SiT95316数据手册SiTime中文资料规格书

描述 Description

The SiT95316 network synchronizer offers programmable quad fractional frequency translation with flexible input to output frequency translation options. The high performance DPLLs support up to 4 differential or 8 single-ended input clocks and provide 12 clock outputs. The clock outputs can be derived from any of the 4 PLLs in a fully flexible manner. This device is fully programmable with the I2C/SPI interface or an on-chip one time programmable (OTP) non-volatile memory for factory pre-programmed devices.
