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.
