HA11566NT
TV-VTR PLL Detector and SAW Split PIF Plus SIF
The HA11566NT adopts both the SAW split
system and a PLL video detection system, and has
superior audio and video S/N ratio, and video
output linearity characteristics.
Features
• Excellent video frequency 11.5MHz (3dB down)
and video output linearity
• Excellent video S/N and 920-kHz beat
characteristics
• Audio noise and audio buzz have been reduced
• Small packaging (DP-22NS)
