Product Description
The PCS1P2857A/B is a versatile multi output clock
generator. The PCS1P2857A/B uses the latest PLL
technology. The four Clock outputs are generated using
an inexpensive 27MHz Crystal. The accuracy of the
27MHz Input Clock should be within ±50ppm. The
outputs consist of 24 MHz, 14.31818 MHz, and 28.322
MHz clocks together with a 27 MHz reference clock. The
device operates from a Supply Voltage of 3.3V±5%V.
The device is available in a 8 pin SOIC and 8 pin TSSOP
JEDEC package.
Application
PCS1P2854A/B is targeted for use in HDTV digital video.
