FEATURES:
DESCRIPTION:
Advanced CMOS Technology Guaranteed low skew < 100ps (max.) Very low duty cycle distortion< 250ps (max.) High speed propagation delay< 2ns (max.) Very low CMOS power levels TTL compatible inputs and outputs 1:10 fanout Maximum output rise and fall time < 1ns (max.) Low input capacitance: 3pF typical VCC = 3.3V 0.3V Inputs can be driven from 3.3V or 5V components Operating frequency up to 166MHz Available in SSOP and QSOP packages
The FCT3807 is a 3.3V clock driver built using advanced CMOS technology. This low skew clock driver offers 1:10 fanout. The large fanout from a single input reduces loading on the preceding driver and provides an efficient clock distribution network. Multiple power and grounds reduce noise. Typical applications are clock and signal distribution.

NOTES: 1. See test circuits and waveforms. 2. Minimum limits are guaranteed but not tested on Propagation Delays. 3. tPLH, tPHL, tSK(P), and tSK(O) are production tested. All other parameters guaranteed but not production tested. 4. 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. 5. Skew measured between all outputs under identical transitions and load conditions. 6. Skew measured is difference between propagation delay times tPHL and tPLH of same output under identical load conditions. 7. Part to part skew for all outputs given identical transitions and load conditions at identical VCC levels and temperature. 8. Airflow of 1m/s is recommended for frequencies above 133MHz.
