The ADCMP580/ADCMP581/ADCMP582 are ultrafast voltage comparators fabricated on the Analog Devices, Inc. proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. The ADCMP580 features CML output drivers, the ADCMP581 features reduced swing ECL (negative ECL) output drivers, and the ADCMP582 features reduced swing PECL (positive ECL) output drivers.

All three comparators offer 180 ps propagation delay and 100 ps minimum pulse width for 10 Gbps operation with 200 fs random jitter (RJ). Overdrive and slew rate dispersion are typically less than 15 ps.

The ±5 V power supplies enable a wide −2 V to +3 V input range with logic levels referenced to the CML/NECL/PECL outputs. The inputs have 50 Ω on-chip termination resistors with the optional capability to be left open (on an individual pin basis) for applications requiring high impedance input.

The CML output stage is designed to directly drive 400 mV into 50 Ω transmission lines terminated to ground. The NECL output stages are designed to directly drive 400 mV into 50 Ω terminated to −2 V. The PECL output stages are designed to directly drive 400 mV into 50 Ω terminated to V_CCO − 2 V. High speed latch and programmable hysteresis are also provided. The differential latch input controls are also 50 Ω terminated to an independent V_TT pin to interface to either CML or ECL or to PECL logic.

The ADCMP580/ADCMP581/ADCMP582 are available in a 16-lead LFCSP_VQ.

The model number is a specific version of a generic that can be purchased or sampled.

Status indicates the current lifecycle of the product. This can be one of 4 stages:

• Pre-Release: The model has not been released to general production, but samples may be available.
• Production: The model is currently being produced, and generally available for purchase and sampling.
• Last Time Buy: The model has been scheduled for obsolescence, but may still be purchased for a limited time.
• Obsolete: The specific part is obsolete and no longer available. Other models listed in the table may still be available (if they have a status that is not obsolete).

The package for this IC (i.e. DIP, SOIC, BGA). An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board.
