Microchip Technology, Inc. 1-Ch SyncE Network Synchronizer ZL30161

The ZL30161 is a single channel Network Synchronization Clock Translator combining a single DPLL / NCO with three programmable synthesizers. The device is a fully compliant SEC (G.813) and EEC (G.8262) flexible rate conversion DPLL. It is capable of accepting and generating any frequency from 1Hz to 750MHz on up to eleven input references and up to twelve output clocks.
