(10 pcs) PACDN005Q (R016001QS) P/ACTIVE SCHOTTKY DIODE HIGH SPEED BUS TERMINATOR

This listing is for 10 pcs.

Product Description Note: CMDÂ’s P/Active DN005 Schottky Diode High Speed Bus Terminator is an upgraded version of the original PDN001 or IPEC DN001 Diode Array. PACDN005 provides minimized lead inductance and parasitic capacitive effects (with added ground pins), improved forward voltage and crosstalk attributes, and excellent termination performance characteristics at high data transmission rates. The PACDN005 is recommended for all new designs. Reflections on high speed data lines lead to undershoot and overshoot disturbances which may result in improper system operation. Resistor terminations, when used to terminate high speed data lines, increase power consumption and degrade output (high) levels resulting in reduced noise immunity. Schottky diode termination is the best overall solution for applications in which power consumption and noise immunity are critical considerations. CMDÂ’s P/Active DN005 Schottky Diode High Speed Bus Terminator† is specifically designed to minimize undershoot/overshoot disturbances caused by reflection noise on high speed bus lines such as v2.1 66MHz PCI buses, all varieties of RISC embedded processor/control local buses, synchronous DRAM, and other high speed memory bus termination applications. This highly integrated Schottky diode network provides very effective termination performance for high speed data lines under variable loading conditions. The device supports up to 18 terminated lines per package each of which can be simultaneously clamped to both ground and power supply rail. A typical bus termination application will utilize three PAC DN005 devices to replace approximately 50 conventional Schottky diode pairs; thus providing significant reductions in component and assembly costs, improvements in manufacturing efficiency and reliability, and savings in allocated board area for spacecritical designs. 

Applications: • PCI v2.1 Bus Termination for Intel-based Pentium® and Pentium Pro systems • Local high speed bus termination for all popular RISC and embedded microprocessor applications • High speed memory and SDRAM Memory Bus Termination P/ACTIVE SCHOTTKY DIODE HIGH SPEED BUS TERMINATOR Refer to AP-201 Termination Application Note for further information.
