The DS4106, DS4212, and DS4425 ceramic surface-mount crystal oscillators are part of Maxim’s DS4-XO series of crystal oscillators. These devices offer output frequencies at 106.25MHz, 212.5MHz, and 425MHz. 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. These clock oscillators are crystal based and use a fundamental crystal with PLL technology to provide the final output frequencies. Each device is offered with LVDS or LVPECL output types. The output enable pin is active-high logic. These clock oscillators have very low phase jitter and phase noise. Typical phase jitter is < 0.9ps RMS from 12kHz to 20MHz. The devices are designed to operate with a 3.3V ±10% supply voltage, and are available in a 5.0mm x 3.2mm x 1.49mm, 10-pin LCCC surface-mount ceramic package.
The Maxim DS4106, DS4212 and DS4425 are ceramic surface‑mount crystal oscillators that provide precise clock outputs of 106.25 MHz, 212.5 MHz and 425 MHz. They use a crystal with PLL technology and are offered with either LVPECL or LVDS output buffers.
The devices operate from a 3.3 V ±10 % supply (3.0 V to 3.6 V), draw typical currents of 50 mA (LVPECL) or 53 mA (LVDS), and are specified for a temperature range of –40 °C to +85 °C. They are packaged in a 5.0 mm × 3.2 mm × 1.49 mm 10‑pin LCCC ceramic package.
