Multiplier
Data Sheet
Preliminary Version 0.91
Accurate and simplified receiver test for PCI Express ®,
SD UHS-II host and MIPI M-PHY devices:
Multiplies 19.2 to 100 MHz reference clocks to an external clock
signal for J-BERT or ParBERT pattern generators
Transparent to 33 kHz SSC on the reference clock because N4880A
uses a multiplying PLL with 2 or 5 MHz loop bandwidth
Tolerates small input signals with an input sensitivity of 100 mVpp
differential
Stand-alone graphical user interface and remote control interface via
rear panel USB 2.0 connection

Target Bit Rate (1)
7G versions of J-BERT N4903B and ParBERT 81250 can be used, even if N4880A output clock rate is higher than 7 GHz.
case of a reference clock between 26 MHz and < 28.125 MHz and the need for sinusoidal jitter injection a N4916B-001 clock
doubler has to be applied between the reference clock multiplier output and the J-BERT external clock input. In addition, the
pattern generator bits need to be doubled (e.g. 01 -> 0011) to compensate for the clock doubling.
