MOTOROLA ANALOG IC DEVICE DATA
The MC44462 Y–C PIP controller is a low cost member of a family of high
performance PIP controllers and video signal processors for television. It is a
follow–up to the MC44461 PIP and has a modified input selection to allow
higher performance in TV systems which have S–Video inputs on the back
panel. The S–Video input is separate luma (luminance) and chroma
components. It is NTSC compatible and contains all the analog signal
processing, control logic and memory necessary to provide for the overlay of
a small picture from a second non synchronized source onto the main picture
of a television. All control and setup of the MC44462 is via a standard two pin
I2C bus interface. The device is fabricated using BICMOS technology. It is
available in a 56–pin shrink dip (SDIP) package.
The main features of the MC44462 are:
• Switchable PIP Composite Video Signals – Video 1 and Video 2
• S–Video Output Allows High Performance in TV
• Two PIP Sizes; 1/16 and 1/9 Screen Area
• Freeze Field Feature
• Variable PIP Position in 64–X by 64–Y Steps
• PIP Border with Programmable Color
• Programmable PIP Tint and Saturation Control
• Automatic Main to PIP Contrast Balance
• Vertical Filter
• Integrated 64 k Bit DRAM Memory Resulting in Minimal RFI
• Minimal RFI Allows Simple Low Cost Application into TV
• I

C Bus Control – No External Variable Adjustments Needed
• Operates from a Single 5.0 V Supply
• Economical 56–Pin Shrink DIP Package

I2C REGISTER DESCRIPTIONS
Base write address = 24h
Base read address = 25h
Read Register
There are two active bits in the single read byte available
from the MC44462 as follows:
Write Vertical Indicator (WVI0) – D7
When 0 indicates that the write operation specified by the
last I2C command has been completed.
PIP Sync Detect Bit (PSD0) – D1
When 0 indicates that the PIP video H pulses are present
and the horizontal timebase oscillator is within acceptable
limits.
Write Registers
Read Start Position/Write Start Position Registers
Sub–address = 00h
Write Raster Position Start Bits (WPS0–2) – D0–D2
Establishes the horizontal beginning of the PIP and its
black level measurement gate. This beginning may be varied
by approximately 3.0 µs. The position of this pulse may be
observed through the Multi Test Pin 30 (See Test Mode
Register Sub–address 03h).
Read Raster Position Bits (RPS0–3) – D4–D7
Establishes the clamp gate position for the black level
reference for the main picture. This position may be varied by
approximately 5.0 µs. The position of this pulse may be
observed through the Multi Test Pin 30 (See Test Mode
Register Sub–address 03h).
Pip Switch Delay/Vertical Filter Register
Sub–address = 01h
PIP Switch Delay Bits (PSD0–3) – D0–D3
Delays the start of PIP on time relative to the PIP picture.
These bits are used to center the PIP border and PIP picture
in the horizontal direction.
Vertical Filter Bit (VFON) – D4
When the filter is activated (VFON = 1) a three line
weighted average is taken to provide the data stored in the
field memory.
Border Color Register
Sub–address = 02h
Border Color Bits (BC0–2) – D0–D2
These Bits control the color of the border. Note that when
using one of the saturated border colors it is possible to get
objectionable dot crawl at the edge of the border in some TVs
unless appropriate comb filtering is used in the TV circuitry.
White
Test Mode/Main Vertical and Horizontal Polarity Register
Sub–address = 03h
Internal Test Mode Register (ITM0–2) – D0–D2
Sets the Multi Test Pin output to provide one of several
internal signals for test and production alignment. Also
controls the test memory address counter.
Multi–Test I/O and Function
Input – Digital Test mode
Output – Main Clamp
Main vertical polarity select bit (MVP0) – D6
Selects polarity of active level of vertical reference input.
0 = positive going, 1 = negative going.
Main horizontal polarity select bit (MHP0) – D7
Selects polarity of active level of horizontal reference
input. 0 = positive going, 1 = negative going.
PIP Freeze/PIP Size/Main and PIP Video Source Register
Sub–address = 04h
PIP Freeze Bit (STIL0) – D4
When set to one, the most recently received field is
continuously displayed until the freeze bit is cleared.
PIP Size Bit (PSI90) – D5
Switches the PIP size between 1/16 main size (when 0)
and 1/9 main size (when 1).
Video Type Select Bit (YCPSEL) – D6
Selects which video type will be applied to the PIP input.
PIP Video Source Select Bit (PSEL0) – D7
Selects which composite video input will be applied to the
video decoder to provide the PIP video in CV mode.
CV2 Input to PIP
PIP On/PIP Blank Register
Sub–address = 05h
PIP On Bit (PON0) – D0
When on (1) turns the PIP on.
PIP Blanking Bit (PBL0) – D4
When on (1) sets the PIP to black. If the PIP is off, then it
will be black if it is turned on. Overrides all other settings of
the PIP control.
PIP X Position Register
Sub–address = 06h
X Position Bits (XPS0–5) – D0–D5
Moves the PIP start position from the left to the right
edge of the display in 64 steps. There is protection circuitry

MC44462
6
MOTOROLA ANALOG IC DEVICE DATA
to prevent the PIP from interfering with the main picture
sync pulses.
PIP Y Position Register
Sub–address = 07h
Y Position Bits (YPS0–5) – D0–D5
Moves the PIP start position from the top to the bottom
edge of the display in 64 steps. There is protection circuitry to
prevent the PIP from interfering with the main picture sync
pulses.
PIP Chroma Level Register
Sub–address = 08h
Chroma (C0–5) – D0–D5
The color of the PIP can be adjusted to suit viewer
preference by setting the value stored in these bits. A total of
64 steps varies the color from no color to maximum. This
control acts in conjunction with the auto phase control.
PIP Tint Level Register
Sub–address = 09h
Tint (T0–5) – D0–D5
An auto phase control compares the main color burst to
the internally generated pseudo color burst so that the tints
are matched. In addition to this, the tint of the PIP can be
varied ±10° in a total of 64 steps by changing the value of
these bits to suit viewer preference.
PIP Luma Delay Register
Sub–address = 0Ah
Y Delay (YDL0–2) – D0–D2
Since the Chroma passes through a bandpass filter and
the color decoder, it is delayed with respect to the Luma
signal. Therefore, to time match the Luma and Chroma these
bits are set to a single value determined to be correct in the
application.
Pip Fill/Test Register
Sub–address = 0Ch
PIP Fill Bits (PIPFILL0–1) – D0–D1
May be used to fill the PIP with one of three selectable
solid colors
Test Register Bits (INTC0 and MACR0) – D6–D7
Used for production test only.
