Differential-to-LVDS Buffer/Divider
with Internal Termination
IDT8S89872I
Datasheet
Description
The IDT8S89872I is a high speed Differential-to-LVDS Buffer/Divider
with Internal Termination. The IDT8S89872I has a selectable ÷2, ÷4,
÷8, ÷16 output dividers. The clock input has internal termination
resistors allowing it to interface with several differential signal types
while minimizing the number of required external components.
The nRESET/nDISABLE asynchronously resets the QB output bank.
QA outputs are synchronously enabled or disabled on the next falling
edge of IN, or rising edge of nIN. Please refer to the timing diagram
for details.
The device is packaged in a small, 3 x 3 mm VFQFN package,
making it ideal for use on space-constrained boards.
Features
Three LVDS outputs
Frequency divide select options: ÷2, ÷4, ÷8, ÷16
IN, nIN input can accept the following differential input levels:
LVPECL, LVDS, CML
Output frequency: 2GHz
Additive phase jitter: 0.15ps (typical)
Output skew: 30ps (maximum), QBx, nQBx outputs
Part-to-part skew: 250ps (maximum)
Propagation Delay: 530ps (typical)
Full 2.5V supply mode
-40°C to 85°C ambient operating temperature
Available in lead-free (RoHS 6) package
