3 Description
The DS90CR286AT-Q1 receiver converts four LVDS
(Low Voltage Differential Signaling) data streams
back into parallel 28 bits of LVCMOS data. The
receiver data outputs strobe on the output clock's
rising edge.
The receiver LVDS clock operates at rates from 20 to
66 MHz. The DS90CR286AT-Q1 phase-locks to the
input LVDS clock, samples the serial bit streams at
the LVDS data lines, and converts them into 28-bit
parallel output data. At an incoming clock rate of 66
MHz, each LVDS input line is running at a bit rate of
462 Mbps, resulting in a maximum throughput of
1.848 Gbps.
The DS90CR286AT-Q1 device is enhanced over
prior generation receivers due to a wider data valid
time on the receiver output. The DS90CR286AT-Q1
is designed for PCB board chip-to-chip OpenLDI-to-
RGB bridge conversion. LVDS data transmission over
cable interconnect is not recommended for this
device.
Users designing a sub-system with a compatible
OpenLDI transmitter and DS90CR286AT-Q1 receiver
must ensure an acceptable skew margin budget
(RSKM). Details regarding RSKM can be found in the
Application Information section.
