SONY CXA1814

CXA1814N
8 mm VCR ATF
Description
The CXA1814N is an IC developed for ATF
(Automatic Track Finding) in 8 mm VCRs, and
integrates the major functions necessary for ATF
onto a single chip.
30 pin SSOP (Plastic)
Features
• Built-in pilot signal detector and BPF
• Adopts a high-precision analog filter with no
switching noise
• Built-in SP/LP identification circuit and clog
detection circuit
• Low noise, high-precision bipolar process
Applications
