ADCMP580BCP-RL7

Overview

The ADCMP580BCP-RL7 is an ultrafast voltage comparator fabricated on Analog Devices' proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. It features CML output drivers designed to directly drive 400 mV into 50 Ω transmission lines terminated to ground. The device offers a propagation delay of 180 ps and supports 10 Gbps operation with 200 fs random jitter. It operates with ±5 V power supplies, enabling a wide −2 V to +3 V input range. The component includes on-chip 50 Ω input termination resistors, resistor-programmable hysteresis, and differential latch control.

Feature Summary

• Ultrafast SiGe performance with 180 ps propagation delay for high-speed applications
• CML output stage optimized for direct driving of 50 Ω transmission lines
• Integrated 50 Ω input termination resistors with configurable open-pin capability
• Differential latch enable inputs with internal termination for signal acquisition

Applications

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

Procurement Notes

Verify the specific ordering suffix RL7 against the manufacturer's current documentation to confirm tape and reel packaging specifications. Ensure that the required supply voltages align with the ±5 V operational requirements detailed in the datasheet. Confirm that the LFCSP package dimensions match the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when CML logic compatibility is required for the output interface. Consider the ±5 V dual supply requirement during power budgeting. Evaluate the need for the integrated latch feature versus continuous comparison mode based on system timing requirements. Verify that the 180 ps propagation delay meets the specific bandwidth needs of the application.

Part Context

This part belongs to the ADCMP580/ADCMP581/ADCMP582 family of ultrafast voltage comparators. While the ADCMP581 provides NECL outputs and the ADCMP582 provides PECL outputs, the ADCMP580 specifically utilizes CML outputs. All variants share the same core SiGe architecture, pinout structure, and general electrical characteristics within the 16-lead LFCSP package.

Replacement Considerations

Direct functional substitutes within the same family include the ADCMP581BCP-RL7 and ADCMP582BCP-RL7. Note that these alternatives provide different output logic families (NECL and PECL respectively) compared to the CML outputs of the ADCMP580.
