Modes of Operation
The modes of operation for the MAX2830 are shutdown,
standby, transmit, receive, transmitter calibration, and
receiver calibration. See Table 32 for a summary of the
modes of operation. The logic-input pins, SHDN (pin 12)
and RXTX (pin 48), control the various modes.
Shutdown Mode
The MAX2830 features a low-power shutdown mode
that disables all circuit blocks, except the serial-inter-
face and internal registers, allowing the registers to be
30
loaded and values maintained, as long as V CC is
applied. Set SHDN and RXTX logic-low to place the
device in shutdown mode. After a supply voltage ramp
up, supply current in shutdown mode could be high.
Program the default value to SPI register 0 to eliminate
high shutdown current.
Standby Mode
The standby mode is used to enable the frequency syn-
thesizer block while the rest of the device is powered
down. In this mode, the PLL, VCO, and LO generators
