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 components.
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.
