PI6C557-10
Network Clock Generator
Description
The PI6C557-10 is an integrated 100MHz differential and 33MHz
LVCMOS clock generator. It uses a 25MHz quartz crystal to provide
an input frequency reference. The high performance internal PLL
multiplier is a proven design that ships world-wide for PCI Express
applications.
The PI6C557-10 is available in a 16 lead 4.4 x 5.0mm TSSOP
package and is operated from a single 3.3V supply. Separate supply
pins are provided for analog core, 100MHz differential output,
and 33MHz LVCMOS output to adhere to lowest risk, best known
power supply partitioning practices.
