Universal GPS Receiver

AC ELECTRICAL CHARACTERISTICS (continued)

(MAX2769 EV kit, V

= 2.7V to 3.3V, T = -40°C to +85°C, PGM = GND. Registers are set to the default power-up states. LNA input

is driven from a 50Ω 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 10kΩ || 7.5pF on each pin. Typical values

are at V

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

Note 1: MAX2769 is production tested at T = +25°C. All min/max specifications are guaranteed by design and characterization

from -40°C to +85°C, unless otherwise noted. Default register settings are not production tested or guaranteed. User must

program the registers upon power-up.

Note 2: Default, low-NF mode of the IC. LNA choice is gated by the ANT_FLAG signal. In the normal mode of operation without an

active antenna, LNA1 is active. If an active antenna is connected and ANT_FLAG switches to 1, LNA1 is automatically

disabled and LNA2 becomes active. PLL is in an integer-N mode with f

= f / 16 = 1.023MHz and I = 0.5mA. The

TCXO

COMP

complex IF filter is configured as a 5th-order Butterworth filter with a center frequency of 4MHz and bandwidth of 2.5MHz. Output

data is in a 2-bit sign/magnitude format at CMOS logic levels in the I channel only.

Note 3: The LNA output connects to the mixer input without a SAW filter between them.

Note 4: Two tones are located at 12MHz and 24MHz offset frequencies from the GPS center frequency of 1575.42MHz

at -60dBm/tone. Passive pole at the mixer output is programmed to be 13MHz.

Note 5: Measured from the LNA input to the LNA output. Two tones are located at 12MHz and 24MHz offset frequencies from the

GPS center frequency of 1575.42MHz at -60dBm per tone.
