Product Description

The PCS1P2858A is a versatile multi output clock

generator. The PCS1P2858A uses the latest PLL

technology. The six Clock outputs are generated using

an inexpensive 27MHz Crystal. The accuracy of the

27MHz Input Clock should be within ±50ppm. The

outputs consist of 24.576MHz, 24 MHz, 10MHz, and

28.322 MHz clocks together with two 27 MHz reference

clock. The OE tri-states all the clocks when disabled.

The device operates from a Supply

Voltage of

3.3V±5%V. The device is available in a 16-pin TSSOP

JEDEC package.

Application

PCS1P2858A is targeted for use in HDTV digital video
