IFSYS-7000 IrDA

SIR Endec Chip (SOP8) Product Brief

The IFSYS -7000 is designed to be used as an add on peripheral IC for any

SIR IrDA

compliant optoelectronic transceiver. It is ideally suited to

applications requiring low cost and low power communication based on the

IrDA

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

the bit time.

iFoundry’s IFSYS-7000 supports the full complement of IrDA

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

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
