The DS4125/DS4155/DS4156/DS4160/DS4311/DS4312/DS4622/DS4776 DS4-XO Series Crystal Oscillators are ceramic surface-mount crystal oscillators that are part of Maxim's DS4-XO series crystal oscillators family. These devices offer output frequencies at 125MHz, 155.52MHz, 156.25MHz, 160MHz, 311.04MHz, 312.5MHz, 622.08MHz, and 77.76MHz. The clock oscillators are suited for systems with tight tolerances because of the jitter, phase noise, and stability performance. The small package provides a format made for applications where PCB space is critical.
