1 / 57 page 1 ©2016 Integrated Device Technology, Inc. September 2, 2016 General Description The 8V49NS0312 is a Clock Generator with four output dividers: three integer and one that is either integer or fractional. When used with an external crystal, the 8V49NS0312 generates high perfor- mance timing geared towards the communications and datacom markets, especially for applications demanding extremely low phase noise, such as 10, 40 and 100GE. The 8V49NS0312 provides versatile frequency configurations and output formats and is optimized to deliver excellent phase noise performance. The device delivers an optimum combination of high clock frequency and low phase noise performance, combined with high power supply noise rejection. The 8V49NS0312 supports two types of output levels: LVPECL or LVDS on eleven of its outputs. In addition there is a single LVCMOS output that has the option of providing a generated clock or acting as a reference bypass output. The device can be configured to deliver specific output configurations under pin control only or additional configurations through an I2C serial interface. It is offered in a lead-free (RoHS6) 64-pin VFQFN package. Features ▪ Eleven differential LVPECL, LVDS outputs with programmable voltage swings ▪ One LVCMOS output — Input reference maybe bypassed to this output ▪ The clock input operates in full differential mode (LVDS, LVPECL) or single-ended LVCMOS mode ▪ Driven from a crystal or differential clock input ▪ 2.4-2.5GHz PLL frequency range supports Ethernet, SONET and CPRI frequency plans ▪ Four Integer output dividers with a range of output divide ratios (see Table 7) ▪ One Fractional Output divider can generate any desired output frequency ▪ Support of output power-down ▪ Excellent clock output phase noise Offset Output Frequency Single-side Band Phase Noise 100kHz 156.25MHz -143dBc/Hz ▪ Phase Noise RMS, 156.25MHz, 12kHz to 20MHz integration range: 110fs (maximum) ▪ Select configurations may be controlled via the use of control input pins without need for serial port access ▪ LVCMOS compatible I2C serial interface gives access to additional configurations either alone or in combination with the control input pins ▪ Single 3.3V supply voltage ▪ Lead-free (RoHS 6) 64-pin VFQFN packaging ▪ -40°C to 85°C ambient operating temperature FemtoClock® NG Clock Generator with 4 Dividers 8V49NS0312 Datasheet |
