2.5V CMOS 1-TO-10 CLOCK DRIVER
Features
Product Description
•
High frequency > 150MHz
•
Guaranteed low skew < 150pS (max.) between
any two outputs
•
Very low duty cycle distortion < 300pS
•
High speed: propagation delay < 3nS
•
Very low CMOS power levels
PCS20807A is an ideal clock distribution device for
•
TTL compatible inputs and outputs
synchronous systems. Multiple power and grounds reduce
•
1:10 fanout
noise. Typical applications are clock and signal distribution.
•
Maximum output rise and fall time < 1.25nS
(max.)
•
Low input capacitance: 3pF (typ)
•
2.5V Supply Voltage
•
Available in SSOP and QSOP Packages
The PCS2P20807A is a 2.5V compatible, high speed, low
noise, 1:10 fanout, non-inverting clock buffer. The large
fanout from a single input reduces loading on the preceding
driver and provides an efficient clock distribution network.
Providing output to output skew as low as 150pS, the

NOTES:
1. tPLH and tPHL are production tested. All other parameters guaranteed but not production tested.
2. Propagation delay range indicated by Min. and Max. limit is due to VCC, operating temperature and process parameters. These propagation delay limits do
not imply skew.
3. See test circuits and waveforms.
4. Skew measured between all outputs under identical transitions and load conditions.
5. Skew measured is difference between propagation delay times tPHL and tPLH of same output under identical load conditions.
6. Part to part skew for all outputs given identical transitions and load conditions at identical VCC levels and temperature.
7. Airflow of 1m/s is recommended for frequencies above 133MHz.
