SL3522CMC MITEL [Mitel Networks Corporation], SL3522CMC Datasheet - Page 3

• Manufacturer Part Number: SL3522CMC
• Description: 500MHz 75dB Logarithmic/Limiting Amplifier
• Manufacturer: MITEL [Mitel Networks Corporation]

ELECTRICAL CHARACTERISTICS (cont.)
However, characterisation has shown that the device can still function adequately down to frequencies of 50MHz, with the following
reservations:-
with input signal frequencies below 100MHz.
Fig. 24). These can introduce undesirable limiting phase performance for input signal frequencies below 100MHz.

Notes
1 RF output buffer OFF (pin 8 disconnected from 0V)
2 RF output buffer ON (pin 8 connected to 0V)
3 Minimum dynamic range under any single set of operating conditions
4 Log linearity guaranteed for pin = -64dBm to +6dBm for ALL supply, temperature and frequency conditions
5 Full range of supply, temperature and frequency conditions
6 Input limiting range typically -50dBm to +10dBm
7 Not tested, but guaranteed by characterisation
8 Not tested, but guaranteed by design
The SL3522 CANNOT be GUARANTEED to operate below 100MHz and meet the electrical characteristics shown above.
1)The video bandwidth is fixed to approx 40MHz a certain amount of carrier breakthrough on the video O/P (pin 13) will occur,
2)There are 2 RF coupling capacitors (20pF) on-chip, which couple the output signal from stage 3 to the input of stage 4 (ref
