Product specification
PAL/NTSC/SECAM synchronization
processor for video recorders
TDA3755
GENERAL DESCRIPTION
The TDA3755 is a monolithic integrated circuit for
PAL/NTSC SECAM synchronization processing in VHS
video recorders.
Features
• Adaptive sync separator
• Internal vertical sync pulse integrator
• Composite sync and vertical pulse output
• Current controlled oscillator (CCO) with 320/321 times
horizontal frequency
• Horizontal phase detector with current output
• Video identification and mute circuit
• Burst gating pulse output (externally adjustable phase
relationship)
• Test-picture output
• Subcarrier frequency output switched in phase in
accordance with VHS standard
• Fast phase correction of subcarrier frequency
• Selection input to force PAL or NTSC function
• Still picture input
