High precision, small chip size and low power consumption
Ideal for short distance wireless communication
~NPC releases CMOS IC “7101 series” for crystal oscillator module~

SEIKO NPC Corporation (HQ: Chuo-ku, Tokyo, President: Hiroaki Okawa) has released CMOS IC “7101 series” for crystal oscillator modules.


The 7101series is crystal oscillator module CMOS IC with both f0 adjustment function and frequency dividing function. The oscillator circuit stage has a voltage regulator drive, which reduces current consumption and frequency deviation due to fluctuations in the supply voltage. Even with those enhanced functions built in, its small chip size enables it to be implemented in a 1612 package.


  • High precision, small chip size suitable for short distance radio communication, and operable up to 125℃
  • High precision achieved by built-in f0 adjustment function
  • Various frequencies available via deviding function, that shortens your lead-time and reduces management costs
