11 / 91 page  Not Recommended for New Designs NRND CC1021 www.ti.com SWRS045D – JANUARY 2006 – REVISED JANUARY 2015 RF Receive (continued) All measurements were performed using the two-layer PCB CC1020EMX reference design. See Figure 6-1. The electrical specifications given for 868 MHz are also applicable for 902 to 928 MHz. TA = 25°C, AVDD = DVDD = 3.0 V, fC = 14.7456 MHz if nothing else stated. PARAMETER MIN TYP MAX UNIT CONDITION 433 MHz –14 dB Using application circuit matching Matched input network. See Section 5.11 for impedance, S11 868 MHz –12 dB details. 433 MHz 39 – j14 Ω Using application circuit matching Matched input network. See Section 5.11 for impedance 868 MHz 32 – j10 Ω details. The maximum bit rate offset tolerated by the bit synchronization Bit synchronization offset 8000 ppm circuit for 6 dB degradation (synchronous modes only) NRZ mode 4 Baud Time from clocking the data on the Data latency transmitter DIO pin until data is Manchester mode 8 Baud available on receiver DIO pin 4.6 RSSI / Carrier Sense All measurements were performed using the two-layer PCB CC1020EMX reference design. See Figure 6-1. The electrical specifications given for 868 MHz are also applicable for 902 to 928 MHz. TA = 25°C, AVDD = DVDD = 3.0 V, fC = 14.7456 MHz if nothing else stated. PARAMETER TYP UNIT CONDITION RSSI dynamic range 55 dB See Section 5.9.5 for details. RSSI accuracy ±3 dB See Section 5.9.5 for details. RSSI linearity ±1 dB 51.2 kHz channel filter BW 730 µs Shorter RSSI attach times can be traded for lower RSSI accuracy. See 102.4 kHz channel filter BW 380 µs Section 5.9.5 for details. RSSI attach time Shorter RSSI attach times can also be traded for reduced sensitivity and 307.2 kHz channel filter BW 140 µs selectivity by increasing the receiver channel filter bandwidth. Carrier sense programmable range 40 dB Accuracy is as for RSSI ±100 kHz –57 dBm At carrier sense level –98 dBm, CW 102.4 kHz channel filter BW, jammer at ±100 kHz and ±200 kHz 433 MHz ±200 kHz –44 dBm Carrier sense offset. ±100 kHz –60 dBm at ±100 kHz and Carrier sense is measured by applying a 102.4 kHz channel filter BW, ±200 kHz offset signal at ±100 kHz and ±200 kHz offset 868 MHz and observe at which level carrier sense ±200 kHz –44 dBm is indicated.
