ADCMP580BCP-WP

Overview

The ADCMP580BCP-WP is an ultrafast voltage comparator fabricated on Analog Devices' proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. It features CML output drivers, a propagation delay of 180 ps, and a minimum pulse width of 100 ps, supporting 10 Gbps operation with 200 fs random jitter. The device operates with ±5 V supplies, providing a −2 V to +3 V input range. It includes on-chip 50 Ω input terminations, resistor-programmable hysteresis, differential latch control, and power supply rejection exceeding 70 dB.

Feature Summary

• Ultrafast SiGe Voltage Comparator
• CML Output Drivers
• Differential Latch Control
• Resistor-Programmable Hysteresis

Applications

• Automatic test equipment (ATE)
• High speed instrumentation
• Medical imaging and diagnostics
• Clock and data signal restoration

Procurement Notes

Verify the specific ordering suffix WP against official documentation to confirm its exact meaning regarding temperature or reliability grade. Ensure the package type matches the required 16-lead LFCSP form factor. Confirm that the CML output interface aligns with system logic levels. Validate all electrical parameters against the latest Rev. B datasheet before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring high-speed threshold detection with low jitter. The CML output stage is designed to directly drive 400 mV into 50 Ω transmission lines terminated to ground. Consider the differential latch feature for capturing transient signals. Ensure proper bypassing of VCCI, VEE, and VCCO pins to maintain specified performance characteristics in high-frequency environments.

Part Context

This part belongs to the ADCMP580/ADCMP581/ADCMP582 family of ultrafast voltage comparators. While the ADCMP580 provides CML outputs, the ADCMP581 offers reduced swing ECL outputs, and the ADCMP582 provides reduced swing PECL outputs. All three share identical core performance metrics, including propagation delay and input range, differing primarily in their output driver configurations.

Replacement Considerations

Direct functional replacements within the same series include the ADCMP581 and ADCMP582, provided the system can accommodate NECL or PECL output logic levels respectively. Verify pin compatibility and termination requirements when substituting between these variants.
