J1, J2
RF Input/Output – RF input/output port.
2, 3, 4, 5, 6,
GND
Equipotential Point – Internal circuit common,
7, 8, 9
which must be connected to the PCB ground or
common via the lowest possible impedance.
11
VCC
Positive supply voltage input – Must be bypassed
to commmon via a 0.01 F, or larger, capacitor.
12, 13
C1, C2
Charge Pump Capacitor – Capacitor that
accumulates charge to produce negative voltage
supply. This capacitor is 0.025 F, nominal.
14
VCC
Source Voltage Input – Filter terminal for
negative supply voltage. Must be bypassed to
commmon via a 0.01 F, or larger, capacitor.
15
CTL16
Control Voltage 16 – High impedance control
voltage input. The logic level voltage applied to
this pin determines whether the 16 dB bit (MSB)
is switched into the main signal path or is
bypassed.
16
CTL8
Control Voltage 8 – High impedance control
voltage input. The logic level voltage applied
to this pin determines whether the 8 dB bit is
switched into the main signal path or is
bypassed.
17
CTL4
Control Voltage 4 – High impedance control
voltage input. The logic level voltage applied to
this pin determines whether the 4 dB bit is
switched into the main signal path or is
bypassed.
18
CTL2
Control Voltage 2 – High impedance control
voltage input. The logic level voltage applied to
this pin determines whether the 2 dB bit is
switched into the main signal path or is
bypassed.
19
CTL1
Control Voltage 1 – High impedance control
voltage input. The logic level voltage applied to
this pin determines whether the 1 dB bit (LSB)
is switched into the main signal path or is
bypassed.
20
N/C
No internal connection.
