SERIAL PROGRAMMABLE CLOCK WITH SPREAD SPECTRUM
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.
ICS’ VersaClockTM software allows the user to
generate MK1716-01 device optimizing configuration
code for target output frequencies and spread
spectrum amounts.
