请参考 PDF 数据表获取器件具体的封装图。
The starting point is the typical total current consumption of 250 mA: 100-MHz input frequency, OSCin doubler bypassed, Pre-R divider bypassed, multiplier bypassed, post-R divider bypassed, 100-MHz phase detector frequency, 0.468-mA charge pump current, channel divider off, one output on, 6000-MHz output frequency, 50-Ω output pullup, 0-dBm output power (differential). To understand current consumption changes due to engaging different functional blocks , refer to Table 8-3.
| ACTION | STEPS | PROGRAMMING | INCREASE IN CURRENT (mA) |
|---|---|---|---|
| Use input signal path | Enable OSCin doubler | OSC_2X = 1 | 7 |
| Enable multiplier | MULT = 3,4,5, or 6 | 10 | |
| Add an output | Route VCO to output B | VCO_DISTB_PD = 0 | 8 |
| Enable output B buffer | OUTB_PD = 0 | 54 | |
| Increase output power from 0 to +10dBm (differential) | Set highest output buffer current | OUTA_POW = 63 | 53 |
| Use channel divider | Route channel divider to output | CHDIV_DISTA_EN = 1 | 5 |
| Enable channel divider | CHDIV_EN = 1 | 18 | |
| Enable chdiv_seg1 | CHDIV_SEG1_EN = 1 | 2 | |
| Enable chdiv_seg2 | CHDIV_SEG2_EN = 1 | 5 | |
| Enable chdiv_seg3 | CHDIV_SEG3_EN = 1 | 5 | |
| Using VCO doubler | Enable VCO doubler | VCO2X_EN | 16 |
