BERT428 is 100Gb/s BERT. EPG428 is an Electrical Pattern Generator module that plugs into the PARALLEX? Chassis. EPG428 can generate 4 channel electrical data from 1 Gb/s up to 29 Gb/s continuously. EED428 is an Electrical Error Detector module that plugs into the PARALLEX? Chassis. EED428 can check 4 channels electrical data from 22.0 - 28.2Gbps and 8.5Gb/s – 14.1Gb/s.

EPG428 Key Spec

Note:

1. Output of clock signal is used for daisy chaining additional modules. Maximum daisy chain length is four.
2. RJ measured with CLK pattern. Depends on applied clock signal (measured with CLK20-2 Module, RJ=200fs)
3. Measured at 1GBd at the static High/ Low level of the signal with de-emphasis=0dB.
   The eye height at higher data rates might differ.

EED428 Key Spec

Note:

1. Apply full rate clock for low data rate range and half rate clock for high data rate range.
2. Additional DR/40 CLK output installed
3. BER of better than 1E-12 can only be achieved if at least the min. input voltage level is applied
4. Minimum input voltage to guarantee error free detection (BER < 10-12) at PRBS31. The input sensitivity of??????????
   the module will be better for input signals with lower bandwidth, e.g. PRBS7.
