TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA8710S
SIF CONVERTER FOR TV AND VTR
The TA8710S incorporates a 500kHz oscillator and mixer in a
7-pin SIP package, which converts each of the sound carrier, 5.5,
6.0 and 6.5MHz into 6.0MHz.
Since this can process 5.5 and 6.6MHz SIF signals as 6.0MHz
signals, the sound signal processing stage of multi standard TV
and VTR can be simplified.
The recommended supply voltage range is ±10% for V

Connect a 500kHz Ceramic resonator between this
pin and pin 2.
This is an SIF signal input terminal of 5.5, 6.0 and
6.5MHz signals.
This will be mixed with a 500kHz oscillator output and
converted to 6.0MHz signal.
