Micrel DSC2044
The DSC2044 series of high performance dual output oscillators utilize a proven silicon MEMS technology to provide excellent jitter and stability while incorporating additional device functionality. The two outputs are controlled by separate supply voltages to allow for high output isolation. The frequencies of the outputs can be identical or independently derived from a common PLL frequency source.| Part No. | DSC2044 |
