4 The SAM08 Card
Introduction The AXON SAM08 is an SDI to Composite converter / de-embedder
with a built-in SDI distribution amplifier. Its main application is use as a
one to four SDI distribution amp with 2 analog composite and 2 analog
audio outputs.
The analog audio outputs can be configured to de-embed any 2 channels
out of 16 channels of audio that are available in the SDI domain.
The analog audio is routed to the lower BNC outputs of the connector
panel and is default unbalanced. An optional Connector panel BPA09
can be provided that outputs a balanced audio signal at +24dBu max by
means of a high quality Transformer that is placed on the connector
panel.
Key Features The Key features of the SAM08 are as follows
Analog Composite
and YC outputs
Two Composite or one set of YC outputs are provided by the
SAM08. The digital to analog conversion of each output is
performed using 10bit converters in order to ensure high quality..
Audio De-embedder
An Audio de-embedder is provided allowing of any of the
incoming 16 audio channels to be selected to either of the two
analog audio outputs.
Automatic Cable
Equalization
The SAM08 employs automatic cable equalization to compensate
for cable losses up to a maximum length of 350m.
Four Re-Clocked
SDI OUtputs
Four re-clocked SDI outputs are provided to enable the incoming
SDI signal to be distributed to other devices. Re-clocking the
signal ensure that the timing of the SDI signal is accurate.
Standard Selection Automatic or manual selection of 525 TV line and 652 TV line
systems is provided by the SAM08 allowing use in multi-standard
systems.
Blanking Modes The SAM08 has sophisticated vertical blanking, allowing pass-
through or blanking that enables the input blanking to be
maintained or modified.
Internal Test Signal
Generator
The SAM08 card has an internal test signal generator that has a
selectable 75% Color Bars test pattern.
