General Description
The APV2002 is a CMOS IC that integrates all circuit components required for a oscillator. It is a low
cost, low jitter, high performance oscillator, which
consists of low-current oscillator circuit and output
buffer. The IC also incorporates a high-precision, thinfilm feedback resistor and load capacitors with excellent frequency characteristics. It also offers frequency divider for application flexibility choice.
