Overview
The ADCMP573BCP-RL7 is an ultrafast comparator fabricated on Analog Devices' proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. It features reduced swing PECL (RSPECL) output drivers and latch inputs, offering a propagation delay of 150 ps and a minimum pulse width of 80 ps for 10 Gbps operation. The device operates with a single 3.3 V or 5.2 V positive supply, providing flexible power schemes including split input/output supplies. It includes on-chip 50 Ω input terminations, robust input protection against phase reversal, resistor-programmable hysteresis, and differential latch control.
Feature Summary
- Features RSPECL output drivers compatible with common PECL logic families
- Includes differential latch control for high-speed signal capture
- Provides resistor-programmable hysteresis for noise immunity
- Offers robust input protection preventing output phase reversal
Applications
- Clock and data signal restoration and level shifting
- Automatic test equipment (ATE)
- High speed instrumentation
- Medical imaging and diagnostics
- Threshold detection and peak detectors
Procurement Notes
Verify the specific ordering suffix to confirm the reel packaging configuration required for automated assembly processes. Confirm that the RSPECL output voltage levels align with the receiving logic family termination requirements. Ensure the design accounts for the extended industrial temperature range specifications during procurement planning.
Selection Notes
Select this component when RSPECL signaling compatibility is required rather than standard CML outputs. Consider the device for applications needing precise latch timing control and low jitter performance. Evaluate the power supply flexibility to determine if split supply operation is necessary for the specific input signal range.
Part Context
This part belongs to the ADCMP572/ADCMP573 series of ultrafast comparators manufactured by Analog Devices Inc. The series utilizes SiGe technology to achieve high bandwidth and low jitter characteristics suitable for gigabit-per-second data rates.
Replacement Considerations
The ADCMP572BCPZ-RL7 serves as a functional alternative within the same series, differing primarily in its CML output driver configuration instead of the RSPECL outputs found in the ADCMP573 variant.
FAQ
How is the latch feature disabled on the ADCMP573?
To disable the latch feature, connect the LE pin to VCCO with an external 500 Ω resistor and leave the LE pin disconnected.
What is the typical random jitter specification for this device?
The device exhibits a root mean square (RMS) random jitter of 200 fs under specified operating conditions.
