The DS4125–DS4776 DS4-XO series crystal oscillators are from Maxim company, offer frequencies at 125MHz, 155.52MHz, 156.25MHz, 160MHz, 311.04MHz, 312.5MHz, 622.08MHz and 77.76MHz, and have very low jitter and phase noise. They are suitable for systems with tight tolerances. The package size is 5.0mm x 3.2mm x 1.49mm and the package type is 10-pin LCCC surface mount ceramic.
The DS4‑XO series from Maxim includes ceramic surface‑mount crystal oscillators (DS4125‑DS4776) that provide selectable output frequencies such as 125 MHz, 155.52 MHz, 156.25 MHz, 160 MHz, 311.04 MHz, 312.5 MHz, 622.08 MHz and 77.76 MHz. They are crystal‑based with PLL synthesis, support LVDS or LVPECL differential outputs, and feature an active‑high output‑enable pin.
Key specifications include a typical phase jitter of < 0.7 ps RMS, operating voltage 3.3 V ± 5 %, temperature range –40 °C to +85 °C, and a 5.0 mm × 3.2 mm × 1.49 mm 10‑pin LCCC ceramic package. The document provides detailed electrical characteristics, pin descriptions, ordering information and mechanical drawings.
