3 Description
The DPHY440 is a 1-lane to 4-lane and clock MIPI®
DPHY retimer 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 1.5Gbps.
The device compensates for PCB, connector, and
cable related frequency loss and switching related
loss to provide the optimum electrical performance
from a CSI-2/DSI source to sink. The DPHY440
DPHY inputs feature configurable equalizers.
The output pins automatically compensate for uneven
skew between clock and data lanes received on the
inputs ports of the device. 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 –40°C to
85°C while SN75DPHY440SS is characterized for
commercial temperature range from 0°C to 70°C.
