LVDS Interface ICs 35bit LVDS Receiver 5:35 DeSerializer BU90R104 No.11057EAT09 ●Description LVDS Interface IC of ROHM "Serializer" "Deserializer" operates from 8MHz to 150MHz wide clock range, and number of bits range is from 35 to 70. Data is transmitted seven times (7X) stream and reduce cable number by 3(1/3) or less. The ROHM's LVDS has low swing mode to be able to expect further low EMI. ●Features 1) Five channels of LVDS data stream are converted to 35bits data of parallel LVCMOS level outputs. 2) 30bits of RGB output data, 5bits of timing and control output data(HSYNC, VSYNC, DE, CTL1 and CTL2) are transmitted available. 3) Support clock frequency from 8MHz up to 112MHz. 4) Support consumer video format including 480i, 480P, 720P and 1080i as well. 5) Support many kinds of PC video formats such as VGA, SVGA, XGA and SXGA. 6) Provide 784Mbps per 1ch or 3.92Gbps per device throughput rate using 112MHz clock rate. 7) User programmable LVCMOS data output triggering timing by using either rising or falling edge of clock. 8) 30bit LVDS transmitter is recommended to use BU8254KVT. ●Applications Flat Panel Display ●Absolute maximum ratings Parameter Supply voltage Input voltage Output voltage Storage temperature range ●Package power Package TQFP64V *1 *2 Symbol VDD VIN VOUT Tstg Ratings Min. -0.3 -0.3 -0.3 -55 Max. 4.0 VDD+0.3 VDD+0.3 125 Unit V V V ℃ PD(mW) 700 1000 *2 DERATING(mW/℃) 7.0 10.0*2 *1 At temperature Ta > 25℃ Package power when mounting on the PCB board.
