NJM2555 622MHz VCXO ICThe NJM2555 is a 622.08MHz VCXO (Voltage Controlled Crystal Oscillator) IC designed for optical fiber telecommunication systemsusing NewJRC superior Bipolar technologywhich consists of an oscillation amplifiera variable capacitor diodea quadruple (4) frequency circuithigh pass filterand limiter Amplifier The NJM2555 generate x4 frequency to add the only 155.52MHz crystal and LC filterand the output is differential LVPECL equivalent. The recommended input crystal frequency is from 120 to 160 MHz. The jitter performance and phase noise is very low based on excellent oscillation circuit. This CAN be applied to optical communicationespecially the WDM system.
