DS90CF384AQ DS90CF384AQ +3.3V LVDS Receiver 24-Bit Flat Panel Display (FPD) Link - 65 MHz Literature Number: SNLS345 DS90CF384AQ +3.3V LVDS Receiver 24-Bit Flat Panel Display (FPD) Link - 65 MHz General Description Features The DS90CF384AQ receiver converts the four LVDS data streams at up to 1.8 Gbps throughput (227 Megabytes/sec bandwidth) back into parallel 28 bits of LVCMOS/LVTTL data. In a Display application, the 28 bits include: 24 bits of RGB data and up to 4 bits of video control (Hsync, Vsync, DE and CNTL). The DS90CF384AQ device is enhanced over prior generation FPD-Link receivers, provides a wider data valid time on the receiver output and is offered as an AEC-Q100 grade 3 device. FPD-Link is an ideal means to solve EMI and cable size problems associated with wide, high speed LVCMOS/LVTTL interfaces. ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Automotive grade device, AEC-Q100 grade 3 qualified Operating Temperature Range: –40°C to +85°C 20 to 65 MHz shift clock support 50% duty cycle on receiver output clock Best–in–Class Set & Hold Times on RxOUTPUTs Rx power consumption <142 mW (typ) @65MHz Grayscale Rx Power-down mode <200μW (max) ESD rating >7 kV (HBM), >700V (EIAJ) Supports VGA, SVGA, XGA and Dual Pixel SXGA.

This margin takes into account the DS90C383B transmitter pulse positions (min and max) and the receiver input setup and hold time (internal data sampling window - RSPos). The RSKM will change when different transmitters are used. This margin allows for LVDS interconnect skew, inter-symbol interference (both dependent on type/length of cable), and clock jitter (less than 250 ps). 3 www.national.com DS90CF384AQ Receiver Switching Characteristics DS90CF384AQ AC Timing Diagrams 30161102 FIGURE 1. “Worst Case” Test Pattern (Note 5) 30161112 FIGURE 2. “16 Grayscale” Test Pattern (Note 6, Note 7, Note 8) Note 5: The worst case test pattern produces a maximum toggling of digital circuits, LVDS I/O and CMOS/TTL I/O. Note 6: The 16 grayscale test pattern tests device power consumption for a “typical” LCD display pattern. The test pattern approximates signal switching needed to produce groups of 16 vertical stripes across the display. Note 7: Figure 1 and Figure 2 shows a falling edge data strobe (TxCLK IN / RxCLK OUT). Note 8: Recommended pin to signal mapping.
