NOISE CHARACTERISTICS

Normalized Phase Noise Floor5

dBc/Hz typ

1 Operating temperature range (B version) is −40°C to +85°C.

2 AC coupling ensures AV

DD/2 bias. See Figure 13 for typical circuit.

3 Guaranteed by design. Characterized to ensure compliance.

4 T

A = 25°C; AVDD = DVDD = 3 V; N = 64; RFIN = 7.5 GHz.

5 The synthesizer phase noise floor is estimated by measuring the in-band phase noise at the output of the VCO, PN

TOT, and subtracting 20logN (where N is the N divider

value) and 10logFPFD. PNSYNTH = PNTOT − 10logFPFD − 20logN. The in-band phase noise (PNTOT) is measured using the HP8562E Spectrum Analyzer from Agilent.
