Interferer is CW, and desired is modulated with 2.4 kbps F = 1.2 kHz GFSK with BT = 0.5, RX channel BW = 4.8 kHz, channel spacing = 12.5 kHz –69 –59 dB 1-Ch Offset Selectivity, 450 MHz3 C/I1-CH –60 –50 dB 1-Ch Offset Selectivity, 868 / 915 MHz3 C/I1-CH –55 –45 dB Blocking 1 MHz Offset 1MBLOCK Desired Ref Signal 3 dB above sensitiv- ity, BER = 0.1%. Interferer is CW, and desired is modulated with 2.4 kbps, F = 1.2 kHz GFSK with BT = 0.5, RX channel BW = 4.8 kHz –79 –68 dB Blocking 8 MHz Offset 8MBLOCK –86 –75 dB Table 3. Receiver AC Electrical Characteristics1,2 (Continued) Parameter Symbol Test Condition Min Typ Max Unit Notes: 1. All minimum and maximum values are guaranteed across the recommended operating conditions of supply voltage and from –40 to +85 °C unless otherwise stated. All typical values apply at VDD = 3.3 V and 25 °C unless otherwise stated. 2. For PER tests, 48 preamble symbols, 4 byte sync word, 10 byte payload and CRC-32 was used. 3. Measured over 50000 bits using PN9 data sequence and data and clock on GPIOs. Sensitivity is expected to be better if reading data from packet handler FIFO especially at higher data rates. 4. Conducted emissions measured on RF evaluation boards. |
