Download Datasheet for Philips Semiconductors TDA8373 I2C-bus controlled NTSC TV-processor [72 pages SCA54 1997 pdf/zip]
Available in all ICs:
– Vision IF amplifier with high sensitivity and good figures for differential phase and gain
– PLL demodulator for the IF signal
– Alignment-free sound demodulator
– Flexible source selection with a CVBS input for the internal signal and Y/C or CVBS input for the external signal
– Audio switch
– The output signal of the CVBS (Y/C) switch is externally available
– Integrated chrominance trap and band-pass filters (auto-calibrated)
– Luminance delay line integrated
– A symmetrical peaking circuit in the luminance channel
– Black stretching of non-standard CVBS or luminance signals
– RGB control circuit with black current stabilization and white point adjustment
– Linear RGB inputs and fast blanking
– Horizontal synchronization with two control loops and alignment-free horizontal oscillator
– Slow start and slow stop of the horizontal drive pulses
– Vertical count-down circuit
– Vertical driver optimized for DC-coupled vertical output stages
– I2C-bus control of various functions
– Low dissipation
– Small amount of peripheral components compared with competition ICs.
The various versions of the TDA837x series are I2C-bus controlled single-chip TV processors which are intended to be applied in PAL/NTSC (TDA8374 and TDA8375) and NTSC (TDA8373 and TDA8377) television receivers.
All ICs are available in an SDIP56 package and some versions are also available in a QFP64 package. The ICs are pin compatible so that with one application board NTSC and PAL/NTSC (or multistandard together with the SECAM decoder TDA8395) receivers can be built.
Functionally this IC series is split in to 2 categories:
– Versions intended to be used in economy TV receivers with all basic functions
– Versions with additional functions such as E-W geometry control, horizontal and vertical zoom function and YUV interface which are intended for TV receivers with 110 deg. picture tubes.
Helped you out?
Glad to hear that. It would be awesome if you could . . .
