Serial/Parallel-Controlled Digital VGA
If desired, the user can also program two additional
attenuation states by using the STA_B_1 control bit as a
second I/O pin. These two additional attenuation settings
are useful for software-defined radio applications where
multiple static gain settings are needed to account for
different frequencies of operation, or where multiple
dynamic attenuation settings are needed to account for
different blocker levels (as defined by multiple wireless
standards).
Power-Supply Sequencing
The sequence to be used is:
1) Power supply
Layout Considerations
The pin configuration of the device is optimized to facili-
tate a very compact physical layout of the device and its
associated discrete components. The exposed pad (EP)
of the device’s 48-pin thin QFN-EP package provides a
low thermal-resistance path to the die. It is important that
the PCB on which the device is mounted be designed
to conduct heat from the EP. In addition, provide the EP
with a low inductance path to electrical ground. The EP
MUST be soldered to a ground plane on the PCB, either
directly or through an array of plated via holes.
