Ideal for HDMI(TM) and DisplayPort(TM) Applications in Digital
Consumer, PC and Mobile Applications MILPITAS, Calif., Feb. 25
/PRNewswire-FirstCall/ -- California Micro Devices (NASDAQ:CAMD)
today introduced the latest ESD (electrostatic discharge)
protection devices in the XtremeESD(R) family, the CM1235 and
CM1236. Both devices incorporate the award winning PicoGuard XS
architecture that features integrated impedance matching with
improved ESD performance. They feature 8 channels of ESD protection
that meet the 8kV contact discharge requirement of the IEC61000-4-2
standard, while also meeting the 100 Ohm differential impedance
matching requirements of the HDMI(TM) 1.3a and DisplayPort(TM)
digital video standards. They are ideal for digital TVs, LCD
displays, notebook computers, set top boxes and Blu-Ray recorders
and players. The small size of the CM1235 also makes it ideal for
portable applications including mobile phones, camcorders and
digital still cameras. (Photo:

member of the PicoGuard XS family, the CM1233, was recently awarded
Electronic Products magazine's coveted "Product of the Year" award.
The CM1235 offers the same impedance matching and 8kV protection as
the CM1233, but in a footprint that is 70 percent smaller. The
CM1236 is pin-compatible with the CM1233, but is an improved design
offering even better impedance matching. "As data rates continue to
increase, the ability to add ESD protection without compromising
signal integrity is extremely important," stated Joe Salvador,
director of marketing for computing and digital consumer products.
"The PicoGuard XS architecture enables ESD devices that are small
enough for mobile phone applications while providing signal
integrity that exceeds the most stringent requirements of high
definition televisions and PC monitors." CMD's PicoGuard XS
Architecture The CM1235 and CM1236 are based on the PicoGuard XS
architecture that integrates inductors with the ESD diodes to
improve 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
PC board dependent, limiting the ability to use multiple board
vendors. The CM1235 and CM1236 eliminate the need for these
measures, providing matched impedance with no external compensation
or components required, in a board-independent footprint. CM1235
and CM1236 - Main Features The CM1235 and CM1236 provide protection
for four pairs of differential channels, offering 8kV contact
discharge ESD protection in accordance with the IEC61000-4-2
standard. The integration of inductors with the ESD diodes enhances
ESD protection as well as ensuring outstanding signal integrity.
Compared with industry leading single stage ESD diode arrays, they
offer: -- Greater than 40% reduction in peak clamping voltage --
80% reduction in peak residual current -- Greater than 10%
reduction in total energy reaching the protected device -- 100 Ohm
differential impedance matching with no external compensation
required -- Close matching between lines -- No Vp connection,
eliminating backdrive and simplifying layout -- Compact 16 pin TDFN
