| COMLINKTM SERIES CY2CC810 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 < 4 ns) High-speed operation > 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.
