I2C Programmable Ethernet Clock Generator
8T49N4811
DATA SHEET
General Description
The 8T49N4811I is a highly flexible FemtoClock® NG pin-programmable clock generator suitable for networking and communications applications. It is able to generate five different output frequencies with multiple copies of each. A fundamental mode crystal, single-ended, or differential input reference may be used as the source for the output frequency.
The use of pin-programming to select the input source / frequency, desired output frequencies and output styles allow a single device to be used in a wide variety of applications without the need for register programming.
Selection pins use 3-level options to maximize flexibility while minimizing package size.
