10.2 Technical Info
Technical description
This interface is made for serial digital video (4:2:2) according to SMPTE259 (270Mbit/s).
The input signal is amplified (with equalizer) and sampled with a regenerated clock. A copy of the regenerated input signal is buffered
to a BNC-output. The serial bitstream is transformed into a parallel 10-bit YCbCr stream. Horizontal, vertical sync and field signal
are derived from the 10-bit stream. The YCbCr stream is decoded into RGB signals which connect to the PMP through an Euro
connector. Contrast, saturation and brightness adjustment are possible.
Horizontal and vertical sync are both active high during blanking. The field signal is high during field 1 and low during field 2.

LEDs on board
On this PCB, 2 red LEDs are present.
•
SMD LED (D300) (A) which indicates whether the FPGA is configured or not. When the LED is "on", the FPGA is NOT config-
ured.
•
Discrete LED (D301) (B), visible from the outside via an aperture in the front plate, indicates whether the SDI module is selected
or not. When the LED is "on", the module is selected.
