Note 1:
All power levels are referred to 75
and 0 dBm = 109 dB
μ
V
Any two tones within RF operating range at 94 dB
μ
V beating within band, with output load as in Figure 4
Port powers up in high impedance state
Note 2:
Note 3:
Note 4:
To maximise phase noise the tuning range should be minimised and Q of resonator maximised. The application as in Figure
18 has a tuning range of 200 MHz.
Note 5:
If the BUFREF output is not used it should be left open circuit or connected to Vccd and disabled by setting RE = '0'.
