California Micro Devices Announces New PicoGuard(R) Low Capacitance ESD Protection
Array for High Speed Serial Interfaces
MILPITAS, Calif., Aug. 18 /PRNewswire-AsiaNet/ --
CM6100 Provides Robust ESD Protection for Mobile Handsets and
Other Portable Applications
California Micro Devices (Nasdaq: CAMD) today announced the PicoGuard
CM6100, a low capacitance electrostatic discharge (ESD) device providing two
channels of 15 kV protection for USB 2.0 Hi-Speed interfaces and for LVDS
(low voltage differential signal) and emerging serial interfaces such as
MIPI(R) (Mobile Industry Processor Interface) used in handsets and other
mobile devices. The CM6100 is based on CMD's PicoGuard line of ESD protection
products, providing industry leading low levels of dynamic resistance,
clamping voltage and insertion loss. Utilizing a space efficient 0.4mm pitch
chip scale package (CSP), the CM6100 combines industry leading performance
with significant space and cost savings to deliver enhanced customer value
for today's most advanced mobile handset designs.
"With strong consumer demand for smart phones, handset designers have to
deal with providing robust ESD protection for an increasing number of high
speed serial data interfaces, while managing their designs within tight form
factor and bill of material budgets," said Kyle Baker, vice president of
marketing for California Micro Devices. "The PicoGuard CM6100 simplifies this
design challenge by offering robust protection and superior signal integrity
in a compact, low cost package."
Differential Pair Protection
High speed serial interfaces such as USB and MIPI(R) use pairs of low
voltage differential lines to communicate at very high speed between the
baseband processor and external USB peripherals or internal high resolution
displays and cameras. These interfaces are highly susceptible to ESD damage
and require a high level of digital signal integrity. This can be a
challenging tradeoff for designers using existing ESD solutions. Their high
levels of capacitance, necessary for them to achieve robust ESD protection,
can interfere with sensitive digital signal integrity. The CM6100 is the
industry's first solution that provides robust 15kV air discharge ESD
protection with sub 1.5pF capacitance, meeting the requirements for these
high speed serial interfaces.
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. The CM6100 features industry leading low dynamic
resistance and clamping voltage specifications, important system level
considerations that define how quickly the internal diode reacts to an ESD
strike and how much residual current passes through the protection device.
Device Specifications
The CM6100 provides protection for two differential channels, offering
ESD protection + -15kV contact discharge per the IEC61000-4-2 standard. Key
features include:
- Very low line capacitance (<1.5 pF)
- Industry leading 15 kV air discharge ESD protection
- Low dynamic resistance of 0.7 ohm
- Low 9.8v typical clamping voltage
- Low insertion loss
- Compact, easy to route form factor
- Low cost chip scale packaging
Packaging, Pricing and Availability
The CM6100 is available in 0.4mm pitch CSP (0.8mm x 0.8mm). Samples are
available now and are priced at US$0.08 each in quantities of 1000 units. The
device is currently shipping in mass production.
