10 / 28 page 1997 Mar 04 10 Philips Semiconductors Product specification Video processor with automatic cut-off and white level control TDA4681 Table 2 Cut-off and white level measurement lines; notes 1 to 3 Notes 1. The line numbers given are those of the horizontal pulse counts after the start of the vertical component of the sandcastle pulse. 2. * line frequency of approximately 31 kHz. 3. (EB) is extended blanking. Table 3 Signal input selection by the fast source switches; notes 1 to 4 Notes 1. H: logic HIGH implies that the voltage >0.9 V. 2. L: logic LOW implies that the voltage <0.4 V. 3. X = don’t care. 4. ON indicates the selected input signal.
