Features, Applications

s General Description s Package Outline The 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 NJM2555C-C recommended input crystal frequency is from 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. s Features qOperating Voltage: to +3.6V qFrequency range of Crystal: 155.52 MHz typ. to 160 MHz) qOutput Frequency Range:622.08 MHz typ. to 640 MHz) qOutput Level: differential LVPECL equivalent qA Variable Capacitor on chip qBipolar Technology qPackage: Die s Terminal Description & Coordinates No. Symbol Function 1 VOSC OSC Supply Voltage 2 XT1 Quartz Crystal Connecting terminal 3 XT2 Quartz Crystal Connecting terminal 2 4 VVC Frequency Control 5 GND 6 FOUT1 Frequency Output 7 FOUT2 Frequency Output 8 T1 Tunable Filter Terminal 9 T2 Tunable Filter Terminal 2 10 VCC VCC=3.3V Starting Point: Die Center Chip Size: 1.60x2.00 [mm] Chip Thickness: 260 20 [um] Pad Size: 90x90 [um] s Block Diagram
