ORDERING INFORMATION TYPE NUMBER OQ2541BHP OQ2541BU PACKAGE NAME LQFP48 - DESCRIPTION
OQ2541BHP; OQ2541BU
DESCRIPTION The OQ2541B 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. The OQ2541B can be configured for use in STM1/OC3, STM4/OC12, STM16/OC48 and GE systems, with full ITU-T G.958 and G.813 jitter compliance, or Bellcore jitter compliance, whichever is applicable. The OQ2541B also features a bypass mode, for non SDH/SONET or GE bit rates, in which the clock recovery function is bypassed.
