FemtoClock^®NG Ultra Low Jitter

HCSL Clock Generator

8V41NS0412

Datasheet

Description

Features

▪ Eleven differential HCSL outputs

The 8V41NS0412 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 8V41NS0412 generates high

performance timing geared towards the communications and

datacom markets, especially for applications demanding

extremely low phase noise, such as 10GE, 40GE, 100G, and

400GE.

▪ One LVCMOS output; input reference can be 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

▪ A 2.42.5GHz PLL frequency range supports Ethernet,

The 8V41NS0412’s versatile frequency configurations are

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.

SONET, and CPRI frequency plans

▪ 1.25GHz maximum output frequency

▪ Four integer output dividers with a range of output divide ratios

(see Table 5)

▪ One fractional output divider can generate any desired output

frequency

The 8V41NS0412 supports HCSL type of output level 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.

▪ Support of output power-down

▪ Excellent clock output phase noise

Offset Output Frequency Single-side Band Phase Noise

The device can be configured to deliver specific configurations

under pin control only, or additional configurations through an I²C

serial interface by an external processor.

100kHz

156.25MHz

-143dBc/Hz

▪ Phase noise RMS, 156.25MHz, 12kHz to 20MHz integration

range: 80fs (typical)

The 8V41NS0412 is offered in a lead-free (RoHS6) 64-VFQFN

package.

▪ Selected configurations can 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 by external processor or in

combination with the control input pins

Typical Applications

▪ PCI Express Clocking

▪ Single 3.3V supply voltage

▪ 10G/40G/100G/400G Ethernet

▪ Gb Ethernet, Terabit IP switches / routers

▪ CPRI Interfaces

▪ Lead-free (RoHS 6) 64-VFQFN packaging

▪ -40°C to 85°C ambient operating temperature

▪ Fiber Optics
