256M Double Data Rate Synchronous DRAMA3S56D30FTPA3S56D40FTPPIN FUNCTIONCLK, /CLKInputClock: CLK and /CLK are differential clock inputs. All address and controlinput signals are sampled on the crossing of the positive edge of CLK andnegative edge of /CLK. Output (read) data is referenced to the crossings ofCLK and /CLK (both directions of crossing).CKEInputClock Enable: CKE controls Power Down and Self Refresh. Taking CKE LOW provides Precharge Power Down or Self Refresh (all banks idle),or Active Power Down (row active in any bank).Taking CKE HIGH provides Power Down exit or Self Refresh exit.After Self Refresh is started, CKE becomes asynchronous input. Power Down and Self Refresh is maintained as long as CKE is LOW./CSInputChip Select: When /CS is HIGH, any command means No Operation./RAS, /CAS, /WEInputCombination of /RAS, /CAS, /WE defines basic commands.A0-12InputA0-12 specify the Row / Column Address in conjunction with BA0,1. The Row Address is specified by A0-12. The Column Address is specified by A0-9(x8) and A0-8(x16). A10 is also used to indicate precharge option. When A10 is HIGH at a Read / Write command, an Auto Prechargeis performed. When A10 is HIGH at a Precharge command, all banks are precharged. BA0,1InputDQ0-7 (x8),DQ0-15 (x16),Input / OutputDQS (x8)Vdd, VssPower SupplyPower Supply for the memory array and peripheral circuitry.VddQ, VssQPower SupplyVddQ and VssQ are supplied to DQ, DQS buffers.Bank Address: BA0,1 specifies one of four banks to which a command is applied.BA0,1 must be set with Active, Precharge, Read, Write commands. Data Input/Output: Data busData Strobe: Output with read data, input with write data. Edge-aligned with read data, centered in write data. Used to capture write data. For the x16, LDQS corresponds to the data on DQ0-DQ7; UDQS correspond to the data on DQ8-DQ15SYMBOLTYPEDESCRIPTIONDM (x8)InputInput Data Mask: DM is an input mask signal for write data. Input data is masked when DM is sampled HIGH along with that input data during a write access. DM is sampled on both edges of DQS. Although DM pins are input only, the DM loading matches the DQand DQS loading. For the x16, LDM corresponds to the data on DQ0-DQ7; UDM corresponds to the data on DQ8-DQ15.Input / OutputVREFInputSSTL_2 reference voltage.UDQS, LDQS (x16)UDM, LDM (x16)AVR 2650 AVR 2650 harman/kardonharman/kardon 121RadioFans.CN 收音机爱 好者资料库 12-Bit, 170 MHz Video and Graphics Digitizer with 3D Comb Filter Decoder and Quad HDMI 1.4 Fast Switching Receiver PRELIMINARY ADV7844 FEATURES Quad HDMI 1.4 Fast Switching Receiver 170 MHz Video and Graphics Digitizer 3D Comb Filter Video Decoder SCART Fast Blank Support Adaptive HDMI Equaliser Integrated CEC Controller HDMI Repeater Support Advanced VBI data slicer Video and Graphics Digitizer Four 170 MHz, 12-bit ADCs, 12-channel analog input mux 525i-/625i-component analog input 525p-/625p-component progressive scan support 720p-/1080i-/1080p-component HDTV support Low refresh rates (24/25/30 Hz) support for 720p/1080p Digitizes RGB graphics up to 1600 1200 at 60 Hz (UXGA) 3D Video Decoder NTSC/PAL/SECAM color standards support NTSC/PAL 2D/3D motion detecting comb filter Advanced time-base correction (TBC) with frame synchronization Interlaced-to-progressive conversion for 525i and 625i IF compensation filters Vertical peaking and horizontal peaking filters Robust synchronization extraction for poor video source 4:1 HDMI 1.4 225 MHz Receiver Fast-Switching of HDMI ports 2:2 HEAC muxing support 2 HEAC channel support 2 Ethernet Interfaces for HEC Support SPDIF interface for ARC support. 3D Video format support including frame packing 1080p 24Hz, 720p 50 Hz, 720p 60Hz Full colorimetry support including sYCC601, Adobe RGB, Adobe YCC 601 36-/30-bit Deep Color and 24-bit color support HDCP 1.3 support with internal HDCP Keys +5V Detect and Hot plug assert for each HDMI port Full HDMI Audio Support including HBR, DSD, DST Advanced Audio mute feature Flexible digital audio output interfaces Supports up to 5 SPDIF outputs, Supports up to 4 I2S outputs General Highly flexible 36-bit pixel output interface Internal EDID RAM for HDMI and graphics Dual STDI (standard identification) function support Any-to-any, 3 3 color space conversion (CSC) matrix 2 programmable interrupt request output pins Simultaneous analog processing and HDMI monitoring APPLICATIONS Advanced TVs PDP HDTVs LCD TVs (HDTV ready) LCD/DLP rear projection HDTVs CRT HDTVs LCoS HDTVs AVR video receivers LCD/DLP front projectors HDTV STBs with PVR Projectors FUNCTIONAL BLOCK DIAGRAM 36-BIT YCbCr/RGBADV7844SCART RGB+ CVBSCVBSYCHDMI 4HDMI 3HDMI 2HDMI 1HD YPbPrINPUT MUXSD/PSYPbPrSDRAMSCART GSCART BSCART RCVBSCVBSSCARTCVBSI2S364Y/GPb/BPr/R48GRAPHICSRGBADCADCADCADCTO AUDIOPROCESSORTMDSDDCTMDSDDCTMDSDDCTMDSDDCDEEPCOLORHDMI RxHDCPKEYSSPDIFDSDSDPCLKHS/VSFIELD/DECLKHS/VSFIELD/DECLKHS/VSFIELD/DECVBS 3D YCS-VIDEOSCARTCPYPbPr525p/625p720p/1080i1080p/UXGARGBOUTPUT MUXOUTPUT MUXHBRAUDIOOUTPUT5MCLKSCLKMCLKSCLKDATADATAFASTSWITCHSPDIFHEACETHERNET 1ETHERNET 2 Figure 1.
