PACRG
P/Active
High Performance GTL/ECL Local Termination Network
Features
Designed especially for Pentium Pro and RISC-
based computers/servers
Provides high speed bus termination
Reduces ground bounce with center ground
pin placement
Terminates 22 lines in a QSOP package
Saves board space and reduces assembly cost
Product Description
CAMD’s P/Active RG GTL+ Local Bus Terminator is ideal
for Pentium Pro and related high speed bus termination
applications where a resistor approach is deemed suitable.
This device also meets the high-speed bus termination
demands of microprocessors like Motorola’s PowerPC,
DEC’s Alpha, Sun’s SPARC, and SGI’s MIPs processor, as
well as other high performance RISC processors for
embedded control applications.
The PACRG offers 22 terminations per package and meets
all related Intel specifications for Pentium Pro termination
requirements. Four popular values are available for a
variety of bus termination applications and line impedance
requirements: 47, 50, 56 and 68 ohms.
Applications
Pentium Pro servers
Pentium Pro desk top systems
GTL, ECL terminator for embedded
processor busses
PIN DIAGRAM
Refer to AP-201 Termination Application Note and AP-203 GTL+
Termination Application Note for further information.
The P/Active RG Termination Networks provide high
performance, high reliability, and low cost through manu-
facturing efficiency. The termination resistor elements are
fabricated using proprietary state-of-the-art thin film
technology. CAMD’s highly integrated solution is silicon-
based and has the same enhanced reliability characteris-
tics as today’s microprocessor products. The thin film
resistors have very high stability over a wide temperature
range, over applied voltage, and over life. In addition, the
QSOP industry standard packaging is manufacturing-
friendly and yields the high reliability of other semiconduc-
tor components. The P/Active RG Pentium Pro Termination
Network provides a complete 300 point termination
solution in only 14 QSOP packages.
