TEST PROCEDURE
1.




Board Setup:
0.1 uF input coupling capacitors
220uF output coupling capacitors
75 ohms input matching impdance
75 output resistors
2.


Power Supply:
Plug the GND first.
Limit the current to 100mA.
Then, plug Vcc at 5V
Turn on the supply.
3. Standard definition channel:
 Apply 1Vpp with 0V offset, 1MHz sinewave on all the input HD INx (pin 1, 2, 3)
 Measure a sine wave of 1MHz on the output (pin 12, 13, 14) centered around 0V
with an amplitude an amplitude of 2.6Vpp at the output of the device.
 Icc should be around 23mA.
