The ICS840021 is a Gigabit Ethernet Clock Generator and a member of the HiPerClocksTM HiPerClockS™ family of high performance devices from ICS. The ICS840021 uses a 25MHz crystal to synthesize 125MHz. The ICS840021 has excellent phase jitter performance, over the 1.875MHz – 20MHz integration range. .
• 1 LVCMOS/LVTTL output, 7Ω output impedence
• Crystal oscillator interface designed for 25MHz, 18pF parallel resonant crystal
• Output frequency: 125MHz
• VCO range: 560MHz to 680MHz
• RMS phase jitter @ 125MHz, using a 25MHz crystal (1.875MHz - 20MHz): 0.34ps (typical)
