CDCE72010RGCT

十大输出高性能时钟同步器，抖动消除器和时钟经销商 Ten Output High Performance Clock Synchronizer, Jitter Cleaner, and Clock Distributor

The is a high-performance low phase noise/low skew Clock Synchronizer that synchronizes a VCXO Voltage Controlled Crystal Oscillator or VCO Voltage Controlled Oscillator frequency to one of two reference clocks. The clock path is fully programmable providing the user with a high degree of flexibility. The PLL loop bandwidth and damping factor can be adjusted to meet different system requirements. The CDCE72010 can lock to one of two reference clock inputs PRI_REF and SEC_REF and supports frequency hold-over mode for fail-safe and system redundancy. The outputs of the CDCE72010 are user definable and can be any combination of up to 10 LVPECL/LVDS outputs or up to 20 LVCMOS outputs. The built-in synchronization latches ensure that all outputs are synchronized for very low output skew. All device settings, including output signalling, divider value selection, input selection and many more, are programmable with the SPI 4-wire Serial Peripheral Interface.
