3.3.2 Internal Clocking and Multi-card Systems

Clock connections to internal equipment are provided via the header CLOCK IN and CLOCK OUT connectors on

the AES16 board. Refer to Figure 1 for the location of these connectors. The connectors support 75-ohm, TTL level

signals. If you are connecting to another Lynx digital audio card, the Lynx Internal Clock Cable (CBL-ICC) or

Universal Clock Cable (CBL-UCC) should be used.

Connect the CLOCK IN connector to the clock output of an internal device and select “Header” as the clock source

in the Lynx mixer. Adjust the clock Reference to match the incoming clock type.

The signal on the CLOCK OUT header is a word clock that tracks the sample rate of the AES16. Connect this

output to the word clock input of an internal device or another AES16.

As shown below in Figure 3, multiple AES16s can be synchronized using the optional Internal Clock Cable. A daisy

chain of CLOCK OUT to CLOCK IN is created so that all cards are tightly synchronized. Refer to Section 9

Configuring Multiple AES16’s for more information.

Figure 3: Synchronizing Multiple AES16's Using Internal Clock Connections

Note: If an appropriate internal clock cable is not available, multiple cards can be synchronized externally by using

the BNC clock connections on the CBL-AES1604 cable. Use a standard 75-ohm BNC coaxial patch cable to

connect the input clock signals to the output clock signals.
