PI6C490098 1:3 CMOS Clock Buffer Features Description IISupport XTAL or Clock input The PI6C490098 is a low jitter clock buffer supporting either XTAL or reference input. Two of its outputs can support wide operating voltage from 1.8V to 3.3V. It is a cost effective way to generate multiple outputs for all kinds of applications that need multiple CMOS outputs with different power supplies. IIThree buffered outputs support VDD operation IIVery low phase jitter(RMS) : < 0.5ps IIVery low additive jitter: <300fs (typ) II3.3V supply voltage for Core II1.8V ~ 3.3V supply voltage for two outputs IIPackaging: 16-pin TSSOP IICommercial & Industrial Temperature support Applications IINetworking Systems IIFemtocell BTS IIPeripheral Block Diagram Pin Configuration (16-Pin TSSOP) VDD VDDO CLK3 CLK2 X1/CLKIN X2 Crystal Oscillator CLK1 GND OE# X1/ICLKIN 1 16 X2 VDD 2 15 GND GND 3 14 VDD VDD 4 13 CLK1 NC 5 12 CLK2 NC 6 11 VDDO GND 7 10 CLK3 OE# 8 9 GND 16-pin (173 mil) TSSOP 16-0010 1 www.pericom.com PI6C490098 RevB 1/14/2016 PI6C490098 1:3 25MHz Clock Buffer Pin number Pin Name Type Description 1 X1/CLKIN Input Crystal connection or clock input 2, 4, 14 VDD Power 3.3V Supply voltage for core and CLK1 5, 6, NC 7, 9, 15 GND Power Connect to Ground 8 OE# Input Global output enable when low.

For user guidelines, not tested.) Note: Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
