Scart2
This is an LA42052 which is the audio amplifier for the set. It has left and right inputs from the LOC and left and right
outputs to the speakers and headphone socket. It also has mute and standby functions which are activated by the
LOC as appropriate.
IC1101 (monitor sets only)
This is a switching IC, NJM2233BM, which allows the sync signal input on monitor sets to be switched between pin
20 of SCART 1 (conventional & ALBOS) and pin 14 of SCART 1 (SIS signal). The IC takes a 5V supply and is
switched by the control line SC2_8, which is normally used for SCART 2 pin 8 signalling but is adapted fro the moni-
tor sets.
IC1205
This a ROHM BA7603F triple video switch which allows the RGB input to be switched between SCART 1 and
SCART 2. The switch is controlled by the RGB_SW line from the IC.
IC2001
This is a picture improvement chip, Philips TDA9178, which takes a YUV input from the LOC and carries out vector
processing of luminance and colour to improve overall picture quality and reduce noise. The IC requires an 8V
power supply and is also connected to the I2C bus.
IC201
This is the Philips LOC 1 chip which is the main system processor. It consists of three ICs encapsulated in one BGA
package with 388 balls. The “Cosmic” and “Picasso” chips carry out analogue and digital processing respectively,
and together from the UOC III which is used in many other sets. These are complemented by the Lithium IC which
carries out digital processing and scaling functions.
The IC requires 5V, 3.3V and 1.8V for correct operation – although only 5V and 3.3V are required in “standby”
mode. Full descriptions of all port functions are given elsewhere in this manual.
IC1221(digital only)
This is a ROHM BA7609F triple video switch which allows audio and video from the digital system to be output to
the SCART 2 socket for recording. The IC is controlled by the REC_CTL signal from the MCU IC860.

This is a linear voltage regulator providing in this case 8V to supply the picture improvement IC IC2001. The regulator is switched by the control line POWER 1.
IC6605
This is a chopper regulator, Sharp PQ1CY series, which provides 6V. This voltage is clamped by a diode after the
regulator to produce 5V CPU. This voltage is passed to IC 6606.
IC6606
This is a linear voltage regulator, ROHM BA05SFP, which takes the 6V from IC6605 as an input and produces 5V
SW. This regulator is controlled by the POWER 1 control line from the LOC.
IC6607
This is a linear voltage regulator which takes the 6V from IC6605 and produces 3V3 STB used by the LOC in standby mode.
IC6608
This is a ROHM BA00BC0WFP linear regulator which converts the 6V from IC6605 to the 1V8 use by the LOC
when the set is powered on. This regulator is controlled by the POWER 1 control line.
IC6642
This is also a ROHM linear regulator which takes the 5V SW from IC6606 as an input and produces 3V3 SW used
by various parts of the circuit.
IC701 (20” LCD only)
This is a THine THC63LVDF84B LCD panel interface which converts 4 LVDS data streams from the LOC into 28bits
of RGB data and a clock to send to the panel. Currently this IC is only required on 20” LCD sets where the panel
requires data in RGB form rather than LVDS.
The IC requires a 3V3 power supply on several pins.
IC801
This is the non-volatile memory(NVM) IC which contains data settings for the LOC and stored user data such as picture settings and programs. It also contains data relating to the LCD panel type and data requirements. It is a 24C64
64K EEPROM arranged as 8192 x 8bits. It uses the 3V3 STB power supply and is connected to the LOC via the
12C bus.
IC860(digital only)
This is a Renesas RSF21162SP microprocessor which acts as a controller for the digital module via the I2C bus and
the D/A_CTL and REC_CTL line to IC1251 and IC1221. This IC has a small amount of memory which contains the
ICs program, this is programmed separately from the LOC program via the KSUB socket.
IC861(digital only)
This is a ROHM BD4828G CMOS voltage detector which controls the reset line to the IC860 microprocessor.
