Diodes Incorporated PI6CL1001 Low Voltage LVCMOS Clock Buffer

Diodes Inc. PI6CL1001 Low Voltage LVCMOS Clock Buffer is a low voltage, low-noise, non-inverting Low Voltage Complementary Metal-Oxide Semiconductor (LVCMOS) single-output clock buffer with level translation. The Diodes Inc. PI6CL1001 supports a 1.0V to 1.8V power supply. This clock buffer targets networking applications that require a low-voltage power supply, low jitter, and the capability to bridge the power supply mismatch between clock source and clock sink devices. The VDD_IN supply voltage defines the input clock level, and the VDD_OUT supply voltage defines the output clock level. The device is capable of translating clock levels from low-to-high or from high-to-low. Fail-safe input prevents oscillation at the output in the absence of an input signal and allows for input signals before the VDD is supplied.
