8T49N028 Datasheet Multiple Frequency Clock Generator

Manufacturer: Integrated Device Technology

Overview: FemtoClock® NG Crystal-to-3.3V, 2.5V Multiple Frequency Clock Generator w/Fanout Buffer 8T49N028 DATA SHEET.

General Description

The 8T49N028 is a low RMS phase jitter Clock Synthesizer with selectable internal crystal oscillator or external clock references and eight outputs, configurable as either LVDS, LVPECL or High Impedance.

After power up, two frequency select pins determine one of up to four different sets of factory preprogrammed crystal or input frequency and output frequency configurations.

From a single input reference, as many as three different output frequencies may be selected for the output banks: two of these frequencies can be generated by the internal crystal oscillator, and/or external clock pre-divider, and/or A output divider, and/or B output divider.

Key Features

  • Fourth Generation FemtoClock NG PLL technology.
  • Eight selectable LVPECL or LVDS outputs (bank selectable, two output channels per bank).
  • CLK, nCLK input pair can accept the following differential input levels: LVPECL, LVDS, HCSL.
  • FemtoClock NG VCO Range: 1.92GHz - 2.5GHz.
  • Bank A and B output frequencies are mux selectable from internal crystal oscillator, reference clock input, output divider A or output divider B.
  • Clock from OUTPUT.
