Figure 1.
The ADCMP572/ADCMP573 are ultrafast comparators
fabricated on Analog Devices, Inc.’s proprietary XFCB3 Silicon
Germanium (SiGe) bipolar process. The ADCMP572 features
CML output drivers, and the ADCMP573 features reduced
swing PECL (RSPECL) output drivers.
Both devices offer 150 ps propagation delay and 100 ps
minimum pulse width for 10 Gbps operation with 200 fs RMS
random jitter (RJ). Overdrive and slew rate dispersion is
typically less than 15 ps.
A flexible power supply scheme allows either device to operate
with a single +3.3 V positive supply and a 0.2 V to +1.2 V
input signal range, or with split input/output supplies to
support a wider 0.2 V to +3.2 V input signal range and an
independent range of output levels. 50 on-chip termination
resistors are provided at both inputs with the optional capability
to leave open (on an individual pin basis) for applications
requiring high impedance inputs.
The CML output stage is designed to directly drive 400 mV into
50 transmission lines terminated to between 3.3 V to 5.2 V.
The RSPECL output stage is designed to drive 400 mV into
50 terminated to V
CCO
2 V and is compatible with several
commonly used PECL logic families. 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. High speed latch and programmable
hysteresis features are also provided.
The ADCMP572/ADCMP573 are available in a 16-lead LFCSP
package.
