Datasheet
General Description
The 853S011B is a low skew, high performance 1-to-2
Differential-to-2.5V/3.3V LVPECL/ECL Fanout Buffer. The
853S011B 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 853S011B ideal for those clock distribution
applications demanding well defined performance and repeatability.
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:
V_CC = 2.375V to 3.8V, V_EE = 0V
• ECL mode operating voltage supply range:
V_CC = 0V, V_EE = -3.8V to -2.375V
• -40°C to 85°C ambient operating temperature
• Available lead-free (RoHS 6) package
