2.3.1 DP590 rear-panel component descriptions
This section provides details on the rear-panel components supported by the DP590.
MADI in
Receives PCM signals. This input is an unbalanced 75Ωfemale BNC connector per
AES10-2008.
MADI out
Outputs PCM signals.
SDI in
Only as clock source.
Video in
Only as clock source (based on a voltage reference [VREF] signal).
Command port (Gigabit Ethernet)
Connects a network to administer the unit through a PC web-based user interface.
2.4 Clock source priority
Clock sources are prioritized in a preprogrammed order.
The clock reference source for DP590 is selected automatically, based on a preprogrammed
priority scheme and the availability of the particular sources. The priority is:
1. SDI
2. VREF
3. MADI
The highest available input becomes the clock source. For example, if the SDI clock source is
not available, then the DP590 attempts to sync with VREF, and so on.
In case the reference source becomes asynchronous with the input source, then the DP590
reverts to lock on to the input.
Characteristics of VREF signal as clock source
The VREF (video reference) signal is used only as a clock source in the DP590. VREF connects
through the video-in port. In this case, the supported sync types are CVBS, Y (luma) from Y/C
and YPbPr, and G (sync on green) from GBR with either bilevel or trilevel sync, as specified in
these video standards:
•Composite video (CVBS) and S-Video (Y/C):
•SDTV: SMPTE 170M (NTSC), ITU-R BT.470 (PAL)
•Component video (YPbPr/GBR):
•SDTV: SMPTE 125M, SMPTE 267M, ITU-R BT.601 (480i, 576i)
•EDTV: ITU-R BT.1358 (480P, 576p)
•HDTV: SMPTE 296M (720p), SMPTE 274M (1080i/p), SMPTE RP 211 (1080PsF)
RGB formats that conform to VESA standards used for PC graphics are not supported.
