The delay generation principle relies on the linear charge of a capacitor triggered by the input pulse. The output pulse generation occurs when the capacitor voltage exceeds a threshold voltage. The delay full scale is automatically set to match the period of the master clock, ranging from 5-7 ns, with the help of an embedded calibration circuit. The delay value is controlled with the help of a 14-bit DAC setting the threshold voltage, which leads to a 400 fs delay step. Among other features, the chip embeds a combination mode of either 2 or 4 channels to output narrow width pulses. The chip is fully compliant with LVDS, LVPECL and CML differential input pulses and outputs LVPECL pulses. The chip has been fully characterized over temperature (0 to 60 °C) and supply voltage (± 10%). The chip is compliant with pulse repetition frequencies up to 20 MHz. The measured INL is 100 LSB and the RMS jitter is 1.8 ps. The power consumption has been measured to 350 mW for 4 active channels.
