方案关键器件表

NT5CB128M8DN-DH参数

The 1Gb Double-Data-Rate-3 (DDR3/L) B-die DRAMs is double data rate architecture to achieve high-speed operation. Itis internally configured as an eight bank DRAM.

The 1Gb chip is organized as 16Mbit x 8 I/Os x 8 banks or 8Mbit x 16 I/Os x 8 bank devices. These synchronous devicesachieve high speed double-data-rate transfer rates of up to 2133 Mb/sec/pin for generalapplications.

The chip is designed to comply with all key DDR3/L DRAM key features and all of the control and address inputs aresynchronized with a pair of externally supplied differential clocks. Inputs are latched at the cross point of differential clocks

(CK rising and
falling). All I/Os are synchronized with a single ended DQS or differential DQS pair in a sourcesynchronous fashion.

These devices operate with a single 1.5V ± 0.075V &1.35V -0.067/+0.1V power supply and are available in BGA packages.

MSR2112参数

The MSR2112 GPS/GLONASS RF receiver is a highly-integrated RFIC which employs a single down-conversion

radio architecture to translate L1 GPS/GLONASS signal down to a fixed low IF for digital sampling and

demodulation. The MStar GPS/GLONASS RFIC in conjunction with MStar advanced GPS/GLONASS baseband (BB)

processor offers the industry’s best performance and most cost-effective GPS/GLONASS solutions which are.suitable for mobile applications, such as handsets and personal digital assistants (PDAs).

TC58NVG0S3ETA00参数

he TC58NVG0S3E is a single 3.3V 1 Gbit (1,107,296,256 bits) NAND Electrically Erasable and Programmable

Read-Only Memory (NAND E2PROM) organized as (2048 + 64) bytes × 64 pages × 1024blocks.

The device has two 2112-byte static registers which allow program and read data to be transferred between theregister and the memory cell array in 2112-byte increments. The Erase operation is implemented in a single blockunit (128 Kbytes + 4 Kbytes: 2112 bytes × 64 pages).

The TC58NVG0S3E is a serial-type memory device which utilizes the I/O pins for both address and data

input/output as well as for command inputs. The Erase and Program operations are automatically executed makingthe device most suitable for applications such as solid-state file storage, voice recording, image file memory for stillcameras and other systems which require high-density non-volatile memory data storage.

MST701-LF参数

The MST701 is a high quality ASIC for NTSC/PAL/SECAM Video Decoder application. It receives analog

NTSC/PAL/SECAM CVBS and S-Video inputs from TV tuners, DVD or VCR sources, including weak and distorted

signals, as well as analog YCbCr input from HDTV/SDTV systems. Automatic gain control (AGC) and 10-bit

3-channel A/D converters provide high resolution video quantization. With automatic video source and mode

detection, users can easily switch and adjust variety of signal sources. Multiple internal adaptive PLLs precisely

extract pixel clock from video source and perform sharp color demodulation. Built-in line-buffer supports

adaptive 2-D comb-filter, 2-D sharpening, and synchronization stabler in a condense manner. The output

format of MST701 supports CCIR656 TTL output for 480i, 576i, 480P, and 576P.
