622MHz VCXO IC
I
GENERAL DESCRIPTION
The NJM2555 is a 622.08MHz VCXO (Voltage Controlled Crystal
Oscillator) IC designed for optical fiber telecommunication systems, using
NewJRC superior Bipolar technology, which consists of an oscillation
amplifier, a variable capacitor diode, a quadruple (x4) frequency circuit, high
pass filter, and limiter amplifier. The NJM2555 generate x4 frequency to add
the only 155.52MHz crystal and LC filter, and 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 communication,
especially the WDM system.
