ESCRIPTION
The ICS840-77 is a SONET Oscillator Replace-
ment and a member of the HiPerClocks
TM
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.
