Functional Description
The Local Area Network ATM Transceiver is used in SO-
NET/SDH and ATM applications to recover clock and data in-
formation from a 155.52-MHz or 51.84-MHz NRZ or NRZI se-
rial data stream and to provide differential data buffering for the
Transmit side of the system.
SUNI is a trademark of PMC-Sierra, Incorporated.
