FemtoClock® Crystal-to-LVCMOS/LVTTL ICS840022I-02 Clock Generator DATA SHEET General Description The ICS840022I-02 is a Gigabit Ethernet Clock Generator. The ICS840022I-02 uses a 25MHz crystal to synthesize 125MHz or 62.5MHz. The ICS840022I-02 has excellent phase jitter performance, over the 12kHz – 20MHz integration range. The ICS840022I-02 is packaged in a small 16-pin VFQFN, making it ideal for use in systems with limited board space. Features • One LVCMOS/LVTTL outputs, 20 output impedance • Crystal oscillator interface designed for 25MHz, 18pF parallel resonant crystal • Output frequencies: 125MHz or 62.5MHz • RMS phase jitter at 125MHz using a 25MHz crystal (12kHz - 20MHz): 0.57ps (typical) • Supply modes: Core/Output 3.3V/3.3V 3.3V/2.5V 2.5V/2.
