TOTAL DEVICE
Operating Voltage
T A = 25 C
T A = 0 C to 70 C
Power Supply Current (V CC = 5.0 V)
V in = 1.0 mVrms signal at 45.75 MHz with 75% modulated staircase at 3.58 MHz.
NOTES: 1.
2. V in = 100 µVrms signal at 41.25 MHz added to signal in Note 1.
3. Differential carrier level at video IF inputs to cause the negative detector output to go positive by 0.1 V from ground.
4. FM Modulation = 25 kHz deviation at 1.0 kHz for 4.5 MHz intercarrier.
5. AM Modulation = 30% depth at 1.0 kHz for 4.5 MHz and 5.5 MHz intercarrier.
6. AM Rejection (dB) = 20 log
7. Tested with 15 µH sound quadrature coil in parallel with 68 pF and 10 kΩ.
8. The AFT output can be disabled by leaving Pin 12 disconnected or by biasing it to the voltage level shown above. When disabled, the output will be
internally clamped to one half of V CC .
