MAX3610
Low-Jitter 106.25MHz/212.5MHz Fibre-Channel Clock Generator
|
Overview
The MAX3610 is a low-jitter, high-performance, dual-rate clock generator optimized for 1Gbps/2Gbps/4Gbps Fibre-Channel applications. When connected with an external AT-cut crystal, the device generates a precision clock output by integrating a crystal oscillator with a low-noise phase-locked loop (PLL) providing a low-cost solution. By coupling a low-noise PLL design featuring a low-jitter generation VCO with an inexpensive fundamental mode crystal, the MAX3610 provides the optimum combination of low cost, flexibility, and high performance. The MAX3610 output frequency is selectable. When using a 26.5625MHz crystal, the output clock rate can be set to either 106.25MHz or 212.5MHz. When operating at 106.25MHz, the typical phase jitter is 0.7psRMS from 12kHz to 20MHz. The MAX3610A has low-voltage positive-emitter-coupled logic (LVPECL) clock output drivers. The MAX3610B has low-voltage differential-signal (LVDS) clock output drivers. The MAX3610 output drivers can also be disabled. The MAX3610 operates from a single +3.3V supply. The PECL version typically consumes 165mW, while the LVDS version typically consumes 174mW. Both devices are available in die form and have a 0°C to +85°C operating temperature range. |
