PL685-28 19MHz to 250MHz Low Phase-Noise XO

The PL685-28 is a Dual LC core monolithic IC clock, capable of maintaining sub-1ps RMS phase jitter, while covering a wide frequency output range up to 250MHz, without the use of external components. The high performance and high frequency output is achieved using a low cost fundamental crystal of b.
