Product details
Overview
ADCMP580BCPZ-RL7 from Analog Devices is an ultrafast SiGe voltage comparator with CML output drivers, designed for 10 Gbps signal restoration and threshold detection in high-speed test and instrumentation systems. It delivers 180 ps propagation delay, 37 ps output rise/fall time, 8 GHz equivalent input bandwidth, and operates across −40°C to +125°C with ±5 V supplies and −2 V to +3 V input range.
For engineers reviewing the ADCMP580BCPZ-RL7 datasheet, ADCMP580BCPZ-RL7 pinout, ADCMP580BCPZ-RL7 application, or ADCMP580BCPZ-RL7 equivalent, this page provides verified technical context, real-world timing behavior, CML interface constraints, latch control timing margins, and validated alternatives for ATE, pulse spectroscopy, and clock/data recovery designs.
Technical Context
The ADCMP580BCPZ-RL7 implements a differential SiGe comparator core with on-chip 50 Ω input terminations at VP and VN, each with dedicated return pins (VTP/VTN), enabling flexible single-ended or differential input configurations without external resistors. Its CML output stage drives 400 mV into 50 Ω to ground, with matched rise/fall times and deterministic jitter of 15 ps at 5 Gbps.
It features dual differential latch enable inputs (LE/LE) terminated to VTT (ground for ADCMP580), supporting compare/latch modes with 95 ps setup time and −90 ps hold time. Hysteresis is resistor-programmable via the HYS pin tied to VEE, and power supply rejection exceeds 70 dB on both VCCI and VEE rails.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADCMP572BCPZ-R7 | Slower 450 ps propagation delay; LVDS outputs; no on-chip input termination | Targeted at <500 Mbps industrial interfaces, not 10 Gbps ATE or spectroscopy | Select when lower speed, lower power, and LVDS compatibility outweigh timing performance needs |
| TLV3501CDR | CMOS output; 4.5 ns propagation delay; 200 MHz bandwidth; 3.3 V supply only | Suitable for general-purpose high-speed comparators in consumer electronics, not RF/test gear | Choose for cost-sensitive, non-critical timing applications where jitter and bandwidth are less constrained |

FAQ
What is the recommended termination for ADCMP580BCPZ-RL7 CML outputs?
The ADCMP580BCPZ-RL7 CML outputs must be terminated to ground through 50 Ω resistors per output. The device's CML stage is designed to deliver 400 mV differential swing into 50 Ω to GND, and mismatched termination causes reflection-induced pulse width dispersion and increased deterministic jitter. VTT must also be connected to GND to properly bias the latch enable inputs.
Does ADCMP580BCPZ-RL7 support single-ended input operation?
Yes, ADCMP580BCPZ-RL7 supports single-ended inputs by terminating one input (e.g., VN) to a fixed reference voltage via its dedicated VTN pin, while applying the signal to VP. The on-chip 50 Ω termination at VP remains active, and VTP must be connected to the same reference. This configuration preserves 180 ps propagation delay and maintains input common-mode range compliance.
How is hysteresis programmed on ADCMP580BCPZ-RL7?
Hysteresis on ADCMP580BCPZ-RL7 is programmed by connecting the HYS pin to VEE (−5 V) through an external resistor. A 1 kΩ resistor yields ~70 mV hysteresis; values up to 5 kΩ reduce hysteresis to ~1 mV. Leaving HYS open results in zero hysteresis. The relationship between RHYS and hysteresis voltage is monotonic and documented in Figure 8 of the Rev. B datasheet.
What is the function of the VTP and VTN pins on ADCMP580BCPZ-RL7?
VTP and VTN are dedicated termination return pins for the on-chip 50 Ω resistors at VP and VN, respectively. They allow independent routing of termination references-critical for minimizing ground bounce and maintaining input balance in high-speed layouts. Unlike conventional comparators, ADCMP580BCPZ-RL7 does not share a common termination node, enabling optimized PCB stackup for differential signaling.
Can ADCMP580BCPZ-RL7 operate with only +5 V and GND supplies?
No. ADCMP580BCPZ-RL7 requires dual ±5 V supplies (VCCI = +5 V, VEE = −5 V) to achieve its specified −2 V to +3 V input range and CML output swing. Operating with only +5 V and GND violates absolute maximum ratings, disables internal biasing, and prevents proper latch enable functionality-resulting in undefined output states and potential damage.
