3 Description

The CDCBT1001 is a 1.2-V to 1.8-V clock buffer

and level translator. The VDD_IN pin supply voltage

defines the input LVCMOS clock level. The VDD_OUT

pin supply voltage defines the output LVCMOS clock

level. VDD_IN = 1.2 V ± 10. VDD_OUT = 1.8 V ±

10

The 12-kHz to 5-MHz additive RMS jitter at 24 MHz is

less than 0.8 ps.
