The Motorola MC44011, a member of the MC44000 Chroma 4 family, is
designed to provide RGB or YUV outputs from a variety of inputs. The inputs
can be composite video (two inputs), S–VHS, RGB, and color difference
(R–Y, B–Y). The composite video can be PAL and/or NTSC as the MC44011
is capable of decoding both systems. Additionally , R–Y and B–Y outputs and
inputs are provided for use with a delay line where needed. Sync separators
are provided at all video inputs.
In addition, the MC44011 provides a sampling clock output for use by a
subsequent triple A/D converter system which digitizes the RGB/YUV
outputs. The sampling clock (6.0 to 40 MHz) is phase–locked to the
horizontal frequency.
Additional outputs include composite sync, vertical sync, field
identification, luma, burst gate, and horizontal frequency.
Control of the MC4401 1, and reading of status flags, is via an I2C bus.
• Accepts NTSC and PAL Composite Video, S–VHS, RGB, and R–Y, B–Y
• Includes Luma and Chroma Filters, Luma Delay Lines, and Sound Traps
• Digitally Controlled via I
• R–Y, B–Y Inputs for Alternate Signal Source
• Line–Locked Sampling Clock for A/D Converters
• Burst Gate, Composite Sync, Vertical Sync and Field Identification Outputs
• RGB/YUV Outputs can Provide 3.0 Vpp for A/D Inputs
• Overlay Capability
• Single Power Supply: 5.0 V, ±5%, 550 mW (Typical)
• 44 Pin PLCC and QFP Packages

the decoded composite video at Pin 1 or 3. It is
internally directed to the color difference stage.

System Select – A multi–level dc output which
indicates the color decoding system to which the
PAL/NTSC detector is set by the software. This output
is used by the MC44140 chroma delay line.
Sandcastle Pulse – A multi–level timing pulse output
used by the MC44140 chroma delay line. This pulse
encompasses the horizontal sync and burst time.
Xtal 2 (36), Xtal 1 (38) – Designed for connection of 4x
subcarrier color crystals. Selection is done in software.
The selected frequency is used by the PAL/NTSC
detector; system identifier; all notches and traps; delay
lines; and the horizontal calibration circuit.
The crystal frequency should be:
14.3 MHz at Pin 36 for NTSC,
17.7 MHz at Pin 38 for PAL.
(See Table 17 for crystal specifications)
Ground 1 – Ground for all sections except PLL #2
and the color difference stage.
V
– A 5.0 V (±5%), supply to all sections except
CC1
PLL #2 and the color difference stage.
B–Y Output – Output from the PAL/NTSC decoder, it
is typically capacitor–coupled to a delay line or to the
B–Y input. This pin is clamped, and filtered at the
color subcarrier frequency , 2x, and 8x that frequency.
3642(Same as Pin 41)R–Y Output – Output from the PAL/NTSC decoder.

Power Distribution – The three VCC pins must be
externally connected to 5.0 V (±5%) supply. The four
grounds must be externally tied together, preferably to
