PE43614 UltraCMOS® RF Digital Step Attenuator Recommended Operating Conditions Table 2
lists the recommending operating condition for the PE43614. Devices should not be operated outside the recommended operating conditions listed below.
Table 2 • Recommended Operating Condition for the PE43614 Parameter Min Typ Max Unit Normal mode, VSS_EXT = 0V(1)
Positive supply voltage, VDD 2.3 3.3 5.5 V Positive supply current, I
(3)
DD 170 260 µA
Bypass mode, VSS_EXT = –3.0V(2)
Positive supply voltage, VDD (VDD ≥ 3.4V. See
Table 3
for ful spec 3.1 3.4 5.5 V compliance.) Positive supply current, I
(3)
DD 125 170 µA Negative supply voltage, VSS_EXT –3.3 –3.0 –2.7 V Negative supply current, ISS -40 -16 µA
Normal or bypass mode
Digital input high 1.17 3.60 V Digital input low –0.3 0.6 V Digital input current

10 20 µA RF input power, CW
(5) (7)
28 dBm RF input power, pulsed
(6) (7)
31 dBm Operating temperature range –40 +25 +105 °C
Notes:
1) Normal mode: Connect VSS_EXT (pin 2) to GND (VSS_EXT = 0V) to enable internal negative voltage generator. 2) Bypass mode: Use VSS_EXT (pin 2) to bypass and disable internal negative voltage generator. 3) Due to startup inrush current, a minimum current limit of 600 µA is al owed for normal operation of the DSA. 4) Applies to al pins except pins 18, 22, 23 and 24. P/S (pin 18), A0/D4 (pin 22), A1/D5 (pin 23), and A2/D6 (pin 24) have internal 1.5 MΩ pul -up resistor to internal 1.8V VDD. 5) 100% duty cycle, al bands, 50Ω. 6) ≤ 5% duty cycle, 50Ω. 7) The maximum peak envelope of any OFDM complex waveform signal, such as CP-OFDM, should not exceed the maximum peak RF input power in
