Multi-Output Clock Generator
Features
Product Description
• Generates multiple clock outputs from an inexpensive
The PCS1P2858A is a versatile multi output clock
generator. The PCS1P2858A uses the latest PLL
27MHz crystal .
• Multiple Clock outputs:
technology. The six Clock outputs are generated using
•
27MHz Reference clock
an inexpensive 27MHz Crystal. The accuracy of the
•
27MHz Reference clock
27MHz Input Clock should be within ±50ppm. The
•
10MHz
outputs consist of 24.576MHz, 24 MHz, 10MHz, and
•
24MHz
28.322 MHz clocks together with two 27 MHz reference
•
28.322MHz
clock. The OE tri-states all the clocks when disabled.
•
24.576MHz
The device operates from a Supply
Voltage of
• Supply Voltage:3.3V ± 5%V
3.3V±5%V. The device is available in a 16-pin TSSOP
• 16 pin TSSOP Package
JEDEC package.
• Commercial Temperature range
• Low-power CMOS process.
Application
PCS1P2858A is targeted for use in HDTV digital video
