16 Output Low Skew Clock Generator
Description
The MK74CG117A is a monolithic CMOS high-speed,
low-skew clock driver that includes an on-chip PLL.
Ideal for communications and other systems that
require a large number of high-speed clocks, the
unique combination of PLL and 16 low-skew outputs
can eliminate oscillators and low-skew buffers from
systems.
The device has a number of built-in multipliers, making
it possible to run from one inexpensive, low-frequency
crystal, and produce high-frequency clock outputs.
Another selection allows the chip to run as a divider,
dividing the input clock by two (or 4 using the mode
select).
The device also has a buffered reference output,
allowing multiple devices to be easily driven from one
clock source.
Features
48-pin SSOP (300 mil) package
On-chip PLL generates output clocks up to 90 MHz
from a simple crystal or clock input
16 low-skew outputs

Ability to configure as
– 16 clocks at full-frequency
– 12 at full and 4 at half-frequency
– 8 at full and 8 at half-frequency
Tri-state mode for Output Enable function
3.3 V ±5% supply voltage
