FUNCTION
Power Supply. Bypass to GND with capacitors as close to the pin as possible as shown in the typical
application circuits (Figures 1 and 2).
Signal Input. Internally matched to 50 Ω over the operating frequency. See the typical application
circuit for recommended component values.
Ground. Use low-inductance layout techniques on the PC board. Solder the exposed paddle to the
board ground plane.
Attenuation Control Bits. Digital input for attenuation control. See Table 3 for attenuation setting.
Inverted Differential Signal Output. Requires an external pullup choke inductor (120mA typical
current) to V CC along with a DC-blocking capacitor; see Figures 1 and 2.
Noninverted Differential Signal Output. Requires an external pullup choke inductor (120mA typical
current) to V CC along with a DC-blocking capacitor; see Figures 1 and 2.
Amplifier Bias Input. See Figures 1 and 2 for detailed connection.
Bypass Capacitor. See Figures 1 and 2 for detailed connection.
Amplifier DC Ground. Requires choke inductor that can handle supply current. DC resistance of
inductor should be less than 0.2 Ω .
Amplifier Input. Requires DC-coupling to allow biasing.
Compensation Capacitor. Requires connection to AMP IN (pin 15) for stability.
Connect R1 from I SET to GND (see Table 1 or Table 2 for values).
Attenuator Output. Requires external DC-blocking capacitor.
