General Description
The 874208I is a high-performance differential LVDS clock divider
and fanout buffer. The device is designed for the frequency division
and signal fanout of high-frequency, low phase-noise clocks. The
874208I is characterized to operate from a 2.5V power supply.
Guaranteed output-to-output and part-to-part skew characteristics
make the 874208I ideal for those clock distribution applications
demanding well-defined performance and repeatability. The
integrated input termination resistors make interfacing to the
reference source easy and reduce passive component count. Each
output can be individually enabled or disabled in the high-impedance
state controlled by a I2C register. On power-up, all outputs are
enabled.
