U4930B

The U4930B has the following features including Multiple video switch with two CVBS inputs and a SVHS (or third CVBS) input;CVBS output signals for the teletext decoder and a SCART interface;Y delay, sharpness control and black level stretcher function in the luminance channel;Integrated and auto-tuned chroma traps, band pass filters;PAL/NTSC  color  decoder  with  automatic  color standard decoder;Easy interfacing with an add-on SECAM decoder for multistandard applications;RGB control with cut-off and white point adjustment,linear RGB input and fast blanking;Synchronization  with  drive  circuits  for  H/V deflection;Vertical compression of the picture for 16:9 on 4:3 TV sets.

The U4930B is an alignment-free, IZC-bus controlled TV baseband processor that has been designed for use with the baseband delay line U3665M and the SECAM decoder U4935B.The IC includes a multiple video-input selector switch,chroma filters,sharpness control and black level stretcher function,   PAL/NTSC   color   decoder,   luminance processor,  RGB  control,  the  sync  and  deflection processor.The IC is realized in a bipolar VLSI technology and operates with +5/+8 V supply voltage. Easy interfacing and the optional add-on  SECAM decoder U4935B provides flexibility to design a multistandard TV.Each transmission must begin with a start condition and end with a stop condition. Between a start and a stop condition, when SCL is HIGH, the data fine SDA must be stable. Only while SCL is LOW is the data fine allowed to change. Each transmission consists of at least three bytes. Each byte has to be followed immediately by an acknowledge bit "A".

In the  autoincrement  mode, the subaddress U4930B can  be followed by more than one byte. The bytes from the third byte on will all be interpreted as data. The subaddress will be internally automatically incremented and the IC stores the data successively in the correct registers.Parameters can vary in different applications. All operating parameters must be validated for each customer application by the customer. Should the buyer use TEMIC U4930B products for any unintended or unauthorized application, the buyer shall indemnify TEMIC U4930B against all claims, costs, damages, and expenses, arising out of,directly or indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
