Electrical Characteristics

(4) (Continued)

fRF = 490MHz, fXTAL = 16MHz, MICRF507 Development Board, Modulation type = closed-loop VCO modulation, Sync_en bit = 1,

VDD = 2.5V; TA = 25°C, the term “bit rate” refers to encoded bit rate throughout the EC table (see Figure 24), bold values indicate

–40°C< TA < +85°C, unless noted.
