DESCRIPTION
AA8600AP is a Y/C mix with 6db gain, 75Ω output buffer and SAG correction.
The 75Ω buffer is capable of driving two circuits. The SAG could reduce the
capacitance of output coupling capacitor. The Y signal is clamped input, while the
C signal is biased input. The power saving circuit provides the output and
chrominance muting function. The IC is available in 8-pin TSSOP.

NOTE : Stress above those listed under “Absolute Maximum Rating” may cause
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated
in the operational section of this specification is not implied. Exposure to
absolute maximum rating conditions for the extended periods of time may
affect device reliability.

Input a 4.43MHz, 1Vp-p
sine wave from CIN and
then measure the output
level from VO1
GV1M : voltage gain at
input frequency=1MHz
GV7M : voltage gain at
input frequency=7MHz
GF=GV7M-GV1M
Input a 4.43MHz, 1Vp-p
sine wave and then
measure the output level
from VO1
Same as output muting
Measure the input voltage
VIS & the open voltage
VIO when a 50uA is
introduced. The ZIN =
|VIS-VIO| / 50uA
Measure the current of
power supply when mute
is set at high
Measure the value of TS
and To at the first as VS1
& VO1 and the value at
second condition as VS2
& VO2, respectively.
GSAG= 20log{(VS2 - VS1)
/ (VO2 - VO1) }
