PRODUCTION DATA.
PARAMETER | TYP | UNIT | CONDITION | |
---|---|---|---|---|
Phase noise,
402 to 470 MHz 12.5 kHz channel spacing |
At 12.5 kHz offset from carrier | –90 | dBc/Hz | Unmodulated carrier.
Measured using loop filter components given in Table 6-2. The phase noise will be higher for larger PLL loop filter bandwidth. |
At 25 kHz offset from carrier | –100 | dBc/Hz | ||
At 50 kHz offset from carrier | –105 | dBc/Hz | ||
At 100 kHz offset from carrier | –110 | dBc/Hz | ||
At 1 MHz offset from carrier | –114 | dBc/Hz | ||
Phase noise,
804 to 930 MHz 25 kHz channel spacing |
At 12.5 kHz offset from carrier | –85 | dBc/Hz | Unmodulated carrier.
Measured using loop filter components given in Table 6-2. The phase noise will be higher for larger PLL loop filter bandwidth. |
At 25 kHz offset from carrier | –95 | dBc/Hz | ||
At 50 kHz offset from carrier | –101 | dBc/Hz | ||
At 100 kHz offset from carrier | –109 | dBc/Hz | ||
At 1 MHz offset from carrier | –118 | dBc/Hz | ||
PLL loop bandwidth | 12.5 kHz channel spacing, 433 MHz | 2.7 | kHz | After PLL and VCO calibration. The PLL loop bandwidth is programmable. |
25 kHz channel spacing, 868 MHz | 8.3 | kHz | ||
PLL lock time
(RX / TX turn time) |
12.5 kHz channel spacing, 433 MHz | 900 | µs | 307.2 kHz frequency step to RF frequency within ±10% of channel spacing. Depends on loop filter component values and PLL_BW register setting. See Table 5-13 for more details. |
25 kHz channel spacing, 868 MHz | 640 | µs | ||
500 kHz channel spacing | 14 | µs | ||
PLL turn-on time.
From power down mode with crystal oscillator running. |
12.5 kHz channel spacing, 433 MHz | 3.2 | ms | Time from writing to registers to RF frequency within ±10% of channel spacing. Depends on loop filter component values and PLL_BW register setting. See Table 5-12 for more details. |
25 kHz channel spacing, 868 MHz | 2.5 | ms | ||
500 kHz channel spacing | 700 | µs |
