Second Generation Device Features Higher Performance, Smaller Size
and Lower Price MILPITAS, Calif., Aug. 18 /PRNewswire-FirstCall/ --
California Micro Devices (NASDAQ:CAMD) today introduced the latest
ESD (electrostatic discharge) protection device in the XtremeESD
family utilizing the PicoGuard XS architecture, the CM1238. It
provides 8 channels of ESD protection that meet + -15kV contact
discharge, and + -20kV air discharge per the IEC61000-4-2 standard
as well as the 100 Ohm differential impedance matching requirements
of the HDMI 1.3a and DisplayPort(TM) digital video standards. The
CM1238 utilizes the second generation of the PicoGuard XS
architecture based on a smaller diode design that enables enhanced
signal integrity, smaller form factor and lower product cost while
maintaining ESD protection at an industry leading 20kV level. It is
ideal for digital TVs, LCD displays, notebook computers, set top
boxes, and HD DVD recorders. (Photo:

electronics designers face a broad array of design challenges in
meeting consumer requirements for greater functionality and higher
performance at ever decreasing prices," stated Kyle Baker, vice
president of marketing for California Micro Devices. "The CM1238
creates customer value by providing better performance and a
smaller size at a lower price point." PicoGuard XS Impedance
Matching and Signal Integrity The CM1238 incorporates the PicoGuard
XS architecture that integrates inductors with the diodes to create
fixed point impedance matching for high speed data lines.
Traditionally, system designers must compensate for the capacitance
of the ESD protection device by adding external inductance,
eliminating capacitance under the signal traces near the ESD
device, or both. These approaches add complexity and cost, and are
printed circuit board dependent, limiting the ability to use
multiple board vendors. In many cases, this may not even be
possible, particularly if the capacitance of the device is too high
as is typical with existing 20kV ESD devices. The CM1238 eliminates
the need for these measures, providing matched impedance with no
external compensation or components required. Robust ESD Protection
Delivering robust ESD protection requires much more than achieving
compliance with industry standards. Standards define the level of
ESD a protection solution can withstand before failing, but do not
characterize the level of residual current that passes through the
diode and reaches the device under protection. Therefore, it is
important to select a device that not only complies with industry
standards, but also ensures a low clamping voltage and low residual
current. PicoGuard XS solutions feature peak clamping voltages up
to 40% lower and peak residual currents between 15% to 40% lower
than competing solutions. XtremeESD Website This ESD Resource

Product Specifications The CM1238 provides protection for four
pairs of differential channels, offering ESD protection to
IEC61000-4-2 standard + -15kV contact discharge and + - 20kV air
discharge. The integration of inductors with the ESD diodes
provides for improved ESD protection as well as outstanding signal
integrity. The signal integrity is further enhanced as a result of
the second generation PicoGuard XS architecture based on a smaller
ESD diode structure that provides the same industry leading ESD
performance, but with improved signal integrity. The reduced die
size, together with a smaller package size, results in a lower cost
compared to the first generation design. Package, Pricing and
Availability The CM1238 is available in a 0.5mm pitch, 16 lead TDFN
package (4mm x 1.7mm). Samples will be available in October with
full production scheduled for December 2009. It is priced at $0.40
each at 1,000 units. About California Micro Devices Corporation
