The 8S89872 is a high-speed Differential-to-LVDS Buffer/Divider with Internal Termination. The 8S89872 has a selectable ÷2, ÷4, ÷8, ÷16 output dividers. The clock input has internal termination resistors allowing it to interface with several differential signal types while minimizing the number of required external components. The device is packaged in a small, 3mm x 3mm VFQFN package, making it ideal for use on space-constrained boards.
