Overview
The CDCLVP1102RGTR, produced by 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 due to its high performance and low jitter characteristics. It operates at a maximum clock frequency of up to 2 GHz and is characterized by its very low additive jitter of less than 100 fs RMS in the 10 kHz to 20 MHz offset range. The CDCLVP1102 is available in a compact 3-mm × 3-mm QFN-16 package and supports an industrial temperature range of –40°C to 85°C.
