ADCMP580BCPZ-RL7

Overview

The ADCMP580BCPZ-RL7 is an ultrafast voltage comparator fabricated on Analog Devices' proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. It features CML output drivers designed to drive 400 mV into 50 Ω transmission lines terminated to ground. The device operates with ±5 V power supplies, enabling a wide −2 V to +3 V input range. Key performance metrics include a propagation delay of 180 ps, a minimum pulse width of 100 ps, and 200 fs random jitter, supporting 10 Gbps operation.

Feature Summary

• Ultrafast SiGe construction for high-speed signal processing
• CML output stage optimized for direct driving of 50 Ω grounded transmission lines
• Integrated differential latch control with internal termination
• Resistor-programmable hysteresis capability

Applications

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

Procurement Notes

Verify the specific suffix RL7 against the manufacturer's current ordering guide to confirm reel packaging specifications. Ensure the design utilizes the required ±5 V supply rails and proper 50 Ω transmission line terminations to achieve the specified electrical characteristics. Confirm that the LFCSP-16 package thermal requirements are met within the operating temperature range.

Selection Notes

Select this component when CML logic compatibility is required alongside ultrafast response times. The ADCMP580 differs from the ADCMP581 and ADCMP582 variants by its specific CML output driver configuration. Ensure the application can accommodate the necessary dual-supply architecture and that the input signals remain within the specified −2 V to +3 V common-mode range.

Part Context

This part belongs to the ADCMP580/ADCMP581/ADCMP582 family of comparators manufactured using the XFCB3 SiGe process. While all three share identical core comparator performance, the ADCMP580 is distinguished by its CML outputs, whereas the ADCMP581 provides NECL outputs and the ADCMP582 provides PECL outputs. All variants utilize a 16-lead LFCSP package.

Replacement Considerations

The ADCMP581BCPZ-RL7 and ADCMP582BCPZ-RL7 are confirmed substitutes within the same family, offering identical propagation delays but featuring NECL and PECL output stages respectively.
