Technical Specification
A visual indication of the lock status of the reference is provided. If configured to
lock to the studio reference via the HSYNC IN connector, the MX8400 raises an
alarm condition if the HSYNC input fails.
B.4.3 H SYNC OUT
When configured to lock to an external studio reference, the reference signal from
the HSYNC OUT connector is the same line standard as the input HSYNC.
When there is no HSYNC input or the MX8400 is configured to use an internal clock
reference, the output is selectable between 625 HSYNC and 525 HSYNC.
