The values of R13 is determined by the set-up proce- dure. See Application Note. 2. The value of C9 is determined by the output data rate. Use 2nF for 512bps, 1nF for 1200bps and 470pF for 2400bps. 3. L2 is used in the Audio AGC circuit (see Fig. 6). For the characteristics of the Audio AGC current source see Fig.7. If the audio AGC is not required then the current source (Pin 28) may be disabled by connecting Pin 9 (TCADJ) to VR (Pin 6) and by connecting Pin 28 (IAGCOUT) to Vcc1, (R18). The voltage at Pin 8 may still be used as an RSSI. R9, C8, C14, C19, R17 and D1 may then be omitted. See Fig.6 for AGC component values. 4. L1and C26 form the low noise matching network for the RF amplifier. The values given are for the RF amplifier specified in the Applications Circuit with no Audio AGC connected. i.e. R17 and D1 omitted. 5. Suggested diode for use with the Audio AGC circuit (see Fig.6) (D1 is not included on the general demon- stration circuit). 6. The value of R11 is dependent on the data output load. R11 should allow sufficient current to drive the data output load. |
