Multi-Output Clock Synthesizer
Features
Product Description
• Generates multiple clock outputs from an inexpensive
The PCS1P2859A is a Precision multi-PLL based
frequency synthesizer. The six Clock outputs are
25MHz crystal or external reference clock
• Frequency outputs:
generated using an inexpensive 25MHz Crystal. The
•
25MHz Reference clock
outputs consist of 25 MHz reference clock, 33 MHz, two
•
33MHz
127MHz and two 48MHz clocks. The SHUTDOWNB tri-
•
48MHz
states all the clocks when enabled. The device operates
•
127MHz
from a Supply
Voltage of 3.3V±5%V. The device is
• Zero ppm frequency synthesis error for all CLK outputs
available in a 16-pin TSSOP JEDEC package for
• 3.3V ± 5%V Supply Voltage
Industrial temperature range.
• Low jitter design
• Packaged in 16 pin TSSOP
Application
• Industrial Temperature range
PCS1P2859A is targeted for use in high-end multimedia,
• Compatible with CY22393XC-F12
communications
and
consumer
applications.
• Advanced low-power CMOS process
