CXA1704R
2-channel REC/PB Amplifier for 8mm VCR
Description
The CXA1704R is a bipolar IC designed as a
recording/playback amplifier for Hi8-compatible
VCRs.
48 pin LQFP (Plastic)
Features
O Recording system
• Feedback damping provided in the recording
amplifier and its EVR control function facilitate
circuit board design.
• Y, chroma, and low-band level adjustment
functions
• Ramp circuit
O Playback system
• Feedback damping provided in the playback
amplifier facilitates circuit board design.
• Middle-frequency tuner on chip; EVR permits
independent adjustment of f0, Q and boost
• RF AGC and dropout detection circuit
Absolute Maximum Ratings (Ta=25°C)
• Supply voltage
VCC 7 V
• Operating temperature Topr –10 to +75 °C
• Storage temperature Tstg –65 to +150 °C
• Allowable power dissipation
PD 1100 mW
(when board is mounted)
Operating Conditions
Supply voltage
+0.5 V
VCC 4.75

RF AGC input of playback Y level.
The playback video signal output
from Pin 14 (MTOUT) passes
through an external ATF TRAP,
AFM TRAP, and C TRAP, and is
then input to Pin 10 (RFAGCIN)
again.
DC is cut off by internal capacitor.
When not used, connect this pin to
Vcc.
Determines the dropout detection
level.
