PAC1284 CALIFORNIA MICRO DEVICES P/ACTIVE IEEE 1284 ECP/EPP TERMINATION NETWORK Applications ECP/EPP Parallel Port termination EMI/RFI filter Notebook and Desktop computers Engineering Workstations and Servers Features Stable resistor-capacitor network 9 terminating lines/package Saves board space, reduces assembly cost, simplifies routing ESD protected Miniature QSOP package Product Description Note: CAMDs P/Active 1284 Parallel Port Termination Network is an upgraded version of the original PRC1284 or IPEC1284 which provides ESD protection, minimized lead inductance and parasitic capacitive effects, and improved crosstalk and filter performance characteristics at high data transmission rates. The PAC1284 is recommended for all new designs. Advanced, enhanced high-speed parallel ports, conforming to the IEEE 1284 standard, are used to provide communications with external devices such as tape back-up drives, ZIP drives, printers, parallel port SCSI adapters, external LAN adapters, scanners, video capture, and other PC peripherals. These advanced ports also support bi-directional transfers to 2MB/sec. To effectively support these higher transfer data rates, the IEEE 1284 standard recommends a combined termination, pull-up filter network between the driver/receiver and the cable at both ends of the parallel port interface. In addition, government EMC compatibility requirements impose strict filtering on the parallel port. CAMDs P/Active 1284 Parallel Port Termination Network addresses all of these requirements by providing a nine line, IEEE 1284 compliant network, in a thin film integrated circuit. Two of these devices replace up to 54 discrete components and provide a complete parallel port termination solution for spacecritical applications. CAMDs P/Active technology provides high reliability and low cost through manufacturing efficiency. The P/Active 1284 includes pull-up, series termination, an EMI filter capacitor, and ESD protection for the capacitors. The resistors and capacitors are fabricated using proprietary state-of-the-art thin film technology.1 CAMDs solution is silicon-based and has the same reliability characteristics as todays microprocessor products. The device is protected from ESD discharges to over 4,000 volts.
