8T49N1012中文资料FemtoClock® NG 12-Output Frequency Synthesizer数据手册Renesas规格书

描述 Description

The 8T49N1012 has one fractional-feedback PLL that can be used for frequency synthesis. It is equipped with two integer and eight fractional output dividers, allowing the generation of up to ten different output frequencies, ranging from 8kHz to 1GHz. Eight of these frequencies are completely independent of each other and the inputs. Two more are related frequencies. The twelve outputs may select among LVPECL, LVDS, HSCL or LVCMOS output levels.

This functionality makes it ideal to be used in any frequency synthesis application, including 1G, 10G, 40G and 100G Synchronous Ethernet, OTN, and SONET/SDH, including ITU-T G.709 (2009) FEC rates. The device supports Output Enable inputs and Lock and LOS status outputs.

特性 Features

• 0.3 ps RMS typical jitter (including spurs), 12 kHz to 20 MHz
• Operating modes: locked to input signal and free-run
• Digitally Controlled Oscillator (DCO) mode for software adjustment of operating frequency
