DVI Video Development Board

The Client was working on a laser projection system and
needed a flexible controller board to accept a variety of
video formats. Internal staff and consultants had done most
of the work, but were running short of time to get the job
built. The company brought a mostly complete set of
schematics to Bolton Engineering, and Bolton Engineering
finished off the design, created the circuit board layout,
and built prototype boards. |

System
Overview
The Development Board contained a variety of interfaces.
Some interfaces were very high speed and required
matched length and matched impedance tracks. Some tracks
had severe requirements for signal crosstalk.
- Serial RapidIO packet-switched interface, running at
2.5GBPS.
- DVI input, to Analog Devices AD9887A 140MSPS DVI Input
with sync processor and clock PLL.
- RGB Video Output to 50 Ohm, 8-bits at 180MSPS.
- High-speed 12-bit A/D channel, 210MSPS for composite
and HD video
- Programmable 14-bit D/A, 180MSPS, used by client as
flexible waveform generator
- Large custom-programmed FPGA in 1020 pin BGA.
- Two serial RS-232 ports.
- Thirty-two lines digital I/O
- Expandable connector slot into which boards with new
functionality may be placed
- Multi-Voltage Power Supply, for on-board logic and for
other system electronics
Project Scope
Bolton Engineering completed the schematics, performed a
design review on critical design sections, and designed
the circuit board. Bolton Engineering also bought
components, fabricated and assembled boards, and did a
first level hardware debug and system bringup. The
project was completed in twelve weeks, on schedule for a
company demonstration. The first-pass boards performed
all required functions and worked to specification. |
