open-in-new Find other Clock buffers

Description

The CDCLVC11xx is a modular, high-performance, low-skew, general-purpose clock buffer family from Texas Instruments.

The entire family is designed with a modular approach in mind. It is intended to round up TI’s series of LVCMOS clock generators.

Seven different fan-out variations, 1:2 to 1:12, are available. All of the devices are pin-compatible to each other for easy handling.

All family members share the same high performing characteristics such as low additive jitter, low skew, and wide operating temperature range.

The CDCLVC11xx supports an asynchronous output enable control (1G) which switches the outputs into a low state when 1G is low.

The CDCLVC11xx family operates in a 2.5-V and
3.3-V environment and are characterized for operation from –40°C to 85°C.
