DESCRIPTION
The PL585 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 800MHz, 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 is designed to address the demanding
requirements of high performance applications such
as Fiber Channel, serial ATA, Ethernet, SAN,
SONET/SDH, etc.
