Low phase noise, small chip size
~NPC releases LV-PECL output, SPXO module IC “7051 series”~

SEIKO NPC Corporation (HQ: Chuo-ku, Tokyo, President: Hiroaki Okawa) has released LV-PECL output , SPXO module IC “7051 series”.

Description

The “7051 series” is LV-PECL output SPXO module IC operable at 2.5V, supporting both fundamental oscillation (80MHz to 320MHz) and 3rd overtone oscillation (105MHz to 170MHz). The series is developed through BiCMOS process which enables the IC to be applied to various LV-PECL output terminal circuits.

Advantages

  • Low phase noise that realizes stable and high-grade communication (phase jitter reduced 70% compared with existing products)
  • Small chip size that allows crystal oscillator modules to be implemented into 3.2mm x 2.5mm package, improving flexibility of layout design
  • Operable up to 125℃, that expands your options much wider
