Product Description
The PCS1P2859A is a Precision multi-PLL based
frequency synthesizer. The six Clock outputs are
generated using an inexpensive 25MHz Crystal. The
outputs consist of 25 MHz reference clock, 33 MHz, two
127MHz and two 48MHz clocks. The SHUTDOWNB tri-
states all the clocks when enabled. The device operates
from a Supply
available in a 16-pin TSSOP JEDEC package for
Industrial temperature range.
Application
