The SiT95210 clock generator offers programmable quad fractional frequency translation-based jitter cleaning with flexible input to output frequency translation options. The ultra-high performance PLLs support up to 4 differential or 8 single-ended input clocks that are common for all 4 fractional translations and provide 4 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.
