描述 Description

NCS233C5 is a programmable loop bandwidth Network Synchronization PLL that provides jitter attenuator function and synchronization clock function for many systems. All PLL components are fully integrated on-chip, eliminating the risk of noise coupling associated with discrete solutions. It features 5 differential or single-ended clock inputs and 12 differential or 24 single-ended clock outputs. Furthermore, 4 independent APLL/ DPLL outputs can be locked to any of the inputs and sent to any of the chip outputs. Each output can be configured as LVDS, LVPECL or two single-ended LVCMOS. In addition, each output clock phase can be adjusted dynamically. NCS233C5 supports free-run, synchronous and holdover modes as well as enhanced automatic or manual hitless switching between input clocks. It is programmable by I2C or SPI serial interface. NCS233C5 is capable of generating any combination of output frequency from any input frequency as specified in the datasheet.
