Pin Configurations (continued)
Rx Gain Control
The receiver gain can be set either by the digital input
pins B1 through B7 or by the internal Rx gain register.
The gain-control characteristic is shown in the Typical
Operating Characteristics.
RSSI
The RSSI output can be configured for two output
voltage ranges: 0.5V to 2V and 0.5V to 2.5V (see
Table 16a). The RSSI output is unaffected by the Rx
VGA gain setting. They are capable of driving loads
up to 10kΩ || 5pF.
Tx VGA Gain Control
The Tx gain can be set either by digital input pins B1
through B6 or by the internal Tx VGA gain register. The
linearity of the Tx blocks can also be adjusted (Table 17).
The Tx VGA gain-control characteristic is shown in the
Typical Operating Characteristics.
Loop Filter
The loop-filter topology and component values can be
found in the MAX2828/MAX2829 evaluation kit data
sheet. A 150kHz loop bandwidth is recommended to
ensure that the loop settles fast enough during Tx/Rx
turnaround times.
