The DSC2044FI2-F0022 is a programmable, high performance dual HCSL output oscillator utilizing Microchip's proven silicon MEMS technology to provide excellent jitter and stability while incorporating additional device functionality. Two HCSL outputs are controlled by separate supply voltages to allow for high output isolation. The frequencies of the outrputs can be identical or independently derived from a common PLL frequency source. The DSC2044FI2-F0022 has provision for up to eight user-defined pre-programmed, pin-selectable output frequency combinations.
