- Programmable "Back-End" I/Os
• Flexible:
- Serial-to-parallel/parallel-to-serial conversion rates from 1:1 to 1:20
- Embedded or separately transmitted clocks
- Point-to-point, multi-point, multi-drop supportDescriptionThe QuickSD™ family of Bus LVDS SERDES Embedded Standard Products (ESPs) QL84SD is the first complete solution for developing customized high-speed serial communications applications. QuickSD devices QL84SD integrate multichannel serial communications links with clock/data recovery, embedded memory, multiply/accumulate blocks, customizable logic, and programmable I/Os.
The embedded portion of the QL84SD contains highperformance, Bus LVDS transceivers that deliver up to 8 Gb/s serial data transfer rate for fast chip-to-chip, board-to-board and box-to-box communications. The customizable portion of the device consists of 658,000 system gates of programmable logic and 83,000 bits of dual-port SRAM.
QuickSD devices QL84SD are designed to support both transmit and receive requirements in a single chip, thereby providing multiple-channel support in a variety of modes and translation widths. This makes the devices ideal for applications where performance is critical and customization is required. Examples of QL84SD include 3G wireless base stations, telecom switches, Internet routers, and video transmission systems.
compression rates of QL84SD, including 1:1, 1:4, 1:7, 1:8 with an external clock and 1:10 and 1:20 with an embedded clock. This "back-end" flexibility allows the programmable fabric and embedded memory to easily implement a wide range of communication standards and other functions including Utopia II, Utopia III, Utopia IV, ATM and SONET framers, PCI interfaces, SDRAM controllers and network processor interfaces.
