Integrated

Circuit

Systems, Inc.

FEMTOCLOCKS™ C RYSTAL-TO-LVPECL

312.5MHZ FREQUENCY MARGINING SYNTHESIZER

GENERAL DESCRIPTION

FEATURES

• One 312.5MHz nominal LVPECL output

The ICS843101I-312 is a low phase-noise

ICS

frequency margining synthesizer with fre-

quency margining capability and is a member of

the HiPerClockS™ family of high performance

clock solutions from ICS. In the default mode,

• Selectable crystal oscillator interface designed for 25MHz,

18pF parallel resonant crystal or LVCMOS/LVTTL

single-ended input

HiPerClockS™

• Output frequency can be varied in 2% steps from

nominal

the device nominally generates a 312.5MHz LVPECL output

clock signal from a 25MHz crystal input. There is also a

frequency margining mode available where the device can

be programmed, using the serial interface, to vary the

output frequency up or down from nominal in 2% steps.

The ICS843101I-312 is provided in a 16-pinTSSOP.

• VCO range: 560MHz - 690MHz

• RMS phase jitter @ 312.5MHz, using a 25MHz crystal

(1.875MHz - 20MHz): 0.52ps (typical)

• Output supply modes

Core/Output

3.3V/3.3V

2.5V/2.5V

• -40°C to 85°C ambient operating temperature

• Available in both standard and lead-free RoHS-complaint

packages
