AC ELECTRICAL CHARACTERISTICS (continued)

(MAX2165 EV kit, VCC = +2.75V to +3.3V, VRF_AGC = VBB_AGC = 2.3V (maximum gain), VOUT = 1VP-P, 75Ω system impedance, reg-

isters set according to the specified default register conditions, TA = -40°C to +85°C, unless otherwise noted. Typical values are at

VCC = +2.85V, TA = +25°C, unless otherwise noted.) (Note 1)

Min and max limits are guaranteed by test at TA = +25°C and are guaranteed by design and characterization at TA =

-40°C and +85°C. The default register settings are not production tested. Load registers no sooner than 100µs after

power-up.

Notch filter must be disabled by programming the TF_NTCH[3:0] bits to 1111 to enable operation up to 832MHz. Under

extreme conditions, the part can experience up to 3dB degradation in sensitivity and intermodulation distortion.

Guaranteed by design and characterization over the specified operating conditions. Not production tested.

UHF tones resulting in f1 - f2 beat frequency within the baseband output. Two tones at 350MHz and 1133MHz

with IM2 measured at 783MHz.

Two tones converted to 5.25MHz and 10.75MHz, IM3 measured at 250kHz.

A desired signal at PDESIRED = -78dBm is injected and downconverted to 3.75MHz. A blocker tone is injected at 10MHz

higher in frequency. Specified level is blocker power at which desired output signal compresses by 1dB. TA = +25°C.

A single blocker at -7dBm with a bandwidth of less than 4MHz is injected at 880MHz with the receiver tuned to 783MHz

and set to maximum gain.

VCO locked to within 100Hz of the Rx frequency. Wake-up initiated by toggling the SHDN pin from low to high and con-

necting the STBY pin to ground.

Applies to continuous DC correction operation (DVB-T mode). In DVB-H mode, optional correction hold feature allows

quasi-DC-coupling.

Depends on 7MHz/8MHz bandwidth mode.

Equivalent to video carrier in upper adjacent channel. TA = +25°C.

Equivalent to fNYQUIST - 3.8MHz for 18.3MHz sampling rate baseband DAC.

Total frequency resolution is fREF / 220, or approximately 20Hz with a 20MHz reference frequency.

unless otherwise noted.)
