9 / 14 page 522 - 06 - 02 9 The diagram below depicts the active portions of the chip when operating in Receiver mode (Rx/Tx set to logic high level) with the equalizer, descrambling and NRZI functions all active. In this mode of operation the output of the LOCK pin is logic high whenever the receiver has successfully locked to the input serial bit stream. The output H is set low after the SAV ID and is set high after the EAV ID when these sequences are identified in the incoming bit stream. Note the function available called "Equalizer Control" (EQ). Setting EQ to a logic HIGH level shuts off the equalization function of the device for implementations where the length of cable to be equalized is very short (less than 10 m). It is possible to turn off the NRZI and SMPTE Descrambler function by setting SMPTE HIGH. When operating in this mode, the output of H, will be either "1" or "0" (indeterminate). Fig. 18 Functional Block Diagram (Receiver Mode) The diagram below depicts the active portions of the chip when operating in Transmitter mode (Rx/Tx set to logic low level), with the NRZI and scrambling functions active. Note that similar to receive mode above, it is possible to turn off the NRZI and SMPTE Scrambler by setting SMPTE high.
