JABBER FUNCTION
When valid data on the TX± pins is detected, the
jabber timer is started. If there is valid data for more
than 20 ms, a latch is set which disables the
transmitter output and enables the 10 MHz output on
the CD± pins. The latch is reset within 0.5 seconds
after the valid data is removed from the transmitter
input (TX±). This action resets the jabber timer and
disables the 10 MHz signal on the CD± pins. The
TX± inputs must remain inactive during the 0.5
second reset period.
HEARTBEAT FUNCTION
The 10 MHz CD outputs are enabled for about 1 s
at approximately 1.1 s after the end of each
transmission. The heartbeat signal tells the DTE that
the circuit is functioning. This is implemented by
starting the heartbeat timer when the valid data
signal indicates the end of a transmission. This
function is disabled when HBE pin is tied to VEE.
