Description
These are unused pins and not wired inside the package. May be grounded or connected to adjacent pins.
Pins are internally grounded
RF input pin. Connects to 100pF cap inside package.
Jumper this pin on the PC board to the attenuator input (ATIN) pin #6. Connects to 100pF cap inside package.
Attenuator input pin
Parallel interface attenuation control bit 8 dB. When in serial mode P0.5, P1, P2, P4, P8 and P16 logic dictate power up state.
Parallel interface attenuation control bit 4 dB. When in serial mode P0.5, P1, P2, P4, P8 and P16 logic dictate power up state.
Parallel interface attenuation control bit 2 dB. When in serial mode P0.5, P1, P2, P4, P8 and P16 logic dictate power up state.
Parallel interface attenuation control bit 1 dB. When in serial mode P0.5, P1, P2, P4, P8 and P16 logic dictate power up state.
Parallel interface attenuation control bit 0.5dB. When in serial mode P0.5, P1, P2, P4, P8 and P16 logic dictate power up state.
Parallel interface attenuation control bit 16dB. When in serial mode P0.5, P1, P2, P4, P8 and P16 logic dictate power up state.
Attenuator output pin.
Jumper this pin to the attenuator output pin (ATOUT). Connects to 100pF cap inside package.
Connect this pin to the amplifier input pin (AMPIN) with the appropriate AMPIN impedance matching
Amplifier input pin. Internally connected to base of amplifier (~1.3V)
Amplifier RF output pin. Internally connected to 5V. Not matched to 50 ohm. Use appropriate matching circuit.
Power Supply pin to Amplifier. Apply 5.0V to this pin.
Serial interface data input.
Serial interface clock input.
Latch enable input. Parallel mode can also be latch enabled with this pin.
Parallel mode power-up state logic bits. 0/0 = 0dB, 1/0 = 8dB, 0/1=16dB, 1/1=31dB
Jumper this pin to GND on the PC board. Connects to 1000pF cap inside package.
Jumper this pin on PC board to VDD pin 38. Connects to 1000pF bypass cap inside package.
Power supply pin to Digital Attenuator. Apply 2.7-3.3V to this pin. May be set from another voltage with a voltage divider (pulls 40uA typ, 100uA max)
Serial or parallel mode select. Logic low for parallel mode. Logic high for serial mode.
Negative supply voltage or GND
Exposed area on the bottom side of the package . GND with vias as shown in recommended landing pattern.
