default values. A stop condition while in read mode
resets this bit.
Bits ADC(2), ADC(1), and ADC(0) represent a 3-bit
ADC conversion of the VCO tune voltage used for VCO
and charge pump current selection and calibration.
Bits F(6)–F(0) are a 7-bit representation of the LPF DAC
current.

This is the standard I 2 C protocol. The write/read/
address bytes are dependent on the states of pins
AS0/AS1/AS2.
Write Operation
The first byte is the device address plus the direction
bit (R/ W = 0).
The second byte contains the internal address com-
mand of the first address to be accessed.
The third byte is written to the internal register directed
by the command address byte.
The following bytes (if any) are written into successive
internal registers.

Selection (Byte 04)
The transfer lasts until stop conditions are encountered.
The MAX2116 acknowledges every byte transfer.

When an address is sent, the MAX2116 sends back
first the status byte and then the I/Q DAC byte.
Example: Write registers 0 to 3 with 0E, D8, 26 (Table 9).
Example: Read from status registers. Sending an ACK
terminates slave transmit mode (Table 10).
BYTE 05 (default = 1F)
Bits D(2), D(1), and D(0) control diagnostic features
(Table 7).
Bits G(4)–G(0) controls the gain of the baseband VGA.
The BB gain is minimum at 11111 and the BB gain is
maximum at 00000. Default is minimum gain setting of
11111 (Table 8).
