Clare has developed the industry's first grey-scale organic light emitting diode (OLED) controller for commercial markets.
Platform cuts linecard development work
Legerity and Clare have unveiled a new foreign exchange office (FXO) evaluation platform that will reduce the system-level cost, board space and development time for trunk interface linecards.
Input data are shifted into an 8bit register and retained with an 8bit latch.
High voltage outputs are bidirectional switches capable of operating from various combinations of split power supplies up to 200V, such as +50/-150 or +100/-100V.
Parts are available in surface mountable, 28-lead plastic chip carrier or a 48-lead TQFP.
The blocking voltage for the analogue switch is 220V and the output on-state resistance is 22ohm with tight small signal matching resistance per channel (5% typical).
CMOS control logic offers low quiescent power consumption with an input clock frequency up to 5MHz.
Clare's unique patented SOI technology offers the ability to achieve extremely high output "off state" isolation (58dB typical at 5MHz) and high immunity to switch crosstalk (70dB typical at 5MHz).
The CPC7220 is fabricated using Clare's patented HVIC process.
The monolithic silicon features low power CMOS logic and high voltage complementary PMOS and DMOS switches, as well as some bipolar functions.
"The introduction of this part represents Clare's entry into the non-telecom high-voltage IC market space".
"We are leveraging our long history in producing high voltage ICs for telecommunication, and deploying it in new markets that need the same level of integration, on chip isolation and reliability", commented Mark Heisig, General Manager of Clare.
"Our unique technology when combined with our high voltage integrated circuit capability now offers customers cost effective solutions in many new areas such as medical imaging, printers, displays, test equipment, power management and other high voltage applications".
The CPC7220 is available in sample and production quantities.
In quantities of 1000 units the CPC7220 is priced at $9.45 with a standard lead time of 14 weeks.
