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.
