2:1 Differential-to-LVPECL Multiplexer
Datasheet
853S01
General Description
The 853S01 is a high performance 2:1 Differential-to-LVPECL
Multiplexer. The 853S01 can also perform differential translation
because the differential inputs accept LVPECL, LVDS and CML
levels. The 853S01 is packaged in a small 3mm x 3mm 16 VFQFN
package, making it ideal for use on space constrained boards.

One LVPECL output pair
Two selectable differential LVPECL clock inputs
PCLKx, nPCLKx pairs can accept the following
differential input levels: LVPECL, LVDS, CML
Translates LVCMOS/LVTTL input signals to LVPECL levels by
using a resistor bias network on nPCLKx, nPCLKx
Part-to-part skew: 150ps (maximum)
Propagation delay: 490ps (maximum)
Full 3.3V or 2.5V operating supply
-40°C to 85°C ambient operating temperature
Available in lead-free (RoHS 6) packages

Absolute Maximum Ratings
NOTE: Stresses beyond those listed under
Absolute Maximum Ratings
may cause permanent damage to the device.
These ratings are stress specifications only. Functional operation of product at these conditions or any conditions beyond
those listed in the
DC Characteristics or AC Characteristics
is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect product reliability.

NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the device is
mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after thermal equilibrium
has been reached under these conditions.
NOTE: All parameters measured at ƒ
1.0GHz unless otherwise noted.
NOTE 1: Measured from the differential input crossing point to the differential output crossing point.
NOTE 2: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 3: Defined as skew between outputs on different devices operating at the same supply voltage, same temperature, same frequency and
with equal load conditions at the same temperature. Using the same type of inputs on each device, the outputs are measured at the differential
cross points.
NOTE 4: Driving only one input clock.
NOTE 5: Q, nQ output measured differentially. See
