1 Low phase noise Fundamental Quartz Crystal Oscillator IC GENERAL DESCRIPTION The NJU6222 series is a C-MOS quartz crystal oscillator IC (20MHz to 50MHz) realized very low phase noise. It is consisted of an oscillation amplifer, divider (f 0, f 0 /2), and 3-state output buffer. There are 2-type of pad location for Flip chip and Wire bonding that apply SMD s 2016-package and more miniature. The NJU6222 in low voltage operation features low phase noise, it is suitable for high quality Hi-Fi sound device, Communication device, and others by battery drive.

3 VIRSION DISCRIMINATION INTERNAL COMPONENTS PAD layout version of the NJU6222 series is determined by the version name in chip. Divide version of the NJU6222 series is determined by the internal fuse trimming. Laser-trimmed versions are identified externally by the combination of the version name marking (1) and the locations of trimmed fuses (2).

4 TERMINAL DESCRIPTION SYMBOL FUNCTION Oscillation and 3-state Output Buffer Control H or OPEN Output one frequency selected out of f 0 and f 0 /2 Note1) L Oscillation Stop and High impedance Output Quartz Crystal Connection terminals GND terminal ( =0V) Frequency Output terminal (3-State Output Buffer) Power Supply terminal =1.62 to 3.63V Note1) Refer to the line-up table. FUNCTIONAL DESCRIPTION Standby Function When Terminal is Low, the Terminal output is High impedance. Oscillator High(Open) Frequency output Normal operation Low High impedance Stop When not using Stand-by function, terminal is recommended to connect to. Built-in Variable Pull-up Resistance of terminal The built-in pull-up resistance value of Terminal changes in response to the input level. When is LOW level, the pull-up resistance value is large to reduce the current consumption by the resistance. When is open or connected to, the pull-up resistance value is small to decrease the input susceptibility to external noise. It works to prevent an unexpectedly stopping of the output by external noise. ABSOLUTE MAXIMUM RATINGS ( =0V, Ta=25 C) PARAMETER SYMBOL RATING UNIT Supply Voltage -0.6 to +6.0 V Input Voltage V IN -0.6 to +VDD+0.6 and 6.0V V Output Voltage V O -0.6 to +0.6 V Input Current I IN 10 ma Output Current I O 25 ma Operating Temperature Range Topr -40 to +125 C Storage Temperature Range Tstg -55 to +150 C Note2) If the LSI used condition above the absolute maximum ratings, the LSI may be destroyed. Use beyond the electric characteristics conditions will cause mal-function and poor reliability.
