| Micrel Rolls Out Four New IC Solutions For Embedded and Industrial
Ethernet Appl | | | |
San Jose, Calif. — Micrel Inc., announced that it has rolled out four new
Ethernet IC solutions. The KSZ884x series is part of the 2-port and 3-port Switch/Repeater family launched in June
and July of 2005 and round out the Company’s Embedded Ethernet offerings. Micrel’s new KSZ8842-PMQL, KZS8841-PMQL,
KSZ8841-16MQL and the KSZ8841-32MQL are all aimed at the embedded and industrial Ethernet markets. The new ICs are
currently sampling, with volume quantities available in the fourth quarter of 2005. The chips are offered in
standard and RoHS compliant versions.
By choosing an off-chip Switch or Repeater IC solution, engineers now can
free up processors or FPGAs to perform tasks other than managing Ethernet Packets. Designers also have the
capability to replace two single port controllers connected to a processor or two single-port controllers and FPGA
connected to a processor with a single 2-port switch. In addition, pin-to-pin compatibility across devices allows
customers to layout their boards for dual-port applications while servicing current single-port needs. Next
generation applications can then use the same board and the dual port devices, thereby saving both time and
money.
The KSZ8842-PMQL is a 2-port Ethernet Switch/Repeater featuring a third port, 32 bit/33MHz
PCI v2.2 Host Processor interface. The KZS8841-PMQL, KSZ8841-16MQL and the KSZ8841-32MQL are single-port MAC plus
PHY controllers with 32 bit/33MHz PCI Host Interface, 8 or 16 bit generic Host Bus Interface or 32-bit generic Host
Interface, respectively. Micrel’s new ICs offer another industry first, providing any processor or FPGA with an 8,
16, or 32-bit generic bus or 32-bit PCI bus with Switch or Repeater capability. The Dual port devices are ideally
suited for VoIP Phones and ATA applications, offering four priority queues per port and special filtering
capabilities to reduce traffic congestion. This ensures superior voice quality — a key requirement in this explosive
market.
The dual port devices have the lowest port-to-port latency in the Industry, making each
device ideal for daisy-chaining applications such as Video Phones or Industrial or ATE Equipment. The solutions also
feature Micrel’s patented mixed signal PHY capability resulting in extremely low power consumption across the
product family. The KSZ8842M generic bus and switch parts are pin-to-pin compatible with the KSZ8841M Ethernet
Controller parts, while the KSZ8842-PMQL switch and PCI bus is pin-to-pin compatible with the KSZ8841-PMQL Ethernet
Controller allowing parts to be interchangeable, depending upon a customer’s applications and requirements.
All devices feature LinkMDTM, a cable diagnostic package that enables diagnosis of common cabling
problems. Rapid diagnosis of cabling conditions, including distance to fault information, results in reduced
customer calls (truck rolls or product returns) and IT service requests. The ICs also offer HP Auto-MDIX, a robust
solution for automatic detection and correction for straight-through or crossover cables.
“Since
Ethernet is such an easy to use and widely used networking solution, it makes sense for the technology to expand
well beyond the SOHO networking and Enterprise spaces,” noted Grahame Cooney, Director, Micrel Ethernet group.
“Today, Ethernet is expanding into industrial applications on the factory floor and into other areas of the home to
connect IP set-top boxes, TVs, multimedia hubs, ATAs and even refrigerators. This trend will accelerate and, with
Residential Ethernet becoming a reality in the not too distant future, it will create a demand for millions of new
Ethernet ports. Micrel’s latest chip offerings allow us to meet our customers’ needs for current and emerging
Ethernet applications.” |
