Description
The Cypress series of network circuits are produced using
advanced 0.35 micron CMOS technology, achieving the
industry’s fastest logic and buffers.
The Cypress CY2CC910 fanout buffer features one input and 10
outputs. It is ideal for conversion from and to 3.3V, 2.5V, and 1.8V
Designed for Data Communications clock management applica-
tions, the large fanout from a single input reduces loading on the
input clock.
Cypress employs the unique AVCMOS type outputs VOI
(Variable Output Impedance) that dynamically adjust for variable
impedance matching, eliminate the need for series damping
resistors, and reduce overall noise.
