Texas Instruments LMK1C110xA Asynchronous LVCMOS Clock Buffers
Texas Instruments LMK1C110xA Asynchronous LVCMOS Clock Buffers are modular, low-skew, high-performance, general-purpose clock buffers designed with a modular approach. Five different fan-out variations, 1:2, 1:3, 1:4, 1:6, and 1:8, are available. All of the devices within the family are pin-compatible with each other and backward compatible with the CDCLVC110x family for easy handling.
The Texas Instruments LMK1C110xA supports an asynchronous output enable control (1G) that switches the outputs into a low state when 1G is low. Asynchronous enable and disable are helpful for 1PPS applications and DC input operations. These have a fail-safe input that prevents oscillation at the outputs without an input signal and allows input signals before VDD is supplied.
