PI6C49X0208
High Performance 1:8 Multi-Voltage CMOS Buffer
Description
Features
e DIODES PI6C49X0208 is a high performance multi-voltage
8-outputs CMOS Fanout Buffer with internal Crystal Oscillator.
e XTAL range is from 10MHz to 50MHz. e device has a
wide range of operating voltages of 2.5V and 3.3V. e device
also provides user selectable output VDD option, which provides
excellent flexibility to users. is device is ideal for systems that
need to distribute low jitter clock signals to multiple destinations.
yꢀ8 single-ended outputs fanout buffer
yꢀUp to 200MHz output frequency
yꢀUltra low output additive jitter = 0.01ps (typical)
yꢀSelectable reference inputs support Xtal (10~50MHz), single-
ended and differential
yꢀLow output skew ~ 50ps (typical)
yꢀ2.5V/3.3V operation
yꢀUser configurable output VDDO in different banks:
