Description
The Cypress series of network circuits are produced using
advanced 0.35 micron CMOS technology, achieving the indus-
tries fastest logic and buffers.
The Cypress CY2CC910 fanout buffer features one input and
ten outputs. Ideal for conversion from/to 3.3V/2.5V/1.8V
Designed for Data Communications clock management appli-
cations, the large fanout from a single input reduces loading
on the input clock.
Cypress employs unique AVCMOS type outputs VOI™
(Variable Output Impedance) that dynamically adjust for
variable impedance matching and eliminate the need for
series damping resistors and reduce noise overall.
