DESCRIPTION
The PL585-28 is a Dual LC core monolithic IC clock,
capable of maintaining sub-picoseconds 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 PL585-28 is designed to address the demanding
requirements of high performance applications such
as Fiber Channel, serial ATA, Ethernet, SAN,
SONET/SDH, etc.
