1:10 Clock Fanout Buffer
Features
· · · · · · · · · · · · 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 Low-output skew Low-propagation delay Typical (tpd 500 MHz Industrial versions available Available packages include: SOIC, SSOP
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 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 eliminate the need for series damping resistors; they also reduce noise overall.

Notes: 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.
