SiT95314
Quad PLL, 4-output Jitter Cleaner
The SiT95314 jitter cleaner offers programmable quad fractional frequency translation based jitter cleaning with flexible input to output frequency translation options. The high performance PLLs support up to 4 differential or 8 single-ended input clocks 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.
