The ADCMP572BCPZ-WP is an ultrafast single-supply SiGe Comparator fabricated on proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. The ADCMP572 features CML output drivers and latch inputs. The device offers 150ps propagation delay and 80ps minimum pulse width for 10Gbps operation with 200fsrms random jitter (RJ). Overdrive and slew rate dispersion are typically less than 15ps. A flexible power supply scheme allows both devices to operate with a single 3.3V positive supply and a -0.2 to 1.2V input signal range or with split input/output supplies to support a wider -0.2 to 3.2V input signal range and an independent range of output levels. 50R on-chip termination resistors are provided at both inputs with the optional capability to be left open for applications requiring high impedance inputs. The comparator input stage offers robust protection against large input overdrive and the outputs do not phase reverse when the valid input signal range is exceeded.
