Clock output interface specifications

The clock output interface is a BNC connector that allows you to provide a clock for
interface timing from the MSAM.

Square or sine waves
1.5 Vpp
5 Vpp with DC offset of 0 V
50 Ohm AC termination impedance
5 Hz to 25 MHz
16 times the baud rate. For example, an external
clock generator set to 153,600 Hz results in a 9600
baud signal out of the MSAM.

16 times the baud rate. For example, an internally
generated line rate of 9600 baud causes a BNC
clock out signal of 153,600 Hz.
