79 / 99 page  CC2500 SWRS040C Page 79 of 89 0x22: FREND0 – Front End TX configuration Bit Field Name Reset R/W Description 7:6 Reserved R0 5:4 LODIV_BUF_CURRENT_TX[1:0] 1 (01) R/W Adjusts current TX LO buffer (input to PA). The value to use in this field is given by the SmartRF Studio software [5]. 3 Reserved R0 2:0 PA_POWER[2:0] 0 (000) R/W Selects PA power setting. This value is an index to the PATABLE. In OOK mode, this selects the PATABLE index to use when transmitting a ‘1’. PATABLE index zero is used in OOK when transmitting a ‘0’. 0x23: FSCAL3 – Frequency Synthesizer Calibration Bit Field Name Reset R/W Description 7:6 FSCAL3[7:6] 2 (10) R/W Frequency synthesizer calibration configuration. The value to write in this register before calibration is given by the SmartRF Studio software [5]. 5:4 CHP_CURR_CAL_EN[1:0] 2 (10) R/W Disable charge pump calibration stage when 0 3:0 FSCAL3[3:0] 9 (1001) R/W Frequency synthesizer calibration result register. Digital bit vector defining the charge pump output current, on an exponential scale: IOUT=I0·2 FSCAL3[3:0]/4 Fast frequency hopping without calibration for each hop can be done by calibrating upfront for each frequency and saving the resulting FSCAL3, FSCAL2 and FSCAL1 register values. Between each frequency hop, calibration can be replaced by writing the FSCAL3, FSCAL2 and FSCAL1 register values corresponding to the next RF frequency. 0x24: FSCAL2 – Frequency Synthesizer Calibration Bit Field Name Reset R/W Description 7:6 Reserved R0 5 VCO_CORE_H_EN 0 R/W Choose high (1) / low (0) VCO 4:0 FSCAL2[4:0] 10 (0x0A) R/W Frequency synthesizer calibration result register. VCO current calibration result and override value Fast frequency hopping without calibration for each hop can be done by calibrating upfront for each frequency and saving the resulting FSCAL3, FSCAL2 and FSCAL1 register values. Between each frequency hop, calibration can be replaced by writing the FSCAL3, FSCAL2 and FSCAL1 register values corresponding to the next RF frequency. |
