The NBSG16 supports high-speed backplane acceleration and paves the way for optical

ON Semiconductor (Nasdaq: ONNN) today announced initial engineering sampling of the first
member of its new GigaCom family of silicon germanium (SiGe) advanced devices. The NBSG16,
the name for the new device, is a next-generation integrated circuit (IC) designed
specifically to support high-speed broadband applications at an operating speed of up to 12
Gigabits per second (Gbps).

This innovative device is a 2.5 to 3.3Vdc SiGe differential receiver/driver that will support
the high-performance needs of networking equipment manufacturers designing gear capable of
OC-192 SONET and 10 Gigabit Ethernet (10-GbE) speeds. The NBSG16 improves data rates
three-fold over currently available offerings. This SiGe device also introduces an innovative
capability called Reduced Swing ECL (RSECL) - enabling 400mV output levels. This function is
a significant improvement over the switching speeds of 500mV output offerings on the market

"Customers have responded enthusiastically to the NBSG16 engineering samples," said Mike
Radhanauth, ON Semiconductor Broadband Business Group marketing director. "The device
provides engineers an innovative package design and the performance characteristics required
for the next generation of networking gear."

The general distribution of NBSG16 engineering samples is planned for July and will allow
evaluation and performance upgrades within a broad range of high-speed applications. ON
Semiconductor's full volume production of the NBSG16 is currently scheduled for late third

The timely introduction of the NBSG16 catapults Phoenix-based ON Semiconductor forward in the
race to deliver high performance ICs for advanced high-speed broadband applications. From a
practical standpoint, the NBSG16 also maintains the manufacturability and price-point
required for cost-effective mass production.

Pricing for the NBSG16 is estimated to be $20 for 10,000 units. This provides a substantial
cost savings over comparable gallium arsenide devices expected to sell for five- to six-times
more. In many instances, the NBSG16 offers additional cost savings by reducing the overall
component requirements utilized within specific high-speed applications.


ON Semiconductor designed the NBSG16 specifically as a line driver/receiver for backplane
acceleration. However, the product's versatile design will also enable engineers to deploy
the device into advanced optical networking gear such as an optical networking laser driver.

"The optical networking space continues to grow - especially in metropolitan networks," said
Radhanauth. "The laser driver is a key component in an optical network's fibre optic module
(FOM). For this application, the NBSG16 derivative with variable swing - which is currently
under development - will allow design engineers to implement laser drivers in a discrete
fashion far more economically than using off-the-shelf ones."

In addition to use in optical networking OLTs and ONUs, OC-192 SONET and 10 Gigabit Ethernet,
the NBSG16 can be utilised within ultra high-speed terabit routers, DSLAM concentrators,
fibre-optic modules, and advanced test equipment.

Features and Benefits

The NBSG16 has an operating range of 2.375 to 3.6 Vdc with 1.6 Vdc derivatives planned for
future release. Another advantage of this device is that it is compatible with existing PECL
2.5 to 3.3 Vdc devices such as ON Semiconductor's existing MC10/100 series.

Its versatile AnyLevel input structure allows for direct interface to multiple voltage levels
like LVDS, PECL, CML, CMOS, HSTL and GTS, etc. This feature enables designers to
translate between different input and output voltage levels. Also, low jitter generation of
less than 1 ps RMS increases the maximum operating frequency for fast data transmission.
With high-speed demands increasing in today's broadband market, it is important to provide
excellent signal integrity, impedance control, and board space within equipment design. To
assist in meeting these objectives, the required 50 ohm input termination resistors have been
integrated within the NBSG16.

As for packaging, the initial device offering will be assembled within standard sixteen ball
flip chip ball grid array (FCBGA) to maximise its bandwidth and thermal performance
capabilities. This new device also reduces power consumption by limiting the supply current
to 25mA.
