The MAX2160/EBG uses a 2-wire I
interface consisting of a serial-data line (SDA) and a
serial-clock line (SCL). SDA and SCL facilitate bidirec-
tional communication between the MAX2160/EBG and
the master at clock frequencies up to 400kHz. The
master initiates a data transfer on the bus and gener-
ates the SCL signal to permit data transfer. The
MAX2160/EBG behave as a slave device that transfers
and receives data to and from the master. SDA and
SCL must be pulled high with external pullup resistors
(1kΩ or greater) for proper bus operation.
One bit is transferred during each SCL clock cycle. A
minimum of nine clock cycles is required to transfer a
byte in or out of the MAX2160/EBG (8 bits and an
ACK/NACK). The data on SDA must remain stable dur-
ing the high period of the SCL clock pulse. Changes in
SDA while SCL is high and stable are considered con-

Reflect the charge-pump current setting. See Table 3 for CP[1:0] definition.
Logic-high indicates power has been cycled, but the device has the default programming. A STOP
condition while in read mode resets this bit.
Indicates whether VCO automatic selection was successful.
0 = indicates the autoselect function is disabled or unsuccessful VCO selection
1 = indicates successful VCO automatic selection
Status indicator for the autoselect function.
0 = indicates the autoselect function is active
1 = indicates the autoselect process is inactive
Indicate which VCO has been selected by either the autoselect state machine or by manual
selection when the VAS state machine is disabled. See Table 4 for VCO[1:0] definition.
Indicate which sub-band of a particular VCO has been selected by either the autoselect state
machine or by manual selection when the VAS state machine is disabled. See Table 4 for VSB[2:0]
definition.
Indicate the 3-bit ADC conversion of the VCO tuning voltage (VTUNE).

C-compatible serial
trol signals (see the START and STOP Conditions sec-
tion). Both SDA and SCL remain high when the bus is
not busy.
The master initiates a transmission with a START condi-
tion (S), which is a high-to-low transition on SDA while
SCL is high. The master terminates a transmission with
a STOP condition (P), which is a low-to-high transition
on SDA while SCL is high.
Data transfers are framed with an acknowledge bit
(ACK) or a not-acknowledge bit (NACK). Both the mas-
ter and the MAX2160/EBG (slave) generate acknowl-
edge bits. To generate an acknowledge, the receiving
device must pull SDA low before the rising edge of the
acknowledge-related clock pulse (ninth pulse) and
keep it low during the high period of the clock pulse.
