NOTES
1Analog Input Range is a function of input frequency. See ac specifications for 70 MHz–250 MHz inputs.
2Analog Input Impedance is a function of input frequency. See ac specifications for 70 MHz–450 MHz inputs.
3Six dB of digital hysteresis is used to eliminate level uncertainty at the RSSI threshold points due to noise and amplitude variations.
4Encode inputs should be ac-coupled and driven differentially. See Encoding the AD6600 for details.
5A_SEL and B_SEL should be tied directly to ground or AVCC.
6Maximum power consumption is computed as maximum current at nominal supplies.
Specifications subject to change without notice.
