8S89874I中文资料1:2 Differential-to-LVPECL Buffer/Divider数据手册Renesas规格书

描述 Description

The 8S89874I is a high speed 1:2 Differential-to- LVPECL Buffer/ Divider. The 8S89874I has a selectable ÷1, ÷2, ÷4, ÷8, ÷16 output divider, which allows the device to be used as either a 1:2 fanout buffer or frequency divider. 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.
