PI2EQXDP101-A
1 to 1 DisplayPort⢠ReDriverâ¢
Features
⢠DisplayPort⢠1.1a operation at reduced bit rate (1.62Gbps)
and high bit rate (2.7Gbps)
⢠Jitter elimination circuits automatically adjust link via training
path
à à Pre-Emphasis, and output swing
⢠Can support all 4 levels of output swing and 4 levels output
pre-emphasis, as specified in the DisplayPort 1.1a spec.
⢠AUX interception circuit only listens to the link training, but
does not affect link training
⢠Low insertion loss across the AUX signal path (0.35dB
@1Mbps)
⢠Output can support dual mode DP by providing DDC signals
across the AUX_sink pins
à à Using Cable Detect pin from DP connector (pin 13),
the switch can toggle between DP and TMDS mode.
⢠Automatic power down state when HPD signal is LOW
⢠Enters low power mode when no data signal is present
⢠Dual power supply (1.5V and 3.3V)
⢠2KV HBM ESD protection
⢠50 ohm output termination can be turned off when port is off
à à Port is turned off automatically when not needed
⢠Package (Pb-Free & Green available)
à à 36-pin TQFN (ZF)
Description
The PI2EQXDP101-A is a one Input and one Output DisplayPortâ¢
ReDriver⢠that support a maximum data rate of 2.7 Gbps through
each channel, which results in a total of 10.8Gbps through-put.
Output Level Swing and Output Pre-emphasis and number of
active lanes are controlled by decoding the AUX command
during link initialization. Also, utilizing the HPD signals from
each DisplayPort port, the PI2EQXDP101-A can automatically
enter power down state.Or, if the graphics driver is off and has
no output signal, Pericomâs PI2EQXDP101-A can automatically
enter low power mode, even if an active monitor is attached.
