SERIAL PROGRAMMABLE PCI SS VERSACLOCK SYNTHESIZER
Description
The MK1716-01 is a versatile serial programmable clock
source which takes up very little board space.
The device can simultaneously generate two groups of 4
output clocks and a reference clock output. Both clock
groups (CLKA and CLKB) are derived from a single PLL,
and have the ability to incorporate Spread Spectrum
frequency modulation for reduced system EMI. Each group
has control of independent PLL output divide values.
Outputs may be programmed on the fly, and will lock to a
new frequency in 10 ms or less.
Each of the two groups are powered by a separate VDDIO
voltage. The reference clock uses the fixed VDD voltage.
VDDIO may vary from 2.5 V to VDD.
The devices includes a OE pin which tri-states the output
clocks and when tied low.
IDT’s VersaClock
