8V79S683 - JESD204B/C Compliant Fanout Buffer and Divider

Description

The 8V79S683 is a fully integrated, clock and SYSREF signal fanout buffer for JESD204B/C applications.

It is designed as a high-performance clock and converter synchronization solution for wireless base station radio equipment boards with JESD204B/C subclass 0, 1, and 2 compliance.

Features

  • Distribution, fanout, phase-delay of clock and SYSREF signals.
  • Very low output noise floor: -158.8dBc/Hz noise floor (245.76MHz).
  • Supports clock frequencies up to 3GHz, including clock output frequencies of 983.04MHz, 491.52MHz, 245.76MHz, and 122.88MHz.
  • Four output channels with a total of 16 differential outputs.
  • Each channel contains frequency dividers and clock phase delay circuits.
  • Phase alignment mode across multiple buffers with any frequency divider setting.

JESD204B/C Compliant Fanout Buffer and Divider 8V79S683 Datasheet Description The 8V79S683 is a fully integrated, clock and SYSREF signal fanout buffer for JESD204B/C applications. It is designed as a high-performance clock and converter synchronization solution for wireless base station radio equipment boards with JESD204B/C subclass 0, 1, and 2 compliance. The main function of the device is the distribution and fanout of high-frequency clocks and low-frequency system reference signals generated by a JESB204B clock generator such as the IDT 8V19N490, extending its fanout capabilities and providing additional phase-delay. The 8V79S683 is optimized to deliver very low phase noise clocks and precise, phase-adjustable SYSREF synchronization signals.
