Class I, III, IV), ZBT, and DDR.
– Double-ended: LVDS, bused-LVDS, and LVPECL. Programmable (on/off) internal parallel termination (100
Ω) is also supported for these I/Os.
• New capability to (de)multiplex I/O signals:
– New DDR on both input and output at rates up to 350 MHz (700 MHz effective rate).
– New 2x and 4x downlink and uplink capability per I/O (i.e., 50 MHz internal to 200 MHz I/O).
• Enhanced twin-block Programmable Function Unit (PFU):
– Eight 16-bit Look-Up Tables (LUTs) per PFU.
– Nine user registers per PFU, one following each LUT, and organized to allow two nibbles to act independently, plus one extra for arithmetic operations.
– New register control in each PFU has two independent programmable clocks, clock enables, local SET/RESET, and data selects.
– New LUT structure allows flflexible combinations of LUT4, LUT5, new LUT6, 4 → 1 MUX, new 8 → 1 MUX, and ripple mode arithmetic functions in the same PFU.
– 32 x 4 RAM per PFU, confifigurable as single- or dual-port. Create large, fast RAM/ROM blocks (128 x 8 in only eight PFUs) using the Supplemental Logic and Interconnect Cell (SLIC) decoders as bank drivers.
– Soft-Wired LUTs (SWL) allow fast cascading of up to three levels of LUT logic in a single PFU through fast internal routing which reduces routing congestion and improves speed.
– Flexible fast access to PFU inputs from routing.
– Fast-carry logic and routing to all four adjacent PFUs for nibble-wide, byte-wide, or longer arithmetic functions, with the option to register the PFU carry-out.
