Abstract: High-speed and low-speed data converters serve critical functions in modern broadband mobile radios. This application note outlines how todetermine high-speed data converter performance requirements in baseband sampling radio architectures. Also, system partition strategies andadvantages are outlined when considering a high-speed analog front-end (AFE) solution.

SL811开发资料_包含源程序_电路图_芯片资料:SL811HS Embedded USB Host/Slave Controller.The SL811HS is an Embedded USB Host/Slave Controller capable of communicate with either full-speed or low-speed USB peripherals. The SL811HS can interface to devices such as microprocessors, microcontrollers, DSPs, or directly to a variety of buses such as ISA, PCMCIA, and others. The SL811HS USB Host Controller conforms to USB Specification 1.1.The SL811HS USB Host/Slave Controller incorporates USB Serial Interface functionality along with internal full-/low-speed transceivers.The SL811HS supports and operates in USB full-speed mode at 12 Mbps, or at low-speed 1.5-Mbps mode.The SL811HS data port and microprocessor interface provide an 8-bit data path I/O or DMA bidirectional, with interrupt support to allow easy interface to standard microprocessors or microcontrollers such as Motorola or Intel CPUs and many others. Internally,the SL811HS contains a 256-byte RAM data buffer which is used for control registers and data buffer.The available package types offered are a 28-pin PLCC (SL811HS) and a 48-pin TQFP package (SL811HST-AC). Both packages operate at 3.3 VDC. The I/O interface logic is 5V-tolerant.

For nearly a hundred years telecommunications provided mainly voice services and very low speed data (telegraph and telex). With the advent of the Internet, several data services became mainstream in telecommunications; to the point that voice is becoming an accessory to IP-centric data networks. Today, high-speed data services are already part of our daily lives at work and at home (web surfing, e-mail, virtual private networks, VoIP, virtual meetings, chats...). The demand for high-speed data services will grow even more with the increasing number of people telecommuting.

The SL11RIDE is a low cost, high speed Universal Serial Bus RISC based Controller board. It contains a 16-bit RISC processor with built in SL11RIDE ROM to greatly reduce firmware development efforts. Its serial flash EEPROM interface offers low cost storage for USB device configuration and customer product specific functions. New functions can be programmed into the I2C by downloading it from a USB Host PC. This unique architecture provides the ability to upgrade products, in the field, without changing the peripheral hardware.

Supplemental information for a high-speed serial bus that integrates well with most IEEE standard 32-bit and 64-bit parallel buses is specified. It is intended to extend the usefulness of a low-cost interconnect between external peripherals, IEEE Std 1394-1995. This standard follows the ISO/IEC 13213:1994 Command and Status Register (CSR) architecture.
