trf371135 www.ti.com slws220a ? february 2010 ? revised march 2010 application information gain control the trf371135 integrates a baseband programmable-gain amplifier (pga) that provides 24 db of gain range with 1-db steps. the pga gain is controlled through spi by a 5-bit word (register 1 bits < 12,16 > ). alternatively, the pga can be programmed by a combination of five bits programmed through the spi and three parallel external bits (pins gain_b2, gain_b1, gain_b0). the external bits are used to reduce the pga setting quickly without having to reprogram the spi registers. the fast gain control multiplier bit (register 1 bit 28) sets the step size of each bit to either 1 db or 2 db. this allows a fast gain reduction of 0 db to 7 db in 1-db steps or 0 db to 14 db in 2-db steps. the pga gain control word (bbgain < 0,4 > ) can be programmed to a setting between 0 and 24. this word is the spi programmed gain (register 1 bits < 12,16 > ) minus the parallel external 3 bits as shown in figure 56 . note that the pga gain setting rails at 0 and does not go any lower. typical applications set the nominal pga gain setting to 17 and use the fast-gain control bits to protect the analog-to-digital converter in the event of a strong input jammer signal. figure 56. pga gain control word for example, if a pga gain setting of 19 is desired, then the spi can be programmed directly to a value of 19. alternatively, the spi gain register can be programmed to 24 and the parallel external bits set to 101 (binary) corresponding to 5-db reduction. automated dc offset calibration the trf371135 provides an automatic calibration procedure for adjusting the dc offset in the baseband i/q paths. the internal calibration requires a clock in order to function. the trf371135 can use the internal relaxation oscillator or the external spi clock. using the internal oscillator is the preferred method, which is selected by setting the cal_clk_sel (register 2, bit 28) to 1. the internal oscillator frequency is set through the osc_trim bits (register 2, bits < 29,31 > ). the frequency of the oscillator is detailed in table 7 ; however, it is expected the actual frequency of operation can vary plus or minus 35% due to process variations. the oscillator frequency can be monitored on the readback pin when the osc_test register (register 1, bit 29) is set to 1. table 7. internal oscillator frequency control osc_trim < 2 > osc_trim < 1 > osc_trim < 0 > frequency 0 0 0 300 khz 0 0 1 500 khz 0 1 0 700 khz 0 1 1 900 khz 1 0 0 1.1 mhz 1 0 1 1.3 mhz 1 1 0 1.5 mhz 1 1 1 1.8 mhz copyright ? 2010, texas instruments incorporated submit documentation feedback 45 product folder link(s): trf371135 spi x (x1, x2) fast gain select + composite pga setting (min: 0, max 24) gain_b2 gain_b1 gain_b0 b0386-01
trf371135 slws220a ? february 2010 ? revised march 2010 www.ti.com the default setting of these registers corresponds to a 900-khz oscillator frequency. this is sufficient for autocalibration; modification is not required except for faster calibration convergence. the output full-scale range of the internal dc offset correction dacs is programmable (idet_b < 0,1 > , register 2 bits < 22,23 > ). the range is shown in table 8 . table 8. dc offset correction dac programmable range idet_b0 idet_b1 full scale 0 0 50 a 0 1 100 a 1 0 150 a 1 1 200 a the i- and q-channel output maximum dc offset correction range can be calculated by multiplying the values in the table by the baseband pga gain. the lsb of the digital correction is dependent on the programmed maximum correction range. for optimum resolution and best correction, the dc offset dac range should be set to 50 a with the pga gain set for the nominal condition. the dc offset correction dac output is affected by a change in the pga gain, but if the initial calibration yields optimum results, then the adjustment of the pga gain during normal operation does not significantly impair the dc offset balance. for example, if the optimized calibration yields a dc offset balance of 2 mv at a gain setting of 17, then the dc offset maintains less than 10 mv balance as the gain is adjusted 7 db. the dc offset correction dacs are programmed from the internal registers when the cal_sel bit (register 2, bit 24) is set to 1. at start-up, the internal registers are loaded at half-scale, corresponding to a decimal value of 128. the auto-cal is initiated by toggling the en_autocal bit (register 2, bit 5) to 1. when the calibration is over, this bit is automatically reset to 0. during calibration, the rf local oscillator must be applied. the dc offset dac state is stored in the internal registers and maintained as long as the power supply is kept on or until a new calibration is started. the required clock speed for the optimum calibration is determined by the internal detector behavior (integration bandwidth, gain, sensitivity). the input bandwidth of the detector can be adjusted by changing the cutoff frequency of the rc low-pass filter in front of the detector (register 1, bits 25 ? 26). en_flt_b0 controls the resistor (bypass = 1) and en_flt_b1 controls the capacitor (bypass = 1). the typical 3-db cutoff frequencies of the detector bandwidth are summarized in table 9 . the speed of the clock can be slowed down by selecting a clock divider ratio (register 2, bits 25 ? 27). table 9. detector bandwidth settings en_flt_b1 en_flt_b0 typical 3-db cutoff frequency notes x 0 10 mhz maximum bandwidth, bypass r, c 0 1 10 khz enable r 1 1 1 khz minimum bandwidth, enable r, c the detector has more averaging time with a slower clock; hence, it is desirable to slow down the clock speed for a given condition to achieve optimum results. for example, if there is no rf present on the rf input port, the detection filter can be left wide (10 mhz) and the clock divider can be left at div-by-128. the autocalibration yields a dc offset balance between the differential baseband output ports (i and q) that is less than 15 mv. some minor improvement may be obtained by increasing the averaging of the detector by increasing the clock divider up to 256 or 1024. on the other hand, if there is a modulated rf signal present at the input port, it is desirable to reduce the detector bandwidth to filter out most of the modulated signal. the detector bandwidth can be set to a 1-khz corner frequency. with the modulated signal present and with the detection bandwidth reduced, additional averaging is required to get the optimum results. a clock divider setting of 1024 yields optimum results. of course, an increase in the averaging is possible by increasing the clock divider at the expense of longer converging time. the convergence time can be calculated by the following: (1) 46 submit documentation feedback copyright ? 2010, texas instruments incorporated product folder link(s): trf371135 c (auto_cal_clk_cycles) (clk_divider) = osc_freq t
