DESCRIPTION
The SN75DP119 is a 1-lane or 2-lane embedded
DisplayPort (eDP) repeater that regenerates the DP
high speed digital link. The device compensates for
pcb related frequency loss and signal reflections. This
is especially helpful in designs with long pcb traces or
when there is a FET switch in the signal path.
Four levels of differential output voltage swing (V_OD)
and any combination of pre-emphasis using these
V_OD levels are supported. The output swing and
pre-emphasis are configured through device control
inputs. The available output swing levels are
300mV_PP, 400mV_PP, 600mV_PP or 750mV_PP.
Therefore, the output pre-emphasis level can be
configured to 0dB, 2.0dB, 2,5dB, 3.5dB, 5.5dB, 6dB,
or 8dB. This is a good solution for embedded link
applications, such as the connection from the GPU to
the notebook internal panel. To adjust the output
signal level adaptively during link training, the
implementation needs to control the device control
inputs.
The SN75DP119 supports programmable integrated
receiver equalization circuitry. This equalization
circuitry can be used to help improve signal integrity
in applications where the input link has a high level of
insertion loss. The equalizer can be set to 3dB or 6dB
equalization. The equalizer can also be turned off.
The SN75DP119 consumes between 64mW and
175mW depending on the selected mode of
operation. The device also supports an ultra low
power standby mode. In this mode, the outputs are
disabled and the device draws less then 700µW of
power.
The device is characterized for an extended
operational temperature range from 0°C to 85°C.
