Description
Low-voltage operation
VDD range from 2.5V to 3.3V
1:10 fanout
Over voltage tolerant input hot swappable
Drives either a 50-Ohm or 75-Ohm transmission line
Low-input capacitance
250 ps typical output-to-output skew
19 ps typical DJ jitter
Typical propagation delay < 3.5 ns
High-speed operation > 500 MHz
Industrial versions available
Available packages include: SOIC, SSOP
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 CY2CC810 fanout buffer features one input and
ten outputs. Designed for data communications clock
management applications, the large fanout from a single input
reduces loading on the input clock.
AVCMOS-type outputs dynamically adjust for variable
impedance matching and reduce noise overall.

Note
1. 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.
2. 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.
