The SDA5648 is intended for use in video cassette recorders to retrieve control data of the PDC system from the data lines broadcast during the vertical blanking interval of a standard video signal. The features of SDA5648 are: (1)reception of unified date a...
The function of SDA5642X is to regenerate the biphase coded VPS data from the CVBS signal. These data are transferred during line 16, which is part of the vertical blanking time. After decoding and a check for transmission errors, these data can be acquired ...
