産品描述
産品描述
NCS23381 jitter attenuators / clock multiplier combines APLL and DPLL to deliver ultra-low jitter for high performance applications like wireless infrastructure. All PLL components are fully-integrated on-chip, eliminating the risk of noise coupling associated with discrete solutions. It features 4 differential or singleended 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.
NCS23381 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. NCS23381 is capable of generating any combination of output frequency from any input frequency as specified in the datasheet.
