COMLINK™ SERIES
CY2CC1910
1:10 Clock Fanout Buffer with Output Enable
Features
Description
The Cypress series of network circuits are produced using
advanced 0.35-micron CMOS technology, achieving the
industries fastest logic and buffers.
The Cypress CY2CC1910 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 applications, 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; they also reduce noise overall.

Note:
1. Multiple Supplies: The Voltage on any input or I/O pin cannot exceed the power pin during power-up. Power supply sequencing is NOT required.
2. Stresses greater than those listed under absolute maximum ratings may cause permanent damage to the device. This is intended to be a stress rating only
and functional operation of the device at these or any other conditions above those indicated in the operation sections of this specification is not implied.
Exposure to absolute maximum rating conditions for extended periods may affect reliability.
