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 voltage and current for preamplifier and prestage pin diode attenuator. (look at Figure 4) Two 10.7MHz programmable amplifiers (IFG1, IFG2) correct the IF ceramic insertion loss and the costumer level plan application. 1.3 Mixer2, Limiter and Demodulator In this 2. mixer stage the first 10.7MHz IF is converted into the second 450kHz IF. A multi-stage limiter generates signals for the complete integrated demodulator without external tank. MPX output DC offset compensation is possible by software (DEM). 1.4 Quality Detection and ISS (look at Figure 2) Fieldstrength Parallel to mixer2 input a 10.7MHz limiter generates a signal for digital IF counter and a fieldstrength output signal. This internal unweighted fieldstrength is used for keying AGC, adjacent channel and multipath detection and is available at PIN14 (FSU) after +6dB buffer stage. The behaviour of this output signal can be corrected for DC offset (SL) and slope (SMSL). The internal generated unweighted fieldstrength is filtered at PIN35 and used for softmute function and generation of ISS filter switching signal for weak input level (sm). Adjacent Channel Detector The input of the adjacent channel detector is AC coupled from internal unweighted fieldstrength. A programmable highpass or bandpass (ACF) and amplifier (ACG) as well as rectifier determines the influences. This voltage is compared with adjustable comparator1 thresholds (ACWTH, ACNTH). The output signal of this comparator generates a DC level at PIN15 by programmable time constant. Time control (TISS) for a present adjacent channel is made by charge and discharge current after comparator1 in an external capacitance. The charge current is fixed and the discharge current is controlled by I2C Bus. This level produces digital signals (ac, ac+) in an additional comparator4. The adjacent channel information is available as analog output signal after rectifier and +8dB output buffer. Multipath Detector The input of the multipath detector is AC coupled from internal unweighted fieldstrength. A programmable bandpass (MPF) and amplifier (MPG) as well as rectifier determines the influences. This voltage is compared with an adjustable comparator2 thresholds (MPTH). The output signal of this comparator2 is used for the "Milano" effect. In this case the adjacent channel detection is switched off. The "Milano" effect is selectable by I2C Bus (MPOFF). The multipath information is available as analog output signal after rectifier and +8dB output buffer. 450kHz IF Narrow Bandpass Filter (ISS filter) The device gets an additional second IF narrow bandpass filter for suppression noise and adjacent channel signal influences. This narrow filter has three switchable bandwidthes, narrow range of 80kHz, mid range of 120kHz and 30KHz for weather band information. Without ISS filter the IF bandwidth (wide range) is defined only by ceramic filter chain. The filter is switched in after mixer2 before 450kHz limiter stage. The centre frequency and matching to the demodulator center frequency can be fine adjusted (AISS) by software.. Deviation Detector In order to avoid distortion in audio output signal the narrow ISS filter is switched OFF for present overdeviation. 14/41 TDA7511 Hence the demodulator output signal is detected. A lowpass filtering and peak rectifier generates a signal that is defined by software controlled current (TDEV) in an external capacitance. This value is compared with a programmable comparator3 thresholds (DWTH, DTH) and generates two digital signals (dev, dev+). ISS Switch Logic All digital signals coming from adjacent channel detector, deviation detector and softmute are acting via switching matrix on ISS filter switch. The IF bandpass switch mode is controlled by software (ISSON, ISS30, ISS80, ISSCTL). The switch ON of the IF bandpass is also available by manipulation of the voltage at PIN15. Two application modes are available (APPM). The conditions are described in table 37. 1.5 Soft Mute Control The external fieldstrength signal at PIN 35 is the reference for mute control. The startpoint, mute depth and slope are programmable (SMTH, SMD, SLOPE) in a wide range. The time constant is defined by external capacitance. Additional adjacent channel mute function is supported. A highpass filter with -3dB threshold frequency of 100kHz, amplifier and peak rectifier generates an adjacent noise signal from MPX output with the same time constant for softmute. This value is compared with comparator5 thresholds (ACM). For present strong adjacent channel the MPX signal is attenuated typical 6dB. 1.6 AM Section The upconversion mixer1 is combined with a gain control circuit 1 sensing three input signals, narrow band information at PIN 39, upconversion signal at PIN 58 and wide band information at PIN 3.This gain control circuit gives two output signals. The first one is a current for pin diode attenuator and the second one is a voltage for preamplifier. It is possible to put in a separate narrow bandpass filter before mixer2 at PIN 58. The intervention point for first AGC (AMAGC) is programmable by software. The oscillator frequency for mixer1 is generated by dividing the FM VCO frequency (AMD). In mixer2 the IF1 is downconverted into the IF2 450kHz. Before the output signal reaches the 450kHz tank an attenuator for IF gain control 2 is passed. Mixer1 and mixer2 tanks are software controlled adjustable (IF1T, IF2T). After filtering by ceramic filter a 450kHz amplifier with a gain control 3 is included. The gain control 2 and 3 are the second AGC and programmable too by software (DAGC). In order to avoid an oscillation in intervention point it is important to know that the DAGC threshold has to be smaller than AMAGC! . The demodulator is a peak detector. A further time constant with capacitor at pin40 produces a DC AGC reference voltage dependent on input signal. The time constant is switchable by ratio of 30. This is necessary for the station search function. The switching is software controlled (AMSEEK). An internal comparator compares the AGC voltage with a programmable reference (AMSS). Consequently it is possible to generate a seekstop impulse over a defined range. A separate output is available for AMIF stereo or a permanent seek stop signal(SSTSEL). 1.7 PLL and IF Counter Section PLL Frequency Synthesizer Block This part contains a frequency synthesizer and a loop filter for the radio tuning system. Only one VCO is required to build a complete PLL system for FM and AM upconversion. For auto search stop operation an IF counter system is available. The counter works in a two stages configuration. The first stage is a swallow counter with a two modulus (32/33) precounter. The second stage is an 11-bit programmable counter. The circuit receives the scaling factors for the programmable counters and the values of the reference frequencies via an I2C-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 15/41 TDA7511 their currents to a DC voltage. The values of the current sources are programmable by 6 bits also received via the I2C Bus (A, B, CURRH, LPF). 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. Frequency Generation for Phase Comparison The RF signals applies a two modulus counter (32/33) pre-scaler, which is controlled by a 5-bit divider(A). The 5-bit register (PC0 to PC4) controls this divider. In parallel the output of the prescaler connects to an 11-bit divider(B). The 11-bit PC register (PC5 to PC15) controls this divider Dividing range: fOSC = (R+1) x fREF fVCO = [33 x A + (B + 1 - A) x 32] x fREF fVCO = (32 x B + A + 32) x fREF Important: For correct operation: A ≤ 32; B ≥ A Three State Phase Comparator The phase comparator generates a phase error signal according to phase difference between fSYN and fREF. This phase error signal drives the charge pump current generator. Charge Pump Current Generator This system generators signed pulses of current. The phase error signal decides the duration and polarity of those pulses. The current absolute values are programmable by A register for high current and B register for low current. Inlock Detector Switching the chargepump in low current mode can be done either via software or automatically by the inlock detector, by setting bit LDENA to "1". After reaching a phase difference of 10 - 40nsec and a delay of some times 1/fREF, the chargepump is forced in low current mode. A new PLL divider alternation by I2C-Bus will switch the chargepump in the high current mode. Few programmable phase errors (D0, D1) are available for inlock detection The count of detected inlock informations, to release the inlock signal is adjustable (D2, D3), to avoid a switching to low current during a frequency jump. Low Noise CMOS Op-amp An internal voltage divider at pin VREF2 connects the positive input of the low noise op-amp. The charge pump output connects the negative input. This internal amplifier in cooperation with external components can provide an active filter. The negative input is switchable to three input pins, to increase the flexibility in application. This feature allows two separate active filters for different applications. A logical "0" in the LPF register activates PIN LPFM, otherwise PIN LPAM is active. While the high current mode is activated LPHC is switched on. IF Counter Block The input signal for FM and AM upconversion is the same 10.7MHz IF level after limiter. The grade of integration is adjustable by eight different measuring cycle times. The tolerance of the accepted count value is adjustable, to reach an optimum compromise for search speed and precision of the evaluation. For the FM range the center frequency of the measured count value is adjustable in 32 steps, to get the possibility of fitting the IF-filter tolerance. In the AM upconversion range an IF frequency of 10.689MHz to 10.720MHz with 1kHz steps is available. 16/41 TDA7511 The IF-Counter Mode The IF counter works in 2 modes controlled by IFCM register. Sampling Timer A sampling timer to generate the gate signal for the main counter is build with a 14-bit programmable counter (IRC). In FM mode a 6.25kHz, in AM mode a 1kHz basically signal is generated. This is followed by an asynchronous divider to generate several sampling times. Intermediate Frequency Main Counter This counter is a 11 - 21-bit synchronous autoreload down counter. Five bits (CF) are programmable to have the possibility for an adjust to the frequency of the IF-filter. The counter length is automatic adjusted to the chosen sampling time and the counter mode (FM, AM-UPC). At the start the counter will be loaded with a defined value which is an equivalent to the divider value (tSample x fIF). If a correct frequency is applied to the IF counter frequency input at the end of the sampling time the main counter is changing its state from 0h to 1FFFFFh. This is detected by a control logic and an external search stop output is changing from LOW to HIGH. The frequency range inside which a successful count result is adjustable by the EW bits. tTIM = (IRC + 1) / fOSC tCNT = (CF + 1697) / fIF FM mode tCNT = (CF + 10689) / fIF AM up conversion mode Counter result succeeded: tTIM ≥ tCNT - tERR tTIM ≤ tCNT + tERR Counter result failed: tTIM > tCNT + tERR tTIM < tCNT - tERR tTIM = IF timer cycle time tCNT = IF counter cycle time tERR = discrimination window (controlled by the EW registers) The IF counter is only started by inlock information from the PLL part. It is enabled by software (IFENA). Adjustment of the Measurement Sequence Time 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. 17/41 TDA7511 1.8 I2C-Bus Interface The TDA 7511 supports the I2C-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 transmit or receive operations. Data Transition Data transition on the SDA line must only occur when the clock SCL is LOW. SDA transitions while SCL is HIGH will be interpreted as START or STOP condition. Start Condition A start condition is defined by a HIGH to LOW transition of the SDA line while SCL is at a stable HIGH level. This "START" condition must precede any command and initiate a data transfer onto the bus. The TDA 7511 continuously monitors the SDA and SCL lines for a valid START and will not response to any command if this condition has not been met. Stop Condition A STOP condition is defined by a LOW to HIGH transition of the SDA while the SCL line is at a stable HIGH level. This condition terminates the communication between the devices and forces the bus-interface of the TDA 7511 into the initial condition. Acknowledge Indicates a successful data transfer. The transmitter will release the bus after sending 8 bits of data. During the 9th clock cycle the receiver will pull the SDA line to LOW level to indicate it receive the eight bits of data. Data Transfer During data transfer the TDA 7511 samples the SDA line on the leading edge of the SCL clock. Therefore, for proper device operation the SDA line must be stable during the SCL LOW to HIGH transition. Device Addressing To start the communication between two devices, the bus master must initiate a start instruction sequence, followed by an eight bit word corresponding to the address of the device it is addressing. The most significant 6 bits of the slave address are the device type identifier. The TDA 7511 device type is fixed as "110001". The next significant bit is used to address a particular device of the previous defined type connected to the bus. The state of the hardwired PIN 41 defines the state of this address bit. So up to two devices could be connected on the same bus. When PIN 41 is connected to VCC2 the address bit “1” is selected. In this case the AM part doesn’t work. Otherwise the address bit “0” is selected (FM and AM is working). Therefor a double FM tuner concept is possible. The last bit of the start instruction defines the type of operation to be performed: - When set to "1", a read operation is selected - When set to "0", a write operation is selected The TDA 7511 connected to the bus will compare their own hardwired address with the slave address being transmitted, after detecting a START condition. After this comparison, the TDA 7511 will generate an "acknowledge" on the SDA line and will do either a read or a write operation according to the state of R/W bit. 18/41 TDA7511 Write Operation Following a START condition the master sends a slave address word with the R/W bit set to "0". The TDA 7511 will generate an "acknowledge" after this first transmission and will wait for a second word (the word address field). This 8-bit address field provides an access to any of the 32 internal addresses. Upon receipt of the word address the TDA 7511 slave device will respond with an "acknowledge". At this time, all the following words transmitted to the TDA 7511 will be considered as Data. The internal address will be automatically incremented. After each word receipt the TDA 7511 will answer with an "acknowledge". Read Operation IF the master sends a slave address word with the R/W bit set to "1", the TDA 7511 will transit one 8-bit data word. This data word includes the following informations: bit0 (ISS filter, 1 = ON, 0 = OFF) bit1 (ISS filter bandwidth, 1 = 80kHz, 0 = 120kHz) bit2 (MPOUT,1 = multipath present, 0 = no multipath) bit3 (1 = PLL is locked in , 0 = PLL is locked out). bit4 (fieldstrength indicator, 1 = lower as softmute threshold, 0 = higher as softmute threshold) bit5 (adjacent channel indicator, 1 = adjacent channel present, 0 = no adjacent channel) bit6 (deviation indicator, 1 = strong overdeviation present, 0 = no strong overdeviation) bit7 (deviation indicator, 1 = overdeviation present, 0 = no overdeviation) 2 Software Specification The interface protocol comprises: - start condition (S) - chip address byte - subaddress byte - sequence of data (N bytes + Acknowledge) - stop condition (P) Figure 1.
