PI6C490097 PLL Clock Multiplier Features Description ÎÎSupport XTAL or Clock input at 25MHz The PI6C490097 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 32kHz clock signal. ÎÎThree buffered outputs support VDD operation ÎÎOne 32.768 kHz output ÎÎVery low phase jitter(RMS), 25MHz : < 0.5ps ÎÎVery low additive jitter: <250fs (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 X2 Crystal Oscillator 16 X2 VDD 2 15 GND GND 3 14 VDD 4 13 CLK3 VDD CLK1 VDDO32 5 12 CLK2 CLK2 CLK32 6 11 VDDO GND 7 10 CLK3 OE# 8 9 GND CLK1 GND 12-0164 1 CLK32 PLL X1/CLKIN X1/ICLKIN VDDO32 16-pin (173 mil) TSSOP OE# 1 www.pericom.com PI6C490097 RevA 2/06/2012 PI6C490097 PLL Clock Multiplier Pin number Pin Name Type Description 1 X1/CLKIN Input Crystal connection or clock input 2, 4, 14 VDD Power Supply voltage 3.3V 5 VDDO32 Power Supply voltage for CLK32 6 CLK32 Output 32.768 kHz output 7, 9, 15 GND Power Connect to Ground 8 OE# Input Global output enable when low.
