Clock Synthesizer
and Fanout Buffer/Divider
8T49NS010
DATA SHEET
General Description
The 8T49NS010 is a Clock Synthesizer and Fanout Buffer/Divider.
When used with an external crystal, the 8T49NS010 generates high
performance timing geared towards the communications and data-
com markets, especially for applications demanding extremely low
phase noise jitter, such as 10, 40 and 100GE.
The 8T49NS010 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 8T49NS010 supports two types of output levels. FORMAT #1
Outputs provide an output level with 750mV typical swing, and
requires external DC termination. FORMAT #2 Outputs provide a
similar swing level which does not require DC termination.
The device can be configured through an I2C serial interface and is
offered in a lead-free (RoHS6) 56-pin VFQFN package.
The extended temperature range supports telecommunication and
networking end equipment requirements.
Features
Ten differential outputs
The input operates in full differential mode (LVDS, LVPECL) or
single-ended LVCMOS mode
Can be driven from a crystal or differential clock
Support of output power-down
Excellent clock output phase noise
Offset Output Frequency Single-side Band Phase Noise
100kHz
156.25MHz
-144 dBc/Hz
Phase Noise RMS, 12kHz to 20MHz integration range:
