Hot-pluggable transceiver for Fibre Channel
Agilent Technologies has announced volume availability of its 2Gbit/s small-form-pluggable (SFP) fibre-optic transceiver for Fibre Channel storage area networks (SANs).
The Agilent HDMP-2689 quad SerDes offers 1.7W 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 and 1.0625Gbit/s datarates and provides the interface between four fibre-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 or 10bit wide parallel data to and from a serial datastream for transmission over the board's fibre-optic transceiver links.

IR transceiver slims down to fit latest PDAs
Agilent Technologies has announced a new serial infra-red (SIR) transceiver that is ideal for new-generation personal information devices, such as PDAs, which are becoming increasingly thinner.
"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, fibre-optic transceivers, port bypass circuits and serdes chips".
The Agilent HDMP-2869 quad serdes chip provides dual-rate serial operation at 2.125 and 1.0625Gbit/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 8/10bit encoding provides additional capability on a single chip.
An on-chip phase locked loop (PLL) synthesises the high-speed transmit clock from a low-speed (106.25MHz) reference.
Each receiver's on-chip PLL synchronises 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 minimises crosstalk and maximises signal integrity.
Chip control and status are accessed via the media independent interface (MII) defined in IEEE802.3.
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 IEEE1149.1 compliant.
The device is supplied in a 289-pin PBGA package and combines with the Agilent HFBR-5720AL and HFBR-5720ALP SFP fibre-optic transceivers to form a complete solution. Request a free brochure from Avago Technologies ...
