USING THE AD807
Ground Planes
Use of one ground plane for connections to both analog and
digital grounds is recommended.
Power Supply Connections
Use of a 10 F capacitor between V
mended. Care should be taken to isolate the 5 V power trace to
V
the CLKOUT and DATAOUT signals.
Use of 0.1 F capacitors between IC power supply and ground
is recommended. Power supply decoupling should take place as
close to the IC as possible. Refer to the schematic, Figure 12,
for recommended connections.
Transmission Lines
Use of 50
CLKOUT, and DATAOUT signals.
Terminations
Termination resistors should be used for PIN, NIN, CLKOUT,
and DATAOUT signals. Metal, thick film, 1% tolerance resistors
are recommended. Termination resistors for the PIN, NIN signals
should be placed as close as possible to the PIN, NIN pins.
Connections from 5 V to load resistors for PIN, NIN, CLKOUT,
and DATAOUT signals should be individual, not daisy chained.
This will avoid crosstalk on these signals.
Loop Damping Capacitor, C
A ceramic capacitor may be used for the loop damping capaci-
tor. Using a 0.15 F, +20% capacitor for a damping factor of
five provides < 0.1 dB jitter peaking.

AD807 Output Squelch Circuit
A simple P-channel FET circuit can be used in series with the
Output Signal ECL Supply (V
data outputs when SDOUT indicates a loss of signal (Figure 20).
The V
ECL loads, plus 5 mA for all 4 ECL output stages). This means
that selection of a FET with ON RESISTANCE of 0.5
affect the common mode of the ECL outputs by only 31 mV.
