1-TO-10 CLOCK DRIVER

DESCRIPTION:

The FCT3807 is a 3.3V clock driver built using advanced CMOS technol-

ogy. 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.

3.3V CMOS 1-TO-10 CLOCK DRIVER

NOTES:

1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.

2. Typical values are at VCC = 3.3V, +25°C ambient.

3. This parameter is not directly testable, but is derived for use in Total Power Supply calculations.

4. IC = IQUIESCENT + IINPUTS + IDYNAMIC

IC = ICC + ∆ICC DHNT + ICCD (fi)

ICC = Quiescent Current

∆ICC = Power Supply Current for a TTL High Input (VIN = VCC -0.6V)

DH = Duty Cycle for TTL Inputs High

NT = Number of TTL Inputs at DH

ICCD = Dynamic Current Caused by an Input Transition Pair (HLH or LHL)

fi = Input Frequency

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.
