The ZL30167 is a dual channel Clock Translator combining two programmable DPLLs / NCOs with four programmable synthesizers to support any communication service over optical networks. For applications that require synchronizing to a 1PPS input, the ZL30167 supports a sync pulse/clock pair feature. Any of the inputs can be used for a 1PPS signal shared with any other input for a reference frequency. The output will be synchronized to the input reference and will be phase aligned to the 1PPS input. This unique feature allows a line card with a crystal to be used for synchronizing to a 1PPS input. This normally requires a PLL with a 30mHz bandwidth and TCXO. With very low power consumption, the ZL30167 operates from a single crystal resonator or clock oscillator. It is capable of accepting any frequency from 1kHz to 750MHz on up to eleven input references and generating any frequency from 1Hz to 750MHz on up to sixteen output clocks.
