Packages (DIPs)

California Micro Devices Corporation (CAMD) (Nasdaq:CAMD) today announced four differential terminator networks, PRN103, PRN153, PRN125 and PRN155, which are drop in replacements for traditional thick film resistor networks.

These highly integrated resistor arrays provide a total of 27 resistors in a single package. They are manufactured using advanced thin film technology. Thin film networks offer significant advantages over conventional thick film processes in terms of tighter absolute tolerance and resistor to resistor matching, lower temperature coefficients, greater long-term stability, and lower noise. Integrated thin film networks also offer the benefits of board space savings, reduced assembly costs and increased reliability when compared to discrete component solutions.

PRN103, PRN153, PRN125 and PRN155 are ideally suited for eliminating transition line effects on high-speed data lines on a special bus known as SCSI (Small Computer Systems Interface). This bus is quite popular in high-performance workstations and servers. Data signals transmitted at high speeds and high frequencies generate reflection and ringing effects, unless there are impedance matching terminations on the signal path. Proper resistor termination requires a resistor with tight tolerances whose value closely matches the characteristic impedance of the transmission line.

These resistor networks provide a cost-effective and space-saving alternative to discrete components. The PRN103 and PRN125 are available in a 20-pin SOIC package. The PRN153 and PRN155 are available in 20-pin DIP packages. All four devices can replace existing thick film networks without system redesign or modification Pricing for the devices in 10K quantities is as follows: PRN103, $0.60; PRN153, $0.71; PRN125, $0.60; and PRN155, $0.71. Samples are available now. Production time is 4-6 weeks ARO.
