TA8865BN
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA8865BN
PLL MULTI PIF / SIF SYSTEM FOR COLOR TV AND VCR
The TA8865BN is a PIF / SIF with PLL detection that is
compatible with the PAL, NTSC and L-SECAM systems.
Intercarrier PLL detection system is adopted to realize high
quality audio in L-SECAM. Use of a 2-stage variable high-gain
SIF AGC amplifier makes possible NICAM compatibility.
The TA8865BN combine these functions in a 36pin dual-in-line
shrink type plastic package.

FUNCTION
14 1st AGC Filter
16 2nd AGC Filter
First and second AGC filters of PIF circuit. This
IC uses keyed AGC in L mode and peak AGC in
BG mode.
15 PIF VCC
VCC for the PIF circuit. External signals could be
mixed in to the IC, causing various
characteristics to be deteriorated. To prevent it,
insert the following trap filters between the
external power supply and this pin. :
PIF carrier frequency trap filter
Horizontal scanning frequency (fH) trap filter.
(In the application circuit, a 68µH coil is
inserted. VCC = 9.0V (Typ).)
17 Mute Filter
The filter of the mute detector. Performs sync
detection between the input sync and fH
generated in the IC.

INTERFACE CIRCUIT
—
18 H.AFC Filter
AFC filter of the horizontal-oscillation PLL circuit.
32fH Vco is controlled by this terminal voltage.
