5 / 32 page  RF RECEIVE SECTION CC2531 www.ti.com ........................................................................................................................................................................................ SWRS086 – SEPTEMBER 2009 Measured on Texas Instruments CC2530 EM reference design with TA = 25°C, VDD = 3 V, and fc = 2440 MHz, unless otherwise noted. Bold limits apply over the entire operating range, TA = –40°C to 125°C, VDD = 2 V to 3.6 V, and fc = 2394 MHz to 2507 MHz. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT PER = 1%, as specified by [1] –97 –92 Receiver sensitivity dBm [1] requires –85 dBm –88 PER = 1%, as specified by [1] Saturation (maximum input level) 10 dBm [1] requires –20 dBm Wanted signal –82 dBm, adjacent modulated channel at Adjacent-channel rejection, 5-MHz 5 MHz, PER = 1 %, as specified by [1]. 49 dB channel spacing [1] requires 0 dB Wanted signal –82 dBm, adjacent modulated channel at Adjacent-channel rejection, –5-MHz –5 MHz, PER = 1 %, as specified by [1]. 49 dB channel spacing [1] requires 0 dB Wanted signal –82 dBm, adjacent modulated channel at Alternate-channel rejection, 10-MHz 10 MHz, PER = 1%, as specified by [1] 57 dB channel spacing [1] requires 30 dB Wanted signal –82 dBm, adjacent modulated channel at Alternate-channel rejection, –10-MHz –10 MHz, PER = 1 %, as specified by [1] 57 dB channel spacing [1] requires 30 dB Channel rejection Wanted signal at –82 dBm. Undesired signal is an IEEE 802.15.4 modulated channel, stepped through all channels dB ≥ 20 MHz 57 from 2405 to 2480 MHz. Signal level for PER = 1%. 57 ≤ –20 MHz Wanted signal at –82 dBm. Undesired signal is 802.15.4 Co-channel rejection modulated at the same frequency as the desired signal. Signal –3 dB level for PER = 1%. Blocking/desensitization 5 MHz from band edge Wanted signal 3 dB above the sensitivity level, CW jammer, –33 10 MHz from band edge PER = 1%. Measured according to EN 300 440 class 2. –33 20 MHz from band edge –32 dBm 50 MHz from band edge –31 –5 MHz from band edge –35 –10 MHz from band edge –35 –20 MHz from band edge –34 –50 MHz from band edge –34 Spurious emission. Only largest spurious Conducted measurement with a 50- Ω single-ended load. emission stated within each band. Suitable for systems targeting compliance with EN 300 328, dBm 30 MHz–1000 MHz ≤80 EN 300 440, FCC CFR47 Part 15 and ARIB STD-T-66. 1 GHz–12.75 GHz –57 Frequency error tolerance(1) [1] requires minimum 80 ppm ±150 ppm Symbol rate error tolerance(2) [1] requires minimum 80 ppm ±1000 ppm Sensitivity impact of USB operation Measured on CC2531 Dongle reference design with CDC bulk 0.5 dB transfer to PC at maximum speed.
