Renesas Electronics Corporation

Renesas’ Timing product portfolio has been acquired by SiTime.

Datasheets, documentation, and sample orders remain available on Renesas.com through late 2026. For new designs, purchasing, support, and product inquiries, visit SiTime.com or send an email to [email protected]. Full transition to SiTime is expected by late 2026.

Features

  • Two differential 2.5V, 3.3V LVPECL/ECL outputs
  • One differential PCLK, nPCLK input pair
  • PCLK, nPCLK pairs can accept the following differential input levels: LVPECL, LVDS, CML, SSTL
  • Maximum output frequency: >2.5GHz
  • Translates any single-ended input signal to 3.3V LVPECL levels with resistor bias on nPCLK input
  • Output skew: 5ps (typical)
  • Part-to-part skew: 130ps (maximum)
  • Propagation delay: 355ps (maximum)
  • LVPECL mode operating voltage supply range: VCC = 2.375V to 3.8V, VEE = 0V
  • ECL mode operating voltage supply range: VCC = 0V, VEE = -3.8V to -2.375V
  • -40°C to 85°C ambient operating temperature
  • Available lead-free (RoHS 6) package

Description

The 853S011BI is a low skew, high performance 1-to-2 Differential-to-2.5V/3.3V LVPECL/ECL Fanout Buffer. The 853S011BI is characterized to operate from either a 2.5V or a 3.3V power supply. Guaranteed output and part-to-part skew characteristics make the 853S011BI ideal for those clock distribution applications demanding well defined performance and repeatability.
