BERTScope® Digital Pre-emphasis Processor and LE Linear Equalizer

Productivity and Insight for Serial Data Signaling

The BERTScope product family offers several Digital Signal Processing accessories to serve high speed serial designer needs in areas of Pre-Emphasis or Equalization.  

The Digital Pre-emphasis Processor DPP Series takes in single-ended inputs of data and clock and conditions the signal by adding precision amounts of pre-emphasis for use with Bit Error Rate Testers. Nine Tap Linear Equalization supporting speeds up to 32Gb/s is supported with the LE320 Series remote head, offering compact two channel precision equalization.

Features

Benefits

Range of operation 8Gb/s to 32Gb/sSupports emerging 100G, COMM standards and similar technologies operating with physical line rates up to 32Gb/s.
Standard 4 tap (optional 9 Tap) equalization+-20dB dynamic range on 4 standard taps and optional 9 taps filter designs supports a wide range design functions.
High Pass Filter designsRequired to model signal Pre-Emphasis or Continuous Time Linear Equalization operations.
Low Pass Filter designsSupport channel or backplane emulation.
General purpose signal amplificationApply 20dB low noise gain to any differential signal.
Channel or Backplane De-Embed operationsOpen eye and compensate for loss effects of long cables or interconnects.
0V-2.7V variable gain with return to zeroPrecision output level controls permit signaling from “0” (Return to Zero) to 2.7 V differentially.
Standalone operationOperated on a BERTScope or a user’s standalone PC supporting a wide set of operational models.
Fixed tap delay designEliminates external reference clock requirements.
Jitter pass throughAllows generator base sinusoidal, random jitter and bounded uncorrelated jitter components to pass from input to output un-impeded.
User configurable DDJThrough precision channel loss modeling, fine grain DDJ synthesis is offered to designers.
S-Parameter ImporterAllows users to define the LE320 channel response as an approximation of a user loaded touchstone file of a physical system.
