a large variety of errors into the transmit stream, such as framing pattern errors,

bit interleaved parity errors, and illegal pointers, which are useful for system

diagnostics and tester applications.

ATM cells are written to an internal four cell FIFO using a generic 16- or 8-bit

wide datapath interface. Idle/unassigned cells are automatically inserted when

the internal FIFO contains less than one cell. The S/UNI-PLUS provides

generation of the header check sequence and scrambles the payload of the ATM

cells. Each of these transmit ATM cell processing functions can be enabled or

bypassed.

No line rate clocks are required directly by the S/UNI-PLUS as it synthesizes the

transmit clock and recovers the receive clock using a 19.44 MHz or 6.48 MHz

reference clock. Optionally, receive clock recovery or transmit clock synthesis

may be bypassed.

The S/UNI-PLUS is configured, controlled and monitored via a generic 8-bit

microprocessor bus interface. The S/UNI-PLUS also provides a standard 5

signal IEEE 1149.1 JTAG test port for boundary scan board test purposes.

The S/UNI-PLUS is implemented in low power, +5 Volt, CMOS technology. It has

TTL and pseudo-ECL (PECL) compatible inputs and TTL/CMOS compatible

outputs and is packaged in a 208 pin PQFP package.
