ORT8850 Overview
The ORT8850 FPSCs provide high-speed backplane transceivers combined with FPGA logic. There are two
devices in the ORT8850 family. The ORT8850L device is based on 1.5 V OR4E02 ORCA FPGA and has a 26 x 24
array of Programmable Logic Cells (PLCs). The ORT8850H device is based on 1.5V OR4E06 ORCA FPGA and
has a 46 x 44 array. The embedded core which contains the backplane transceivers is attached to the right side of
the device and is integrated directly into the FPGA array. A top level diagram of the basic chip conguration is
shown in Figure 1.

Embedded Core Overview
The ORT8850 embedded core contains a pseudo-SONET block for backplane or intra-board, chip-to-chip commu-
nication. The SONET block includes a High-Speed Interface (HSI) macrocell and a Synchronous Transport Module
(STM) macrocell. It supports eight full-duplex channels and performs data transfer, scrambling/descrambling and
SONET framing at the maximum rate of 850 Mbits/s. Figure 2 shows a top level diagram of the ORT8850 and the
basic data ows through the device.
