mostSetSyncSpdifLock

Valid for: CANoe DE

Note
This function is only available with MOST hardware VN2610.

Function Syntax

long mostSetSyncSpdifLock(long channel, long mode);

Description

The function locks the internal S/PDIF timing generator on the S/PDIF input data stream.

Unlock the timing generator if frame synchronization is not possible due to a closed loop configuration. A closed loop means that the S/PDIF input signal is locked through an external S/PDIF device on the S/PDIF output of the network interface.

Parameters

• channel: Channel of the connected interface
• mode:
  • 0: Separates the timing generator from the S/PDIF input data stream.
  • 1: Locks the timing generator on the S/PDIF input data stream.

Return Values

See error codes

Example

Use Cases:

• External S/PDIF source device connected to the S/PDIF In connector of the VN2610

  In this case the VN2610 is S/PDIF Slave (set by mostSetSyncSpdifMode()). In case the VN2610 is configured as TimingSlave it automatically locks the internal S/PDIF timing generator on the S/PDIF input data stream. As TimingMaster there are two possibilities for configuring the VN2610: Please refer to the example given for mostSetClockSource().

• External S/PDIF source and sink device connected to the S/PDIF In and Out connector of the VN2610

  This is not the typical use case but in case of synchronization problems (mentioned above) the timing generator has to be separated from the S/PDIF input data stream.
