PRELIMINARY
Y/C MIX
FEATURE
1. Y/C mix circuit
2. Output and Chrominance muting function
3. Output protection function
4. SAG correction function
5. A load sufficient for driving two circuits
APPLICATION
VCR
Video Camera
TV
Video Player
6. Low power consumption, 60mw typical
7. Internal voltage clamp circuit
DESCRIPTION
AA8600 is a Y/C mix with 6db gain, 75Ωoutput buffer and SAG correction. The
75Ωbuffer 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.

Measurement Method

C No signal input
Input a 4.43MHz, 1Vp-p
C
sine wave from CIN and
then measure the output
level from VO1
GV1M : voltage gain at
input frequency=1MHz
C GV7M : voltage gain at
input frequency=7MHz
GF=GV7M-GV1M
Input a 4.43MHz, 1Vp-p
sine wave and then
C measure the output level
from VO1
C Same as output muting
Measure the input voltage
VIS & the open voltage
C VIO when a 50uA is
introduced. The ZIN =
|VIS-VIO| / 50uA
Measure the current of
C power supply when mute
is set at high
C Measure the value of TS
O
and To at the first as VS1
& VO1 and the value at
second condition as VS2
& VO2, respectively.
GSAG= 20log{(VS2 - VS1)
/ (VO2 - VO1) }
