Texas Instruments LMK00804B-Q1 Automotive LVCMOS Fanout Buffers
Texas Instruments LMK00804B-Q1 Automotive LVCMOS Fanout Buffers and Level Translators can distribute up to four LVCMOS/LVTTL outputs (3.3V, 2.5V, 1.8V, or 1.5V levels) from one of two selectable inputs that can accept differential or single-ended inputs. The clock enable input is synchronized internally to eliminate runt or glitch pulses on the outputs when the clock enable terminal is asserted or de-asserted. Texas Instruments LMK00804B-Q1 fanout buffers feature outputs held in a logic low state when the clock is disabled. The LMK00804B-Q1 also allows the distribution of a low-jitter clock across four transceivers and can improve the overall target detection and resolution in a cascaded mmWave radar system.Features
