Clock Distribution ICs Offer Low Skew

Channel-to-channel clock skew of less than 10 ps, speeds of up to 2.6 GHz, and jitter of less than 1 ps are all features of the SK15xx (1:5 output) and SK19xx (1:9 output) clock distribution IC families. The chips integrate data synchronization logic and termination components with the clock distribution capability in a 5 mm x 5 mm TQFP package.A host of options are available, including open emitter or 50 ohm terminated output versions, providing engineers with design flexibility. The 50 ohm output option with pull-down current source eliminates as many as 18 external resistors. The ICs operate from either a 3.3V or 5.2V supply.
