Philips Semiconductors Product specification Audio processor with head amplifier for VHS hi-fi TDA9605H Record-mute mode or head identification selection The state of the RM control signal on pin RMHID is don’t care in the playback mode. Pin RMHID allows input of two independent digital control signals for selecting the record-mute or head identification modes which are voltage coded. The RM control signal is selected via a 10 kΩ resistor and the HID control signal is selected via a 18 kΩ resistor.
Philips Semiconductors Product specification Audio processor with head amplifier for VHS hi-fi Table 2 LEVEL ON PIN RMHID RECORD MODE LOW lower than 2.35 V HIGH higher than 2.65 V record-mute mode 6.4.3 The DC bias current on pin RECOUT is changed proportional to the selected recording current for optimizing the performance and minimizing the power consumption for each recording current selected.
Philips Semiconductors Product specification Audio processor with head amplifier for VHS hi-fi 6.5 frequency difference between the left and right channel carrier near to 401.2 kHz. This value effectively reduces the crosstalk from hi-fi carriers to video colour signal as present during Extended Play (EP) tape speed. NTSC calibration uses a standard HID control signal of 29.97 Hz (pulse width =16.683 ms) where PAL calibration uses a standard HID control signal of 25 Hz (pulse width = 20 ms).
Philips Semiconductors Product specification Audio processor with head amplifier for VHS hi-fi Otherwise, the audio envelope output voltage may become >2.5 V which makes it impossible to detect the completion of the calibration on pin ENVOUT. 6.6 TDA9605H Power muting Switching off and on of the power supply voltage or using the built-in passive standby mode results in rising and dropping of the output DC voltages and causes strong disturbances on the output pins.
Philips Semiconductors Product specification Audio processor with head amplifier for VHS hi-fi During power muting the internal output signal is also muted. After the output DC voltage has been established power muting can be de-activated by setting bit MUTE = 0. Now the mute switches are opened resulting in a high-impedance path of 100 kΩ to ground. The output current limiting is not active. 6.

Philips Semiconductors Product specification Audio processor with head amplifier for VHS hi-fi 7.9.7 STANDBY SELECT 7.10.1 The TDA9605H is switched in the low-power active standby mode by setting bit STBA = 1. Most circuits are switched inactive for reducing power consumption. However, the RF converter, line and decoder outputs remain active in this mode and the direct audio selections offered via the line select function and the decoder select function remain available.
Philips Semiconductors Product specification Audio processor with head amplifier for VHS hi-fi 7.10.3 Detecting the occurrence of a Power-on reset by reading bit POR requires a setting of bit PORR = 1 after power-up. Bit POR is forced to logic 0 only by setting bit PORR = 1, so this setting is independent of other I2C-bus bit settings. CALIBRATION ERROR An unreliable calibration result is indicated when reading bit CALE = 1.
