IFSYS-7000 IrDATM SIR Endec Chip (SOP8)  
Product Brief  
The IFSYS -7000 is designed to be used as an add on peripheral IC for any  
SIR IrDATM compliant optoelectronic transceiver. It is ideally suited to  
applications requiring low cost and low power communication based on the  
IrDATM standard. IFSYS-7000 does not require an external crystal; it utilizes  
a 16X clock from the host system to provide the 16X baud rate clock for both  
encoding and decoding, using infrared pulse widths of 3/16th the bit time.  
iFoundry’s IFSYS-7000 supports the full complement of IrDATM V1.1 baud  
rates, from 9,600 bps right up to 115,200bps.  
IFSYS-7000
