ESD protection devices handle new challenges
The Picoguard XP architecture is an innovative double-clamping architecture that integrates multiple stages of ESD protection into a single device.
They represent a complete HDMI protection and signal integrity solution to support the advanced features for HDMI 1.3, including backdrive protection and electrical isolation on all signals, level shifting circuits for DDC, hot plug and CEC lines and overcurrent protection per HDMI spec for source ports (CM2030).
Slew rate limiting on the CEC lines helps to minimise ringing and EMI (electromagnetic interference), and the dynamic DDC pullups allow longer and less expensive cables to be used.
The CM2030 and CM2031 also feature multiport DDC support, eliminating the need for an external analogue switch when addressing multiple EEPROMs.
The CM2030 and CM2031 are ideal complements to the latest HDMI 1.3 transmitters/receivers from companies such as Silicon Image.
"We selected CMD's MediaGuard parts for our latest HDMI reference design and evaluationboards because they provide unmatched signal integrity, port protection and integration", stated Rob Frizzell, Director HDMI product marketing at Silicon Image, a leader in the secure distribution, presentation and storage of high definition content.
"Building on the proven success of our industry leading PicoGuard diode arrays and MediaGuard CM2020 and CM2021 HDMI solutions, these new devices provide a complete port protection and signal integrity solution to support the advanced features for HDMI 1.3", stated Joe Salvador, Director of Marketing for Computing and Digital Consumer Products at California Micro Devices.
The CM2030 and CM2031 are available in space saving 38-pin TSSOP packages.
They are currently sampling, with production scheduled for Q4 of this year.
Pricing starts at $1.31 each in 1000 units for the CM2030, and at $1.29 each in 1000 units for the CM2031.
