... TDA7511 1 FUNCTIONAL DESCRIPTION 1.1 FM Section 1.2 Mixer1, AGC and 1.IF Mixer1 is a wide dynamic range stage with low noise and large input signal performance. The mixer1 tank can be adjusted by software (IF1T). The AGC operates on different sensitivities and bandwidths (FMAGC) in order to improve the input sensitivity and dynamic range (keying AGC). The output signals of AGC are controlled volt- age and current for preamplifier and prestage pin diode attenuator ...

... I C-Bus interface.The reference frequency is generated by an adjustable internal (XTAL) oscillator followed by the reference divider. The reference and step-frequencies are free selectable (RC, PC). Output signals of the phase detector are switching the programmable current sources. The loop filter integrates TDA7511 15/41 ...

... TDA7511 their currents voltage. The values of the current sources are programmable by 6 bits also received via the I To minimize the noise induced by the digital part of the system, a special guard area is implemented. The loop gain can be set for different conditions by setting the current values of the chargepump generator. ...

... The precision of the measurements is adjustable by controlling the discrimination window. This is adjustable by programming the control registers EW0 to EW2. The measurement time per cycle is adjustable by setting the Register IFS0 - IFS2. Adjust of the Frequency Value The center frequency of the discrimination window is adjustable by the control register CF0 to CF4. FM mode AM up conversion mode IF TDA7511 17/41 ...

... TDA7511 2 1.8 I C-Bus Interface 2 The TDA 7511 supports the I C-Bus protocol. This protocol defines any device that sends data onto the bus as a transmitter, and the receiving device as the receiver. The device that controls the transfer is a master and device being controlled is the slave. The master will always initiate data transfer and provide the clock to trans- mit or receive operations ...
