Overview
The CDCLVP1102RGTT from Texas Instruments is a highly versatile, low additive jitter buffer designed to generate two copies of LVPECL clock outputs from a single LVPECL, LVDS, or LVCMOS input. This device is particularly suited for various communication applications, offering a maximum clock frequency of up to 2 GHz. It is characterized by its low additive jitter performance of less than 100 fs RMS in the 10 kHz to 20 MHz offset range and an output skew as low as 10 ps, making it ideal for demanding applications.
