Inphi(R) Corporation's 1348TA First to Exceed IEEE 10GBASE-Long Reach Multimode Standard

Inphi(R) Corporation (www.inphi-corp.com), the world leader in
performance and signal integrity, unveiled the industry's first 10
Gbps integrated Transimpedance Amplifier / Automatic Gain Control
(TIA/AGC) to meet or exceed every requirement of the IEEE 802.3aq,
10GBASE-LRM (10G LRM) standard, the 1348TA S03D, making it one of the
first viable solutions for 10G SFP+ Long Reach Multimode applications.

"Inphi's 1348TA is the type of breakthrough product that should
speed the migration to 10 Gbps Ethernet long reach multi-mode
transmissions, enabling a new class of performance for enterprise
networks and applications," said Dr. Jon Anderson, vice president
research and development for Opnext, Inc.'s Pluggable Business Unit.
"As communications and computing platforms continue moving to higher
speeds, Inphi is delivering the performance design engineers need."

Part of Inphi's PhyOptik(R) product family, the 1348TA S03D, which
debuted during ECOC 2007 (Booth #12029), has the highest gain in its
class, 6 K OMEGA differential, resulting high output voltage amplitude
that meets the SFP+ requirements over the entire operating range from
-11 dBm (optical modulation amplitude) to + 3dBm (optical modulation
amplitude) without the need for an additional buffer amp, exceeding
IEEE 10GBASE-LRM standards. Unique to the 1348TA, this powerful
performance provides design engineers with a plug-and-play solution
that is lower cost than any alternative solution.

The integrated TIA/ACG passed stringent testing to ensure complete
interoperability with all leading Electronic Dispersion Compensation
(EDC) chips in the market, and is expected to speed deployment of 10
Gbps Ethernet (10 GbE) serial transmission over all grades of low cost
multimode fiber. Enterprise based data transmission previously
deployed over multi-mode fiber (MMF) at Ethernet data rates up to 1
Gbps, is rapidly transitioning 10 GbE using the same installed fiber
base. The 10G LRM standard simplifies extended reach 10 GbE data
transmission over legacy MMF by employing new electronic dispersion
compensation (EDC) technology. The demand to convert slower, legacy
data links to 10G LRM links is expected to reach over 1 million ports
by 2010.

"Market leaders like Opnext continue to rely on Inphi for
components that transport, store, and deliver high-speed data for the
world's most innovative high-performance communications and computing
systems," said Loi Nguyen, founder and vice president of technology
for Inphi. "The 1348TA delivers sustainable competitive advantages for
customers designing next generation high-speed systems."

Based upon the highly successful 1348TA-S01D TIA/AGC, which is
widely used in X2 and XFP applications, the 1348TA-S03D extends the
power supply operating range of the 1348TA to +/- 10% and output
electrostatic discharge protection to over 1 KV (Human Body Model),
two critical requirements for SFP+ applications, while achieving
error-free operation from -11 dBm (Optical Modulation Amplitude) to
greater than 3 dBm (Optical Modulation Amplitude) under all stress
conditions per IEEE 802.3aq, 10G LRM standards. The 1348TA's Thru
Wafer Via ensures reliable grounding, eliminating the need for ground
bonds.

Price and Availability

The Inphi 1348TA is available in engineering samples with volume
shipments expected to begin in Q1'08.
