Preliminary
NOTES:
1.
2.
For guaranteed specifications and test conditions, see the electrical characteristics. The guaranteed specifications apply
only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under
the listed test conditions.
3.
V
CC
supply pins 6, and 25 must be externally wired together to prevent internal damage during V
CC
power on/off
cycles.
4.
The supply current specified is the quiescent current for VCC
1
/VCC
2
and VCC3 with RL =
∞
, The supply current
for VCC2 (pin 25) also depends on the output load.
5.
Output voltage is dependent on load resistor. Test circuit uses RL = 390
6.
Measure gain difference between any two amplifiers Vin = 560mVpp.
7.
When measuring video amplifier bandwidth or pulse rise and fall times, a double sided full ground plane printed circuit
board without socket is recommended. Video amplifier 10MHz isolation test also requires this printed circuit board. The
reason for a double sided full ground plane PCB is that large measurement variations occur in single sided PCBs.
8.
Adjust input frequency from 10MHz (AV max reference level) to the-3dB frequency (f -3dB).
9.
Measure output levels of the other two undriven amplifiers relative to the driven amplifier to determine channel separation.
Terminate the undriven amplifier inputs to simulate generator loading. Repeat test at fin = 10MHz for Iso_10MHz.
10. A minimum pulse width of 200 ns is guaranteed for a horizontal line of 15kHz. This limit is guaranteed by design. if a lower
line rate is used a longer clamp pulse may be required.
11. During the AC test the 4V DC level is the center voltage of the AC output signal. For example. If the output is 4Vpp the
signal will swing between 2V DC and 6V DC.
12. These parameters are not tested on each product which is controlled by an internal qualification procedure.
Absolute maximum rating indicates the limit beyond which damage to the device may occur.
Operating ratings indicate conditions for which the device is functional but do not guarantee specific performance limits.
