INTEGRATED CIRCUITS DATA SHEET TDA4691 Sync Processor with Clock (SPC) Preliminary specification File under Integrated Circuits, IC02 September 1993 Philips Semiconductors Preliminary specification Sync Processor with Clock (SPC) FEATURES · Sync processor for horizontal (H) and vertical (V) sync pulses generated by internal 13.5 MHz oscillator · Stable `On Screen Display (OSD)', if no input signal is present with free running internal oscillator; automatic turn over to locked oscillator, if input signal is available · External clock oscillator can be used · Standard 50/60 Hz signals are identified automatically · Additional outputs for 13.5 MHz, composite sync, 50//60 Hz identification, signal identification (mute), super-sandcastle 12 V · TTL compatible outputs (H, V, composite sync and 13.5 MHz) · 3 different time constants for the PHI1 PLL: fast, normal and slow (T1, T2 and T3). Fast and normal time constant are set independent from each other · Start of H-pulse definable by application · Digital interference reduction for H and V signals · Digital noise detector · Time correction of non-standard H-pulses and equalizing pulses for optimum PLL control. GENERAL DESCRIPTION The TDA4691 is a bipolar integrated circuit for sync processing in 50/100 and 60/120 Hz TV sets, preferably in conjunction with the programmable deflection controller TDA9150. A line locked 13.5 MHz clock with several dividers and logic circuitry is available generating the horizontal and vertical sync outputs. The device can be assembled in a DIL20 or SO20 package.
