OQ2541HP General 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.
