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.
However, characterisation has shown that the device can still function adequately down to frequencies of 50MHz, with the following
reservations:-
1)The video bandwidth is fixed to approx 40MHz a certain amount of carrier breakthrough on the video O/P (pin 13) will occur,
with input signal frequencies below 100MHz.
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
Fig. 24). These can introduce undesirable limiting phase performance for input signal frequencies below 100MHz.
