PECL Clock Synthesizer, 3.3 V / 5 V, 50 - 200 MHz

Active

Overview

The NB4N507A is a precision clock synthesizer which generates a very low jitter differential PECL output clock. It produces a clock output based on an integer multiple of an input reference frequency.
The NB4N507A accepts a standard fundamental mode crystal, using Phase-Locked-Loop (PLL) techniques, will produce output clocks up to 200 MHz. In addition, the PLL circuitry will produce a 50% duty cycle square-wave clock output.
The NB4N507A can be programmed to generate a selection of input reference frequency multiples. An exact 155.52 MHz output clock can be generated from a 19.44 MHz crystal and the x8 multiplier selection. The NB4N507A is intended for low output jitter clock generation.

  • PECL clock generation in networking, communications and computing.
  • Crystal oscillator replacement.
  • General purpose PECL clock gneration.

  • Input Crystal Frequency of 10 - 27 MHz
  • Enable Usage of Common Low-Cost Crystal
  • Differential PECL Output Clock Frequencies up to 200 MHz
  • Duty Cycle of 48%/52%
  • Operating Range: VCC = 3.0 V to 5.5 V
  • Ideal for SONET Applications and Oscillator Manufacturers
  • Available in Die Form
  • Pb-Free Packages are Available
