ORDERING INFORMATION TYPE NUMBER OQ2541HP OQ2541U PACKAGE NAME LQFP48 - DESCRIPTION APPLICATIONS
OQ2541HP; OQ2541U
· Data and clock recovery in STM1/OC3, STM4/OC12 and STM16/OC48 transmission systems · Data and clock recovery in Gigabit Ethernet (GE) transmission systems. 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.
