ESCRIPTION
The ICS843-106 is a Fibre Channel Dual
Output Oscillator and a member of the
HiPerClockS™
HiPerClocks
TM
family of high perfor mance
devices from ICS. The ICS843-106 uses a
25MHz crystal to synthesize 106.25MHz.
The ICS843-106 has excellent jitter performance. The
ICS843-106 is packaged in a small 8-pin TSSOP,
making it ideal for use in systems with limited board space.
