3 Description
The DPHY440 is a one to four lane and clock MIPI
DPHY re-timer that regenerates the DPHY signaling.
The device complies with MIPI DPHY 1.1 standard
and can be used in either a MIPI CSI-2 or MIPI DSI
application at datarates of up to 1 Gbps.
The device compensates for PCB, connector, and
cable related frequency loss and switching related
loss to provide the optimum electrical performance
from a CSI2/DSI source to sink. The DPHY440’s
DPHY inputs feature configurable equalizers.
The output pins automatically compensate for uneven
skew between clock and data lanes received on its
inputs ports. The DPHY440 output voltage swing and
edge rate can be adjusted by changing the state of
the VSADJ_CFG0 pin and ERC pin respectively.
The DPHY440 is optimized for mobile applications,
and contains activity detection circuitry on the DPHY
Link interface that can transition into a lower power
mode when in ULPS and LP states.
The SN65DPHY440SS is characterized for an
industrial temperature range from -40ºC to 85ºC while
SN75DPHY440SS is characterized for commercial
temperature range from 0ºC to 70ºC.
