ICS840-77
77.76MHZ, LVCMOS/LVTTL
OSCILLATOR REPLACEMENT
GENERAL DESCRIPTION
The ICS840-77 is a SONET Oscillator Replace-
ment and a member of the HiPerClocksTM
family of high performance devices from ICS.
The ICS840-77 uses a 19.44MHz crystal to
synthesize 77.76MHz. The ICS840-77 has
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.
FEATURES
One LVCMOS/LVTTL output, 15Ω output impedence
Crystal oscillator interface designed for 19.44MHz,
18pF parallel resonant crystal
Output frequency: 77.76MHz
Random jitter: 3ps (typical)
Deterministic jitter: 0.125ps (typical)
3.3V operating supply
0°C to 70°C ambient operating temperature
Available in both standard and lead-free RoHS-compliant
packages
