PCS1P2859A
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
Voltage of 3.3V±5%V. The device is
available in a 16-pin TSSOP JEDEC package for
Industrial temperature range.
•
Zero ppm frequency synthesis error for all CLK outputs
•
Supply Voltage :3.3V ± 5%V
•
Low jitter design
•
Packaged in 16 pin TSSOP
•
Industrial Temperature range
•
Compatible with CY22393XC-F12
•
Advanced low-power CMOS process
Application
PCS1P2859A is targeted for use in high-end multimedia,
communications
and
consumer
applications.
