RGB PROCESSOR IC
The TA8884AN is an RGB processor IC for digital-analog
system color TV. TA8884AN organizes digital-analog TV
system by combined with TC90A02F or TC90A06F (Digital
VCD IC: TOSHIBA Product). Input signals are Luminance
signal and color difference signals which have been
demodulated by digital IC. And RGB primary color signals
are outputted.
TA8884AN contains IZC bus, so various control and setting
of various function can be digital-controled through the
bus line.

(TEST CONDITION : VCC-- 12V, Ta =25°C)
OSD High Level Mode
ON Voltage
mmmmmm
(1)Apply external supply 5V to pin 17.
(2) Connect external supply to pin 23 and raise voltage
from 0V slowly.
(3) Measure pin 18 voltage when pin 13 picture period
voltage changes. [VOSD RH'ON]
(4) Repeat (2) and (3) when applying voltage to pin 19 to
measure pin 14 [VOSD GHI ON] and pin 20 to pin 15
[VOSD " ON], likewise.
OSD Mode Change
Characteristic
Same as
(1) Input signal 4 (signal amplitude : 3Vp-p) to pin17.
(2) Measure change characteristic for pin 13, 14 and 15, in
accordance with the diagram 2.
[TROSD R, tPROSD R, TFOSD R, tPFOSD R:
TROSD G, tPROSD G, rFoso G, tPFOSD G,
TROSD B, tPROSD B, rFoso B, tPFOSD B]
(3) From the above measurement data, calculate max.
difference between axes of transmission delay time at
rise and fall time. [AtPR05D, AtPFOSD]
OSD High Mode
Change Characteristic
Same as
(1)Apply external supply 5V to pin17.
(2) Input signal 4 (signal amplitude : 3Vp-p) to pin 18.
(3) Measure change characteristic for pin13, 14 and 15, in
accordance with the diagram 2.
[TROSD il tPROSD RHI, rFoso il tPFOSD RH']
(4) Repeat (2) and (3) when pin 19 (input) pin 14
(measure),
[TROSD tsm, tPRoso tl, TFOSD GH', tPFoso GH'L
and pin 20 pin 14, likewise.
[TROSD BH': tPROSD BH': rFoso il tPFOSD BH']
(5) From the above measurement data, calculate max.
