Multichannel clock distribution circuit

Features

■ 2, 3 or 4 output buffered clock distribution

■ Single-ended square wave (or sine wave) clock

input

■ Rail-to-rail (0 V to VTCXO) square wave output

■ Individual enable pin for each output

■ 1.8 V, high PSRR LDO for external clock

source voltage supply (VTCXO)

■ No AC coupling capacitor needed

■ Ultra-low phase noise and standby current

Flip Chip (12-bump, 16-bump)

■ Common system clock request, open drain,

active low

■ Clock enable signal polarities factory
