PRODUCTION DATA.
| PARAMETER | TYP | UNIT | CONDITION | |
|---|---|---|---|---|
| Phase noise, 402 to 470 MHz | At 12.5 kHz offset from carrier | –79 | 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 | –80 | dBc/Hz | ||
| At 50 kHz offset from carrier | –87 | dBc/Hz | ||
| At 100 kHz offset from carrier | –100 | dBc/Hz | ||
| At 1 MHz offset from carrier | –105 | dBc/Hz | ||
| Phase noise, 804 to 930 MHz | At 12.5 kHz offset from carrier | –73 | 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 | –74 | dBc/Hz | ||
| At 50 kHz offset from carrier | –81 | dBc/Hz | ||
| At 100 kHz offset from carrier | –94 | dBc/Hz | ||
| At 1 MHz offset from carrier | –111 | dBc/Hz | ||
| PLL loop filter bandwidth | Loop filter 2, up to 19.2 kBaud | 15 | kHz | After PLL and VCO calibration.
The PLL loop bandwidth is programmable. See Table 5-12 for loop filter component values. |
| Loop filter 3, up to 38.4 kBaud | 30.5 | kHz | ||
| PLL lock time (RX / TX turn time) | Loop filter 2, up to 19.2 kBaud | 140 | µs | 307.2 kHz frequency step to RF frequency within ±10 kHz, ±15 kHz, ±50 kHz settling accuracy for loop filter 2, 3 and 5 respectively. Depends on loop filter component values and PLL_BW register setting. See Table 5-13 for more details. |
| Loop filter 3, up to 38.4 kBaud | 75 | µs | ||
| Loop filter 5, up to 153.6 kBaud | 14 | µs | ||
| PLL turn-on time.
From power down mode with crystal oscillator running. |
Loop filter 2, up to 19.2 kBaud | 1300 | µs | Time from writing to registers to RF frequency within ±10 kHz, ±15 kHz, ±50 kHz settling accuracy for loop filter 2, 3 and 5 respectively. Depends on loop filter component values and PLL_BW register setting. See Table 5-12 for more details. |
| Loop filter 3, up to 38.4 kBaud | 1080 | µs | ||
