Product Description
Note: CMDs 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 applica-
tions in which power consumption and noise immunity are critical considerations.
CMDs P/Active DN005 Schottky Diode High Speed Bus Terminator
is specifically designed to minimize undershoot/over-
shoot 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 simulta-
neously 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 space-
critical 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
