SiT9501 PRELIMINARY Ultra-low Jitter Differential XO for Standard Networking Frequencies Description The SiT9501 is a differential MEMS oscillator that is engineered for low-jitter applications requiring standard frequencies from 25 MHz to 644.53125 MHz. In addition to standard differential signaling types, a unique FlexSwing™ output-driver performs like LVPECL and provides independent control of voltage swing and DC offset to simplify interfacing with chipsets having nonstandard input voltage requirements and eliminate all external source-bias resistors. The device also integrates multiple on-chip regulators to filter power supply noise, eliminating the need for an external dedicated LDO.
