SIR Endec Chip (SOP8) Product Brief
The IFSYS -7000 is designed to be used as an add on peripheral IC for any
SIR IrDA
TM
compliant optoelectronic transceiver. It is ideally suited to
applications requiring low cost and low power communication based on the
IrDA
TM
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 3/16 th the bit time.
iFoundry’s IFSYS-7000 supports the full complement of IrDA
TM
V1.1 baud
rates, from 9,600 bps right up to 115,200bps.
Key features
Wide voltage operating range (2.7V – 5.5V). Single power supply
input.
Small form factor 8-pin SOP package.
Operates in 3/16 th
mode transmit pulse width.
Operates from an external 16X clock input from the host processor
or UART. Supports the following speeds:
•
9,600bps
•
19,200bps
•
38,400bps
•
57,600bps
•
115,200bps
