Data Sheet
General Description
The 8S89831I is a high speed 1-to-4 Differential- to-LVPECL/ECL
Fanout Buffer. The 8S89831I is optimized for high speed and very
low output skew, making it suitable for use in demanding applications
such as SONET, 1 Gigabit and 10 Gigabit Ethernet, and Fibre
Channel. The internally terminated differential input and VREF_AC pin
allow other differential signal families such as LVDS, LVHSTL and
CML to be easily interfaced to the input with minimal use of external
components. The device also has an output enable pin which may be
useful for system test and debug purposes. The 8S89831I is
packaged in a small 3mm x 3mm 16-pin VFQFN package which
makes it ideal for use in space-constrained applications.
Features
• Four LVPECL/ECL outputs
• IN, nIN input can accept the following differential input levels:
LVPECL, LVDS, CML, SSTL
• 50 internal input termination to VT
• Output frequency: >2.1GHz
• Output skew: 30ps (maximum)
• Part-to-part skew: 185ps (maximum)
• Additive phase jitter, RMS: 0.31ps (typical)
• Propagation Delay: 570ps (maximum)
• LVPECL mode operating voltage supply range:
VCC = 2.5V±5%, 3.3V±5%, VEE = 0V
• ECL mode operating voltage supply range:
VCC = 0V, VEE = -3.3V±5%, -2.5V±5%
• -40°C to 85°C ambient operating temperature
• Available in lead-free (RoHS 6) package
