PrA | Page 6 of 35 BIT ERROR RATE MONITOR (BERMON) SPECIFICATIONS TA = TMIN to TMAX, VCC = VMIN to VMAX, VEE = 0 V, CF = 0.47 uF, SLICEP = SLICEN = VEE, Input Data Pattern: PRBS 223 − 1, unless otherwise noted. Table 4. Parameter Conditions Min Typ Max Unit BERMON Primary Mode I2C Controlled Eye Profiling BER Accuracy Input BER Range 1e-3 to 1e-12, Input DJ<0.4UI, DJ Ceiling>1e-2. Asymmetry <0.1UI. Requires external data processing algorithms to implement Q factor extrapolation. +/-1 Decades Numbits Number of data bits to collect pseudo-errors. User programmable in increment factors of 23 over the range 218 to 239. 218 239 UI Measurement Time Numbits/Datarate s Sample Phase Adjust Resolution 6 degrees BER Range 5e-2 BER Power Increase BER On 177 mW BER Standby 88 mW BERMON Secondary Mode Analog Voltage Output BER Accuracy Input BER Range 1e-3 to 1e-9, Input DJ=0 UI, DJ Ceiling>1e-2. Asymmetry =0 UI. BER is read as a voltage on pin VBER, when Automode = 0. +/-1 Decades BER Accuracy Input BER Range 1e-3 to 1e-9, Input DJ=0.2 UI, DJ Ceiling>1e-2. Asymmetry =0 UI.
