VCO0Dh VCO-M (0) [ Sub; 0Dh D1 1 bit ] Data Descriptions 0 Absolute (duration of searching) 1 Relative (normal) VCO tuning mode TB1261 has two VCO tuning mode, which are 'Absolute' and 'relative'. The 'Absolute' mode refers the crystal oscillation frequency 4.43MHz, the 'Relative' mode refers the IF input frequency, which is tuned by AFT loop. Set 'Relative' mode in normal receiving, and 'Absolute' in channel searching. Even setting the 'Relative' mode, the VCO mode works as 'Absolute' in status of 'PIF Unlock' automatically.

This mode is available only for the TB1262. This bit set to L-system as to; - Turn the modulation polarity to positive - Delay the AGC time constant (Peek AGC), with switching the IF AGC filter to the capacitor of DCNF pin (10uF) instead of IFAGC pin (0.47uF) . - SIF AM demodulation (Split carrier only) with switching the SIF AGC filter to the capacitor of IFAGC pin (0.47uF) . {L-SECAM AGC speed up} Speed up the AGC response for channel search {FM Stop} Stopping the FM demodulator to use in NICAM demodulation.
