COMLINK™ SERIES CY2CC910 1:10 Clock Fanout Buffer Features • Low-voltage operation • Full-range support: — 3.3V — 2.5V • • • • • • • • — 1.8V Over voltage tolerant input hot swappable 1:10 fanout Drives either a 50-Ohm or 75-Ohm load Low-input capacitance Low-output skew Low-propagation delay Typical (tpd < 4 ns) High-speed operation: — -200 MHz@1.8V — 650 MHz@2.5V/3.3V • 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 CY2CC910 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 and reduce noise overall.
