PCS1P2858A

Multi-Output Clock Generator

Product Description

Features

• Generates multiple clock outputs from an inexpensive

27MHz crystal .

• Frequency outputs:

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.
