AS5203
Digitally controlled differential DCTCXO

The AS5203 is a temperature compensated crystal oscillator (TCXO) with a pair of differential output clocks between 10 MHz and 156.25 MHz. The AS5203 utilizes digital temperature sensing and frequency compensation technologies to provide a high precision, temperature stabilized clock with grade options from ±5 ppm to ±20 ppm. Its digitally controlled oscillator (DCO) mode supports glitchless frequency pulling range up to ±25 ppm.
