SDI Inputs
The M2 processor has two SDIinputs.
The SDI A and SDI B inputs are identical in functionality. Each input provides SD-SDI, HD-SDI
and 3G-SDI (both level A and level B). Alternatively, both inputs may be used together for
dual-link HDSDI. All common broadcast resolutions are supported, including 720p50/60,
1080i50/60 and 1080p50/60 and fractional frame rates such as 59.94. For a full list
"Appendix 2: Supported Resolutions" on page124.
The physical connections to the SDI A and B inputs are via standard BNC connectors and in
addition to each input there is a re-clocked thru connector which allows the daisy chaining of
a signal to a second processor or monitor.
There is also an active SDI Out for each channel which is for future implementation.
DVI Input
The M2 processor is fitted with a DVI-Iinput, but the T1 and S4 processors have a DVI-D input.
All Tessera procesors are capable of receiving digital (DVI-D) signals up to full HD 1080p60
resolution at frame rates from 24Hz to 60Hz to a maximum pixel clock of 148.5MHz.
The M2 processor is also capable of receiving analogue VGA/RGBHV inputs up to full HD
(though for this you will need a suitable adaptor for the DVI-I input port).
The DVI-I input may also be used to receive standard definition or high definition component
video (YPbPr) via a passive DVI to BNC breakout cable. In addition to the DVI-I input there is
also a re-clocked DVI-I output.
HDMI can be supported by use of a suitable adapter, however, the Tessera processors does
not support HDCP.
Source selection
The three video inputs on the Tessera M2 processor are mapped to two input pipelines to
allow crossfading between sources.
