The SiT9505 is a differential oscillator with an integrated MEMS resonator, engineered for low-jitter applications requiring one of the following standard frequencies: 100 MHz, 156.25 MHz, 312.5 MHz, or 625 MHz. A unique FlexSwing™ output-driver performs like LVPECL and provides independent control of voltage swing and DC offset to simplify interfacing with chipsets having non-standard 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.
The SiT9505 can be factory programmed for specific combinations of frequency, stability, output signaling, voltage, and output enable functionality. The wide frequency range and programmability makes this device ideal for communications, enterprise, and industrial applications that require a variety of frequencies and operate in noisy environments.
