PLL Clock Generator Single 8-Pin TSSOP

The CY2XP22 is a PLL (Phase Locked Loop) based high performance clock generator that uses an external reference crystal. It is specifically targeted at FibreChannel and Gigabit Ethernet applications. It produces a selectable output frequency that is 2.5 or 5 times the crystal frequency. With a 25 MHz crystal, the user can select either a 62.5 MHz or 125 MHz output. It uses Cypress’s low noise VCO technology to achieve less than 1 ps typical RMS phase jitter. The CY2XP22 has a crystal oscillator interface input and one LVPECL output pair.

• One LVPECL output pair
• Selectable frequency multiplication: × 2.5 or × 5
• External crystal frequency: 25.0 MHz
• Output frequency: 62.5 MHz or 125 MHz
• Low RMS phase jitter at 125 MHz, using 25 MHz crystal (1.875 MHz to 20 MHz): 0.4 ps (typical)
• Phase noise at 125 MHz (typical): Offset - Noise Power 1 kHz - 117 dBc/Hz 10 kHz - 126 dBc/Hz 100 kHz - 131 dBc/Hz 1 MHz - 131 dBc/Hz
• Pb-free 8-pin TSSOP package
• Supply voltage: 3.3 V or 2.5 V
• Commercial and Industrial temperature range
