Pin Description (continued)
Table 1. Operating Modes
Note 4: PA_BIAS pins may be kept active in nontransmit mode(s) by SPI programming.
Note 5: CLKOUT signal is active independent of SPI, and is only dependent on the ENABLE pin.
Detailed Description
Modes of Operation
The modes of operation for the MAX2850 are shutdown,
clockout, standby, receive, transmit, transmitter calibra-
tion, RF loopback, and baseband loopback. See Table 1
for a summary of the modes of operation. The logic input
pin ENABLE (pin 55) and SPI Main address 0 D4:D2
control the various modes.
Shutdown Mode
The MAX2850 features a low-power shutdown mode. All
circuit blocks are powered down, except the 4-wire serial
bus and its internal programmable registers.
