ICS507-01/02
PECL Clock Synthesizer
Description
The ICS507-01 and ICS507-02 are inexpensive
ways to generate a low jitter 155.52 MHz (or other
high speed) differential PECL clock output from a
low frequency crystal input. Using Phase-Locked-
Loop (PLL) techniques, the devices use a standard
fundamental mode crystal to produce output
clocks up to 200 MHz.
Stored in each chip鈥檚 ROM is the ability to
generate a selection of different multiples of the
input reference frequency, including an exact
155.52 MHz clock from common crystals. For
lowest jitter and phase noise on a 155.52 MHz
clock, a 19.44 MHz crystal and the x8 selection
can be used.
