Loopbacks
For diagnostics, the LXT385 ransceiver has the following loopback modes:
To select a loopback mode when the mode is in:
Analog Loopback
AsFigure 8
connected internally to the receiver inputs RTIP and RRING. For the corresponding receiver, clock
and data signals are output at RCLK, RPOS, and RNEG. (For the LOOP pin settings that select
analog loopback, see
When the LXT385 ransceiver is in an analog loopback, it ignores signals on RTIP and RRING.
* If decoder is enabled, either HDB3 or AMI can be selected.
** Either a transmitter or a receiver can be enabled for use with the jitter attenuator, but not both.
