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.
