Digital controlled differential silicon oscillator

The AS5003 silicon oscillator utilizes proprietary frequency synthesis and sensor technologies to provide a quartz-free, MEMS-free, clock with a typical phase jitter of 350 fs that supports frequencies between 0.01 and 350 MHz with programmable universal differential driver format. It supports programmability of frequency by 0.026ppb resolution and all output formats thourgh I2C interface.
