SM802141 Overview
Description
The SM802141 is a part of Micrel’s ClockWorks family of devices and provides an extremely low-noise timing solution for Ethernet clock signals. The device operates from a 3.3V or 2.5V power supply and synthesizes differential LVPECL output clocks at 62.5MHz, 125MHz, 156.25MHz or 312.5MHz, selectable through logic control pins.
Key Features
- Configurable to generate up to four different LVPECL clock frequencies
- 2.5V or 3.3V operating range
- Typical phase jitter @ 125MHz (12kHz to 20MHz): 255 fsrms
- Industrial temperature range (–40°C to +85°C)
- Green, RoHS, and PFOS compliant
