CXA1737R
AFM Stereo Signal Processor for 8 mm VCR
Description
The CXA1737R is a bipolar IC designed as an
AFM stereo signal processor for 8mm VCR.
All functions necessary for AFM stereo are
concentrated onto a single 64-pin LQFP.
64 pin LQFP (Plastic)
Features
• Low supply voltage (3.15V) design
• Low power consumption (Vcc = 3.15V)
Recording: 150mW
Playback: 240mW
• Built-in BPF (1.5MHz, 1.7MHz)
Supports NTSC and PAL
Enables both parallel and 3-line serial mode control
Supports electronic volume (EVR) control
Structure
Bipolar silicon monolithic IC
