Features
- Stable resistor-capacitor network 9 terminating lines/package Saves board space, reduces assembly cost, simplifies routing ESD protected Miniature QSOP package Product Description Advanced, high-speed parallel ports, conforming to the IEEE 1284 standard, are used to provide communica- tions with external devices such as tape back-up drives, ZIP drives, printers, parallel port SCSI adapters, external LAN adapters, scanners, and other PC peripherals. These advanced ports support bi-directional transfers to 2MB/sec and above. To support these data rates, the IEEE 1284 standard recommends a combined termina- tion, 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 the need to include a filter on the parallel port.
Applications
ECP/EPP Parallel Port termination EMI/RFI Filter Notebook and Desktop computers Engineering Workstations and Servers C1210600 SCHEMATIC CONFIGURATION The PRC1284 addresses all of these requirements by providing a nine line, IEEE 1284 compliant network in a thin film integrated circuit. Two of these networks replace 54 discrete components and provide a complete parallel port termination. CAMD’s PRC1284 Parallel Port Termination Network is a convenient single function which includes pull-up, series termination, and an EMI filter capacitor. The resistors and capacitors are fabricated using proprietary state-of- the-art thin film technology.
