ICS840022
FEMTOCLOCKSCRYSTAL-TO-
LVCMOS/LVTTL CLOCK GENERATOR
PRELIMINARY
GENERAL DESCRIPTION
The ICS840022 is a Gigabit Ethernet Clock
Generator and a member of the HiPerClocksTM
family of high performance devices from ICS.
The ICS840022 uses a 25MHz crystal to
synthesize 125MHz or 62.5MHz. The ICS840022
has excellent phase jitter performance, over the 1.875MHz –
20MHz integration range. The ICS840022 is packaged in a
small 8-pin TSSOP, making it ideal for use in systems with
limited board space.
FEATURES
1 LVCMOS/LVTTL output, 7 output impedence
Crystal oscillator interface designed for 25MHz,
18pF parallel resonant crystal
Output frequencies: 125MHz or 62.5MHz (selectable)
RMS phase jitter @ 125MHz, using a 25MHz crystal
(1.875MHz - 20MHz): 0.55ps (typical)
RMS phase noise at 125MHz:
Offset
Noise Power
100Hz .............. -106.3 dBc/Hz
1KHz .............. -126.3 dBc/Hz
10KHz .............. -131.7 dBc/Hz
100KHz .............. -130.8 dBc/Hz
3.3V operating supply
0°C to 70°C ambient operating temperature
