+3.3V Rising Edge Data Strobe LVDS Receiver 28-Bit
Channel Link—66 MHz, +3.3V Rising Edge Strobe LVDS
Receiver 21-Bit Channel Link—66 MHz
General Description
The DS90CR286A receiver converts the four LVDS data
streams (Up to 1.848 Gbps throughput or 231 Megabytes/sec
bandwidth) back into parallel 28 bits of CMOS/TTL data. Also
available is the DS90CR216A that converts the three LVDS
data streams (Up to 1.386 Gbps throughput or 173
Megabytes/sec bandwidth) back into parallel 21 bits of
CMOS/TTL data. Both Receivers' outputs are Rising edge
strobe.
Both devices are offered in TSSOP packages.
The DS90CR286A / DS90CR216A devices are enhanced
over prior generation receivers and provided a wider data
valid time on the receiver output.
This chipset is an ideal means to solve EMI and cable size
problems associated with wide, high speed TTL interfaces.
