Start-up of 16-MHz RCOSC Digital regulator off, 16-MHz RCOSC and 32-MHz crystal Power mode 2 or 3 → Active 120 μs oscillator off. Start-up of regulator and 16-MHz RCOSC Crystal ESR = 16 Ω. Initially running on 16-MHz RCOSC, 410 μs with 32-MHz XOSC OFF Active → TX or RX With 32-MHz XOSC initially on 160 μs RX/TX turnaround 150 μs RADIO PART RF frequency range Programmable in 2-MHz steps 2402 2480 MHz Data rate and modulation format 1 Mbps, GFSK, 250 kHz deviation RF RECEIVE SECTION Measured on Texas Instruments CC2540 EM reference design with TA = 25°C, VDD = 3 V, fc = 2440 MHz 1 Mbps, GFSK, 250-kHz deviation, Bluetooth low energy mode, and 0.1% BER (1) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Receiver sensitivity(2) High-gain mode –93 dBm Receiver sensitivity(2) Standard mode –87 dBm Saturation(3) 6 dBm Co-channel rejection(3) –5 dB Adjacent-channel rejection(3) ±1 MHz –5 dB Alternate-channel rejection(3) ±2 MHz 30 dB Blocking(3) –30 dBm Frequency error tolerance(4) Including both initial tolerance and drift –250 250 kHz Symbol rate error tolerance(5) –80 80 ppm Conducted measurement with a 50- Ω single-ended load. Spurious emission. Only largest spurious Complies with EN 300 328, EN 300 440 class 2, FCC CFR47, –75 dBm emission stated within each band. Part 15 and ARIB STD-T-66 RX mode, standard mode, no peripherals active, low MCU 19.6 activity, MCU at 250 kHz Current consumption mA RX mode, high-gain mode, no peripherals active, low MCU 22.1 activity, MCU at 250 kHz (1) 0.1% BER maps to 30.8% PER (2) The receiver sensitivity setting is programmable using a TI BLE stack vendor-specific API command. The default value is standard mode. (3) Results based on standard gain mode (4) Difference between center frequency of the received RF signal and local oscillator frequency (5) Difference between incoming symbol rate and the internally generated symbol rate Copyright © 2010–2011, Texas Instruments Incorporated 5 |
