Block Diagram
Description
Pericom Semiconductor's PI6C4512 is a precision general-
purpose clock synthesizer that reaches maximum 200MHz. This
device uses an external low-cost crystal to generate very accurate
rate and stable system clocks. This is the most cost effective way to
reduce high-price, high frequency crystals. Using PLL techniques,
the device uses a standard fundamental mode, inexpensive crystal
to produce output clocks up to 200 MHz.
The internal Logic divider is to generate nine different popular
multiplication factors, allowing one chip to output many common
frequencies.
