Systems, Inc.

GENERAL DESCRIPTION

FEATURES

The ICS840-77 is a SONET Oscillator Replace- • One LVCMOS/LVTTL output, 15Ω output impedence

ICS

ment and a member of the HiPerClocks^TM

• Crystal oscillator interface designed for 19.44MHz,

family of high performance devices from ICS.

18pF parallel resonant crystal

HiPerClockS™

The ICS840-77 uses a 19.44MHz crystal to

synthesize 77.76MHz. The ICS840-77 has

• Output frequency: 77.76MHz

• Random jitter: 2.82ps (typical)

• Deterministic jitter: 0.205ps (typical)

• 3.3V operating supply

excellent jitter performance. The ICS840-77 is packaged in

a small 8-pin TSSOP, making it ideal for use in systems with

limited board space.

• 0°C to 70°C ambient operating temperature

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

packages
