The SiT95211 offers programmable quad fractional frequency generation and translation with flexible input to output frequency translation options. Ultra high jitter performance DPLL supports up to 4 differential or single-ended input clocks that are common for all the 4 fractional PLLs and provides 12 differential output clocks. 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 non-volatile memory for factory pre-programmed devices.
