DS90C383/DS90CF384 +3.3V Programmable LVDS 24-Bit-Color Flat Panel Display (FPD)
Link—65 MHz
General Description
The DS90C383 transmitter converts 28 bits of LVCMOS/ LVTTLdata into four LVDS (Low Voltage Differential Signal­ing) data streams. A phase-locked transmit clock is transmit­ted in parallel with the data streams over a fifth LVDS link. Every cycle of the transmit clock 28 bits of input data are sampled and transmitted. The DS90CF384 receiver con­verts the LVDS data streams back into 28 bits of LVCMOS/ LVTTLdata.At a transmit clock frequency of 65 MHz, 24 bits of RGB data and 3 bits of LCD timing and control data (FPLINE, FPFRAME, DRDY) are transmitted at a rate of 455 Mbps per LVDS data channel. Using a 65 MHz clock, the data throughputs is 227 Mbytes/sec. The transmitter is of­fered with programmable edge data strobes for convenient interface with a variety of graphics controllers. The transmit­ter can be programmed for Rising edge strobe or Falling edge strobe through a dedicated pin. A Rising edge trans­mitter will inter-operate with a Falling edge receiver (DS90CF384) without any translation logic. Both devices are 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 TSSOP package.
This chipset is an ideal means to solve EMI and cable size problems associated with wide, high speed TTL interfaces.

Note 5: Receiver Skew Margin is defined as the valid data sampling region at the receiver inputs. This margin takes into account the transmitter pulse positions (min and max) and the receiver input setup and hold time (internal data sampling window-RSPOS). This margin allows for LVDS interconnect skew, inter-symbol interference (both dependent on type/length of cable), and clock jitter (less than 250 ps).

Applications Information
The DS90C383 and DS90CF384 are backward compatible with the existing 5V FPD Link transmitter/receiver pair (DS90CR583, DS90CR584, DS90CF583 and DS90CF584). To upgrade from a 5V to a 3.3V system the following must be addressed:
, LVDS VCCand PLL VCCof both the transmitter
CC
and receiver devices. This change may enable the re­moval of a 5V supply from the system, and power may be supplied from an existing 3V power source.
2. The DS90C383 (transmitter) incorporates a rise/fall strobe select pin. This select function is on pin 17, formerly a V rise/fall strobe select pin is connected to V configured with a rising edge strobe. In a system cur­rently using a 5V rising edge strobe transmitter (DS90CR583), no layout changes are required to ac­commodate the new rise/fall select pin on the 3.3V transmitter. The V the device will be configured with a rising edge strobe.
When converting from a 5V falling edge transmitter (DS90CF583) to the 3V transmitter a minimal board layout change is necessary. The 3.3V transmitter will
not be configured with a falling edge strobe if V mains connected to the select pin. To guarantee the
3.3V transmitter functions with a falling edge strobe pin 17 should be connected to ground OR left unconnected. When not connected (left open) and internal pull-down resistor ties pin 17 to ground, thus configuring the trans­mitter with a falling edge strobe.
