Integrated

Circuit

Systems, Inc.

FEMTOCLOCKS™ C RYSTAL-TO-LVDS

312.5MHZ FREQUENCY MARGINING SYNTHESIZER

GENERAL DESCRIPTION

FEATURES

• One 312.5MHz nominal LVDS output

The ICS844101I-312 is a low phase-noise

ICS

frequency margining synthesizer and is a mem-

ber of the HiPerClockS™ family of high perfor-

mance clock solutions from ICS. In the default

mode, the device nominally generates a

• Selectable crystal oscillator interface designed for 25MHz,

18pF parallel resonant crystal or LVCMOS single-ended

input

HiPerClockS™

312.5MHz LVDS output clock signal from a 25MHz crystal • Output frequency can be varied in 2% steps from nominal

input. There is also a frequency margining mode available

where the device can be programmed, using the serial in-

• VCO range: 560MHz - 690MHz

terface, to vary the output frequency up or down from nomi-

nal in 2% steps. The ICS844101I-312 is provided in a 16-

pin TSSOP.

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

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

• Output supply modes

Core/Output

3.3V/3.3V

3.3V/2.5V

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

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

packages
