TDA9884
I2C-bus controlled multistandard alignment-free IF-PLL
Switching to the mute state is controlled automatically, dependent on the digital
acquisition help in case the VCO of the FM-PLL is not in the required frequency window.
This is done by a time constant: fast for switching to the mute state and slow (typically
40 ms) for switching to the no-mute state.
All switching functions are controlled via the I2C-bus:
AM sound, FM sound and forced mute
Auto mute enable or disable
De-emphasis off or on with 50
s or 75 s
Audio gain normal or reduced
7.15 Internal voltage stabilizer
The band gap circuit internally generates a voltage of approximately 2.4 V, independent of
supply voltage and temperature. A voltage regulator circuit, connected to this voltage,
produces a constant voltage of 3.55 V which is used as an internal reference voltage.
7.16 I2C-bus transceiver and module address
The device can be controlled via the 2-wire I2C-bus by a microcontroller. Two wires carry
serial data (SDA) and serial clock (SCL) information between the devices connected to
the I2C-bus.
The device has an I2C-bus slave transceiver with auto-increment. The circuit operates up
to clock frequencies of 400 kHz.
A slave address is sent from the master to the slave receiver. To avoid conicts in a real
application with other devices providing similar or complementing functions, there are four
possible slave addresses available. These Module Addresses (MADs) can be selected by
connecting resistors on pin SIOMAD and/or pins SIF1 and SIF2 (see Figure 23).
Pin SIOMAD relates to bit A0 and pins SIF1 and SIF2 relate to bit A3. The slave
addresses of this device are given in Table 4.
The power-on preset value is dependent on the use of pin SIOMAD and can be chosen for
45.75 MHz NTSC as default (pin SIOMAD left open-circuit) or 58.75 MHz NTSC (resistor
on pin SIOMAD). In this way the device can be used without the I2C-bus as an NTSC only
device.
Remark: In case of using the device without the I2C-bus, then the rise time of the supply
voltage after switching on power must be longer than 1.2
s.
