DS90CF384A/DS90CF364A
+3.3V LVDS Receiver 24-Bit Flat Panel Display (FPD)
Link—65 MHz, +3.3V LVDS Receiver 18-Bit Flat Panel
Display (FPD) Link—65 MHz
This chipset is an ideal means to solve EMI and cable size
problems associated with wide, high speed TTL interfaces.
General Description
The DS90CF384A receiver converts the four LVDS data
streams (Up to 1.8 Gbps throughput or 227 Megabytes/sec
bandwidth) back into parallel 28 bits of CMOS/TTL data (24
Features
n 20 to 65 MHz shift clock support
bits of RGB and 4 bits of Hsync, Vsync, DE and CNTL). Also
available is the DS90CF364A that converts the three LVDS
data streams (Up to 1.3 Gbps throughput or 170 Megabytes/
sec bandwidth) back into parallel 21 bits of CMOS/TTL data
(18 bits of RGB and 3 bits of Hsync, Vsync and DE). Both
Receivers’ outputs are Falling edge strobe. A Rising edge or
Falling edge strobe transmitter (DS90C383A/DS90C363A)
will interoperate with a Falling edge strobe Receiver without
any translation logic.

The DS90CF384A / DS90CF364A devices are enhanced
over prior generation receivers and provided a wider data
valid time on the receiver output.
n Compatible with TIA/EIA-644 LVDS standard
n Low profile 56-lead or 48-lead TSSOP package
n DS90CF384A is also available in a 64 ball, 0.8mm fine
pitch ball grid array (FBGA) package
The DS90CF384A is also offered in a 64 ball, 0.8mm fine
pitch ball grid array (FBGA) package which provides a 44 %
reduction in PCB footprint compared to the 56L TSSOP
package.
