The MAX2981 interfaces to the MAX2982/MAX2986
digital baseband IC using a bidirectional bus to pass
the digital data to and from the DAC and ADC.
Handshake lines help accomplish the data transfer and
operation of the MAX2981. The application circuit dia-
gram of Figure 4 shows the connection of the MAX2981
to the MAX2982/MAX2986 digital baseband chip.

A properly designed PCB is an essential part of any
high-speed circuit. Use controlled-impedance lines on
all frequency inputs and outputs. Use low-inductance
connections to ground on all ground pins and wherever
the components are connected to ground. Place
decoupling capacitors close to all V
For proper operation, connect the metal exposed pad-
dle at the back of the IC to the PCB ground plane with
multiple vias.
