Status: In Production
The SM843256 provides a low-noise timing solution for high speed, high accuracy synthesis of clock signals. Common applications include SONET, Gigabit Ethernet, 10 Gigabit Ethernet, and similar networking standards.Power supplies of either 3.3V or 2.5V are supported, with superior jitter and phase noise performance. The device synthesizes different low noise LVPECL output frequencies such as 125MHz, 156.25MHz, 312.5MHz, and 625MHz for Ethernet applications; 77.76MHz, 155.52MHz, 311.04MHz, and 622.08MHz for SONET applications. The crystal reference frequencies used include 25MHz and 19.44Mhz for Ethernet and SONET applications, respectively.The SM843256 is an excellent replacement for IDT Femto-clocks, with improved accuracy, power consumption, waveform integrity, and jitter.
