PRECISION CLOCK GENERATOR

OC-192 APPLICATIONS

FEATURES:

DESCRIPTION:

• Input frequency:

The IDT5T940 generates a high precision FEC (Forward Error Cor-

rection) or non-FEC source clock for SONET/SDH systems as well as a

source clock for Gigabit Ethernet systems. This device also has clock

regeneration capability: it creates a "clean" version of the clock input by

using the internal oscillator to square the input clock's rising and falling

edges and remove jitter. In the event that the main clock input fails, the

device automatically locks to a backup reference clock using a hitless

switchover mechanism.

- ForSONETnon-FEC:19.44MHz,38.88MHz,77.76MHz,155.52MHz,

311.04MHz, or 622.08MHz

- For SONET FEC: 20.83MHz, 41.66MHz, 83.31MHz, 166.63MHz,

333.26MHz, or 666.52MHz

- For 10GE copper: 19.53MHz, 39.06MHz, 78.125MHz, 156.25MHz,

312.5MHz, or 625MHz

- For 10GE optical: 20.14MHz, 40.28MHz, 80.56MHz, 161.13MHz,

322.26MHz, or 644.53MHz

• 1x, 2x, 4x, 8x, 16x, and 32x outputs on Q^OUT

• Regenerated input clock or QOUT/4 on QREG

- Mode 1: QOUT range 622 - 666.5MHz. QREG output 155.5-166.6MHz.

- Mode 2: QOUT range 622 - 666.5MHz. QREG is a regenerated version

ofthe inputclockfrequency.
