+3.3V LVDS Receiver 24-Bit Flat Panel Display (FPD) Link
—85 MHz, +3.3V LVDS Receiver 18-Bit Flat Panel Display
(FPD) Link—85 MHz
General Description
The DS90CF386 receiver converts the four LVDS data
streams (Up to 2.38 Gbps throughput or 297.5 Megabytes/
sec bandwidth) back into parallel 28 bits of CMOS/TTL data
(24 bits of RGB and 4 bits of Hsync, Vsync, DE and CNTL).
Also available is the DS90CF366 that converts the three
LVDS data streams (Up to 1.78 Gbps throughput or 223
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 (DS90C385/
DS90C365) will interoperate with a Falling edge strobe Re-
ceiver without any translation logic.
The DS90CF386 is also offered in a 64 ball, 0.8mm fine pitch
ball grid array (FBGA) package which provides a 44 % re-
duction in PCB footprint compared to the 56L TSSOP pack-
age.
