Description
The HSDL-7000 performs the modulation/demodulation function used to both encode and decode the electrical pulses from the IR transceiver. These pulses are then sent to a standard UART which has a BAUDOUT signal available externally. This signal is 16 times the selected baud rate. In applications where the 16XCLK is not available, an external means of generating the 16XCLK must be designed.

Features
• Compliant with IrDA physical layer specs
• Interfaces with IrDA compliant SIR (115Kbps) transceiver
• 1 Micron CMOS gate array
• Used in conjunction with standard 16550 UART

Applications
Interfaces with SIR infrared transceivers to perform:
• Serial half-duplex data transfer between: Notebook computers Subnotebooks Desktops PCs PDAs Printers Other peripheral devices
• Telecom applications in: Modems Fax machines Pagers Phones
• Industrial applications in: Data collection devices
• Medical applications in: Patient and pharmaceutical data collection
