Texas Instruments LMK1C1106/LMK1C1108 LVCMOS Clock Buffers
Texas Instruments LMK1C1106/LMK1C1108 LVCMOS Clock Buffers are a modular, high-performance, low-skew, general-purpose clock buffer family. The entire family is 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 this family are pin-compatible with each other and backward compatible with the CDCLVC110x family for easy handling. All family members share the same high-performing characteristics, such as low additive jitter, low skew, and a wide operating temperature range.
The Texas Instruments LMK1C1106/LMK1C1108 supports a synchronous output enable control (1G), which switches the outputs into a low state when 1G is low. The LMK1C1106/LMK1C1108 operates in a 1.8V, 2.5V, and 3.3V environment and is characterized for operation from -40 °C to +125 °C.
