NAME
DESCRIPTION
1
V
CC
Programmable-Gain Amplifier (PGA) 3.3V Supply. Bypass to GND with a 0.1μF decoupling
capacitor as close to the part as possible.
2
IN+
Positive PGA Input. Along with IN-, this port forms a high-impedance differential input to the PGA.
Driving this port differentially increases the rejection of second-order distortion at low output levels.
3
GND
PGA RF Ground. As with all ground connections, maintain the shortest possible (low-inductance)
length to the ground plane.

Serial-Interface Data. TTL-compatible input. See
Serial Interface
section.
Serial-Interface Clock. TTL-compatible input. See
Serial Interface
section.
Serial-Interface Enable. TTL-compatible input. See
Serial Interface
section.
Transmit Enable. Drive TXEN high to place the device in transmit-enable mode.
Shutdown. When
SHDN
is set low, all functions (including the serial interface) are disabled.
