| SiI 2024 Fibre Channel Quad SerDes Silicon Image's SiI 2024 Quad serializer/deserializer (SerDes) is capable of transmitting and receiving four independent channels of data at 1.0625 and 2.125 gigabits-per-second (Gbps). Targeted at Fibre Channel applications, the SiI 2024 Quad SerDes is designed for power, performance and price. Making use of a robust CMOS design that significantly reduces power dissipation and jitter, the SiI 2024 provides a low-cost solution for applications that require multiple-channel, high-performance Fibre Channel SerDes. By offering four integrated, low-power SerDes in one package, the SiI 2024 reduces board space and power requirements traditionally needed for Fibre Channel SerDes. On a per-channel basis, the SiI 2024 supports selectable transmit and receive data rates for automatic speed negotiation. It also utilizes 10-bit SSTL_2-compatible interfaces for each channel's parallel data input/output. For added flexibility in some system applications, the SiI 2024 offers pre-emphasis and voltage swing control on the serial transmit ports. The SiI 2024 is available in a 324-pin, 23x23mm PBGA package and supports JTAG for improved testability. The SiI 2024 SerDes leverages much of the circuit innovation at the physical layer of Silicon Image's proprietary, reduced overhead Multilayer Serial Link (MSLTM) architecture, pioneered and proven through the company's market-leading PanelLink(R) and SATALinkTM products. MSL technology is a multi-layer approach to providing robust, costeffective, multi-gigabit semiconductor solutions on a single chip for high-bandwidth applications.
