MAX2769B
Universal GPS Receiver
Typical Operating Characteristics (continued)
(MAX2769B EV kit, V CC_ = 2.7V to 3.3V, T A = -40°C to +85 N C, PGM = Ground. Registers are set to the default power-up states. LNA
input is driven from a 50 I source. All RF measurements are done in the analog output mode with ADC bypassed. PGA gain is set
to 51dB gain by serial-interface word GAININ = 111010. Maximum IF output load is not to exceed 10k I ||7.5pF on each pin. Typical
values are at V CC_ = 2.85V and T A = +25 N C, unless otherwise noted.)
