PIN FUNCTIONS
GND (Pins 1, 2, 7, 8, 10, 13, 15, 16, 19, 22, 25, 26, 28,
31): Ground Pins.
DEC (Pins 3, 6): Decoupling Pin for the Internal DC Bias
Voltage for the Differential Inputs, IN+ and IN–. It is also
connected to the ‘virtual ground’ of the input resistive
attenuator. Capacitive de-coupling to ground is recom-
mended in order to preserve linearity performance when
IN+, IN– inputs are driven with up to 3dB imbalance.
IN+ (Pin 4):
Positive Signal Input Pin with Internal DC
Bias to 2V.
IN– (Pin 5):
Negative Signal Input Pin with Internal DC
Bias to 2V.
PG5 (Pin 9): 4dB Step Amplier Programmable Gain Con-
trol Input Pin. Input levels are controlled by MODE pin.
PG6 (Pin 11): 8dB Step Amplier Programmable Gain
Control Input Pin. Input levels are controlled by the
MODE pin.
PG0 (Pin 12): 0.125dB Step Amplier Programmable
Gain Control Input Pin. Input levels are controlled by
MODE pin.
STROBE (Pin 14): Strobe Pin for the Programmable Gain
Control Inputs (PGx). With STROBE in Low-state, the
Amplier Gain is not changed by PGx state changes (latch
mode). With STROBE in High-state, the Amplier Gain is
asynchronously set by PGx inputs transitions (transpar-
ent-mode). A positive STROBE transition updates the
PGx state. Low-state and High-state depends on MODE
pin level (Table1).
VCC (Pins 17, 24): Power Supply Pins. These pins are
internally connected together.
MODE (Pin 18): PGx and STROBE Functionality and Level
Control Pin. When MODE is higher than VCC – 0.4V, the
PGx and STROBE are DC-coupled. When the MODE pin
is lower than 0.6V, the PGx and STROBE are AC-coupled.
