Differential IF Outputs. These ports are active when the register bit IF_SEL is
1. They do not support FM mode. These pins must be inductively pulled up
to V
IFINH+ or IFINH-. The pullup inductors can be part of the filter structure. The
differential output impedance of this port is nominally 600Ω. The transmission
lines from these pins should be short to minimize the pickup of spurious sig-
nals and noise.
Differential IF Outputs. These ports are active when the register bit IF_SEL is
0. These pins must be inductively pulled up to V
pass filter is connected between this port and IFINL+ and IFINL-. The pullup
inductors can be part of the filter structure. The differential output impedance
of this port is nominally 600Ω. The transmission lines from these pins should
be short to minimize the pickup of spurious signals and noise.
RF and IF Gain Control Analog Input. Apply 0.6V to 2.4V to control the gain of
the RF and IF stages. An RC filter on this pin should be used to reduce DAC
noise or PDM clock spurs from this line.
Supply Pin for the IF VGA. Bypass with a capacitor as close to the pin as
possible. The bypass capacitor must not share its ground vias with any other
branches.
Supply for the I/Q Modulator. Bypass with a capacitor as close to the pin as
possible. The bypass capacitor must not share its ground vias with any other
branches.
Differential Q-Channel Baseband Inputs to the Modulator. These pins go
directly to the bases of a differential pair and require an external common-
mode bias voltage.
Differential I-Channel Baseband Inputs to the Modulator. These pins go
directly to the bases of a differential pair and require an external common-
mode bias voltage.
Shutdown Input, Drive to Logic High for Normal Operation. A logic low on
SHDN shuts down the entire IC except the serial interface and retains the
information in all registers. An R-C lowpass can be used to filter digital noise.
Supply Pin to the VCO Section. Bypass as close to the pin as possible. The
bypass capacitor should not share its vias with any other branches.
Buffered LO Output. Control the output buffer using register bit BUF_EN and
the divide ratio using the register bit BUF_DIV.
Differential Tank Pins for the Low-Frequency IF VCO. These pins are internally
biased. VCO_SEL = 0 selects this IF VCO.
