PM5350 S/UNI-ULTRA
SATURN USER NETWORK INTERFACE
No line rate clocks are required directly by the S/UNI-ULTRA as it synthesizes
the transmit clock and recovers the receive clock using a 19.44 MHz reference
clock.
The S/UNI-ULTRA provides output control signals that can be used to command
an LED display, making it easy to visually monitor either alarms, or the transmit
and receive activity.
The S/UNI-ULTRA is configured, controlled and monitored via a generic 8-bit
microprocessor bus interface. It is implemented in low power, +5 Volt CMOS
technology. It has TTL and pseudo-ECL (PECL) compatible inputs and outputs
and is packaged in a 128 pin PQFP package.
