MAX2769B
Universal GPS Receiver
Preconfigured Device States
When a serial interface is not available, the device can
be used in preconfigured states that don’t require pro-
gramming through the serial interface. Connecting the
PGM pin to logic-high and SCLK, SDATA, and CS pins
to either logic-high or low sets the device in one of the
preconfigured states according to Table 3 .
Power-On Reset (POR)
The MAX2769B incorporates power-on reset circuitry to
ensure that register settings are loaded upon power-up.
To ensure proper operation, the rising edge of PGM must
occur no sooner than when V CC_ reaches 90% of its final
nominal value; see Figure 4 for details.
Table 3. Preconfigured Device States
Serial Interface, Address, and
Bit Assignments
A serial interface is used to program the MAX2769B for
configuring the different operating modes.
The serial interface is controlled by three signals: SCLK
(serial clock), CS (chip select), and SDATA (serial data).
The control of the PLL, AGC, test, and block selection
is performed through the serial-interface bus from the
baseband controller. A 32-bit word, with the MSB (D27)
being sent first, is clocked into a serial shift register when
the chip-select signal is asserted low. The timing of the
interface signals is shown in Figure 5 and Table 4 along
with typical values for setup and hold time requirements.
