General Description

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 ponents.

The high performance and high frequency output is achieved using a low cost fundamental crystal of between 19MHz and 40 MHz.

The PL685-28 is designed to address the demanding requirements of high performance applications such as Fiber Channel, serial ATA, Ethernet, SAN, SONET/SDH, etc.

Key Features
