This chip is designed to work with Infineon IrDA compatible transceivers and all other IrDA compatible transceivers. The chip contains a clock divider circuit used to generate the 16X clock internally. This makes it very suitable for microcontroller-based embedded system design. .393 (10.0) .386 (9.8) .244 (6.2) .229 (5.8) R x 45 ° 7 ° A B 9 8 16 1 T .157 (4.0) .150 (3.8) .009 (.25) .008 (.19) .016 (.40) .049 (1.25) .050 (1.27) BSC .014 (.35) .019 (.49) .004 (0.1) .009 (.25) .068 (1.75) .054 (1.35) Dimensions in inches (mm) Notes: 1.
