PI6C490086 PLL Clock Multiplier Features Description ÎÎSupport XTAL or Clock input at 25MHz The PI6C490086 is a low jitter clock generator supporting either XTAL or reference input. Two of its buffered 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 25MHz with different power supplies and a 8.192 MHz clock signal. ÎÎThree buffered outputs support VDD operation ÎÎOne 8.192 MHz output ÎÎVery low phase jitter(RMS), 25MHz : < 2ps ÎÎVery low additive jitter: <500fs (typ) ÎÎ3.3V supply voltage for Core ÎÎ1.8V ~ 3.3V supply voltage for two outputs ÎÎPackaging: 16-pin TSSOP ÎÎCommercial & Industrial Temperature support Applications ÎÎNetworking Systems ÎÎFemtocell BTS ÎÎPeripheral Block Diagram Pin Configuration (16-Pin TSSOP) VDD VDDO PLL X1/CLKIN X2 Crystal Oscillator 1 16 X2 VDD 2 15 GND CLK8 GND 3 14 VDD 4 13 CLK3 VDD CLK1 VDDO8 5 12 CLK2 CLK2 CLK8 6 11 VDDO GND 7 10 CLK3 OE# 8 9 GND CLK1 GND 12-0165 X1/ICLKIN VDDO8 16-pin (173 mil) TSSOP OE# 1 www.pericom.com PI6C490086 RevB 2/16/2012 PI6C490086 PLL Clock Multiplier Pin number Pin Name Type Description 1 X1/CLKIN Input Crystal connection or clock input 2, 4, 14 VDD Power 3.3V Core and CLK1 supply voltage 5 VDDO8 Power Supply voltage for CLK8 6 CLK8 Output 8.192 MHz output 7, 9, 15 GND Power Connect to Ground 8 OE# Input Global output enable when low.
