Agilent Technologies Introduces Industry's Smallest Four-port SerDes Semiconductor Chip for Fibre Channel SANs

10/23/2002 - Agilent Technologies introduced the industry's smallest four-port serializer/deserializer (SerDes) integrated circuit (IC) designed specifically for Fibre Channel storage area networking (SAN) equipment used to store and transport data between servers and larger corporate data centers. The device, at 19 mm by 19 mm, is the smallest in the industry, saving board space and costs for Fibre Channel SAN equipment manufacturers.

The Agilent HDMP-2689 quad SerDes offers 1.7-watt power consumption, the lowest in the industry, significantly lowering the overall system power requirements, and making it ideal for Fibre Channel switches, RAID (redundant array of independent disks) and JBOD (just a bunch of disks) storage systems, and high-speed backplane applications.

The Agilent four-port SerDes IC operates at 2.125 Gb/s and 1.0625 data rates and provides the interface between four fiber optic transceivers and the media access controller (MAC) or high-speed serial backplane, which are located on either a Fibre Channel motherboard or host bus adapter (HBA). The SerDes converts 8-bit or 10-bit wide parallel data to and from a serial data stream for transmission over the board's fiber optic transceiver links.

"Having shipped more than 20 million SerDes ports, Agilent has a proven track record in physical layer ICs for the Fibre Channel market," said Philip Gadd, marketing manager for Agilent's Storage and Networking Division. "Agilent co-authored the Fibre Channel specification and delivered the world's first Fibre Channel controller. Today, Agilent offers the broadest line of SAN component solutions, including Fibre Channel controllers, adapter boards, fiber optic transceivers, port bypass circuits and SerDes chips."

The Agilent HDMP-2869 quad SerDes chip provides dual-rate serial operation at 2.125 Gb/s and 1.0625 Gb/s and provides parallel-to-serial and serial-to-parallel conversion on four independent, rate-selectable channels. The device meets or exceeds all Fibre Channel jitter specs and its optional 8-bit/10-bit encoding provides additional capability on a single chip. An on-chip phase locked loop (PLL) synthesizes the high-speed transmit clock from a low-speed (106.25 MHz) reference. Each receiver's on-chip PLL synchronizes directly to the incoming data stream, providing clock and data recovery. Both the transmitter and receiver support differential I/O for fiber optic component interfaces, which minimizes crosstalk and maximizes signal integrity. Chip control and status are accessed via the media independent interface (MII) defined in IEEE 802.3.

The Agilent HDMP-2689 quad SerDes chip is based on 0.18 micron CMOS process technology and operates from a 1.8V core power supply, and 2.5V power supply for SSTL_2I/O. It includes a self test capability and is boundary-scan IEEE 1149.1 compliant. The device is supplied in a 289-pin PBGA package and combines with the Agilent HFBR-5720AL and HFBR-5720ALP SFP fiber optic transceivers to form a complete solution.
