Description
The PI6C49X0210-Ais a high performance multi-voltage 10-outputs
CMOS Fanout Buffer with internal Crystal Oscillator. The XTAL
range is from 10MHz to 50MHz. The device has a wide range of
operating voltages of 2.5V and 3.3V. The device also provides user
selectable outputVDD option, which provides excellent flexibilities
to users. This device is ideal for systems that need to distribute low
jitter clock signals to multiple destinations.

Notes:
1. Unless noted otherwise, all parameters are tested with xtal @ f <= Fxtal_max,; outputs are terminated @ 50Ω to VDDO/2, see waveforms.
2. Diff external clock source is driving IN0/IN0# and IN1/IN1# input. IN0/IN1 can be single end ref clock when IN0# /IN1# set as VDD/2
3. Identical conditions: loading, transitions, supply voltage, temperature, package type and speed grade.
4. These parameters are guaranteed, but not tested. Max delay is 4 cycles. Min. setup time = 3ns.
