ICS844051I

FEMTOCLOCKS™ CRYSTAL-TO- LVDS

CLOCK GENERATOR

PRELIMINARY

GENERAL DESCRIPTION

The ICS844051I is a Gigabit Ethernet Clock

Generator and a member of the HiPerClocksTM

family of high performance devices from ICS.

The ICS844051I can synthesize 10 Gigabit

Ethernet, SONET, or Serial ATA reference clock

frequencies with the appropriate choice of crystal and output

divider. The ICS844051I has excellent phase jitter perfor-

mance and is packaged in a small 8-pin TSSOP, making it

ideal for use in systems with limited board space.

FEATURES

• One Differential LVDS output

• Crystal oscillator interface designed for

18pF parallel resonant crystals (18.125MHz - 23.4375MHz)

• Output frequency range: 145MHz - 187.5MHz and

72.5MHz - 93.75MHz

• VCO range: 580MHz - 750MHz

• RMS phase jitter @156.25MHz (1.875MHz - 20MHz):

0.45ps (typical)

• 3.3V or 2.5V operating supply

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

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