INTERFACE
47
LOOP FILTER
A terminal to be connected with loop filter for
PIF PLL.
The terminal voltage controls the PIF VCO
frequency.
48
EHT IN
The input terminal for EHT.
The ratio of EW/V is controlled by bus.
49
De-Emphasis
A terminal to De-Emphasis Audio signal, and
/Mon-OUT
pick up detected Audio signal. Connect
capacitor (0.01 F to GND).
The time constant 50/75us is set by the
IICBUS control “SIF Freq”.
Remove the capacitor in case of us US/JPN
sound multiplex system.
50
PIF TANK
Terminals to connect a PIF tank coil.
51
The tank coil should be pre-set /- 2%
for the automatic tuning. Manual tuning is
also available.
The resonance capacitance of the tank should
be 18pF.
