ZL30166数据手册集成电路（IC）的应用特定时钟/定时规格书PDF

描述 Description

The ZL30166 is a triple channel Clock Translator combining three programmable DPLLs / NCOs with four programmable precision synthesizers. Each channel accepts any frequency from 1kHz to 750MHz and generates any frequency from 1Hz to 750MHz to support any communication service over optical networks. For applications that require synchronizing to a 1PPS input, the ZL30166 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 ZL30166 operates from a single crystal resonator or clock oscillator supporting eight input references configurable as single ended or differential. It provides eight high performance LVPECL outputs and eight high performance LVCMOS outputs.
