DESCRIPTION
The OQ2541 is a data and clock recovery IC intended for
use in Synchronous Digital Hierarchy (SDH) and
Synchronous Optical Network (SONET) systems.
The circuit recovers data and extracts the clock signal
from an incoming bitstream up to 2.5 Gbits/s. It can be
configured for use in STM1/OC3, STM4/OC12,
STM16/OC48 and Gigabit Ethernet systems.
