Overview
The CDCLVC1103, part of the CDCLVC11xx family from Texas Instruments, is a high-performance, low-skew, general-purpose clock buffer. This device is designed with a modular approach, offering various fan-out options ranging from 1:2 to 1:12. The CDCLVC1103 is particularly suited for applications requiring low additive jitter and low output skew, making it ideal for general-purpose communication, industrial, and consumer applications. It operates within a supply voltage range of 2.5 V to 3.3 V and is characterized for operation from –40°C to 85°C.
