LMK00334/38/Q1 Clock Buffer/Level Translators

Texas Instruments LMK00334/38/Q1 Clock Buffer/Level Translator is intended for high-frequency, low-jitter clock/data distribution and level translation. The input clock can be selected from two universal inputs or one crystal input. The selected input clock is distributed to two banks of 2 HCSL (4 HCSL LMK00338) outputs and one LVCMOS output. The LVCMOS output has a synchronous enable input for runt-pulse-free operation when enabled or disabled. The LMK00334/38 operates from a 3.3 V core supply and 3 independent 3.3 V/2.5 V output supplies. The LMK00334/38/Q1 provides high performance, versatility, and power efficiency, making it ideal for replacing fixed-output buffer devices while increasing timing margin in the system. The LMK00334/38-Q1 devices are AEC-Q100 qualified for automotive applications.
