• Manufacturer Part Number: TA2012F
• Description: 3V AM / FM IF + MPX (For Digital Tuning System)
• Manufacturer: TOSHIBA [Toshiba Semiconductor]

5. AM local oscillator buffer output
6. Tuning LED driver and stereo LED driver
7.FM detection circuit
For the FM detection circuit,detection coil is able to use instead of ceramic discriminator.
Recommended circuit and recommended coil are as follows.
In this case, please take care that V
· The output impedance of AM local oscillator buffer output pin (pin(4)) is 750Ω (typ.) (cf.P.3)
· It is possible to reduce the output level to add the resistance between the pin(4) and V
· The higher local oscillation frequency (f
·
· Set up the values of R

Frequency
waveform is the rectangular wave, and the level is 500mV
So, in the case that it is connected to other circuits, take care of the input capacity of these circuits and stray
capacity of wire.
The tuning LED driver and stereo LED driver don't have current limit resistance
shown in the right figure. So, it is necessary to add the current limit resistance:
