Programmable FemtoClock^®NG LVPECL/LVDS

Clock Generator with 8-Outputs

IDT8T49N008I

DATASHEET

General Description

Features

The IDT8T49N008I is an eight output Clock Synthesizer with

selectable LVDS or LVPECL outputs. The IDT8T49N008I can

synthesize any one of four frequencies from a single crystal or

reference clock. The four frequencies are selected from the

Frequency Selection Table (Table 3A) and are programmed via I²C

interface. The four predefined frequencies are selected in the user

application by two frequency selection pins. Note the desired

programmed frequencies must be used with the corresponding

crystal or clock frequency as indicated in Table 3A.

• Fourth Generation FemtoClock NG PLL technology

• Eight selectable LVPECL or LVDS outputs

• CLK, nCLK input pair can accept the following differential input

levels: LVPECL, LVDS, HCSL

• FemtoClock NG VCO Range: 1.91GHz - 2.5GHz

• RMS phase jitter at 156.25MHz (12kHz - 20MHz):

228fs (typical)

• RMS phase jitter at 156.25MHz (10kHz - 1MHz): 175fs (typical)

• Full 2.5V or 3.3V power supply

Excellent phase noise performance is maintained with IDT’s Fourth

Generation FemtoClock^®NG PLL technology, which delivers

sub-400fs RMS phase jitter.

• I²C programming interface

• PCI Express (2.5 Gb/S), Gen 2 (5 Gb/s) and Gen 3 (8 Gb/s) jitter

compliant

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

• Lead-free (RoHS 6) packaging
