Product details
Overview
ADCMP580BCPZ-WP 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 digital systems. It delivers 180 ps propagation delay, 37 ps output rise/fall time, and 200 fs random jitter, operating from ±5 V supplies with −2 V to +3 V input range. Used in automatic test equipment and medical imaging front-ends.
For engineers reviewing the ADCMP580BCPZ-WP datasheet, ADCMP580BCPZ-WP pinout, ADCMP580BCPZ-WP application, or ADCMP580BCPZ-WP equivalent, key selection factors include CML output compatibility with 50 Ω ground-terminated lines, differential latch control timing (95 ps setup), resistor-programmable hysteresis, and −40°C to +125°C operation in a 16-lead LFCSP package.
Technical Context
The ADCMP580BCPZ-WP implements a fully differential SiGe comparator core with on-chip 50 Ω input terminations at both VP and VN pins, referenced to VTP and VTN. Its CML output stage drives 400 mV into 50 Ω to ground, eliminating external termination components.
It features dual differential latch enable inputs (LE/LE) with 50 Ω on-chip termination to VTT (ground for ADCMP580), supporting precise edge-triggered sampling. Hysteresis is controlled via the HYS pin connected to VEE through an external resistor, enabling adjustable noise immunity without altering signal path integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 180 ps - enables sub-100 ps timing resolution in 10 Gbps data recovery paths |
| Input Voltage Range | −2 V to +3 V - supports wide common-mode swing with ±5 V supplies |
| Output Type | CML - directly drives 50 Ω transmission lines terminated to ground |
| Rise/Fall Time | 37 ps (20/80) - preserves signal integrity for >8 GHz equivalent input bandwidth |
| Random Jitter | 200 fs RMS - minimizes bit error rate in high-speed serial link regeneration |
| Supply Voltages | VCCI = +5 V, VEE = −5 V - requires dual-rail supply for full input/output dynamic range |
| Operating Temp | −40°C to +125°C - qualified for industrial and automotive under-hood environments |
Pinout & Package
ADCMP580BCPZ-WP is housed in a 4 mm × 4 mm, 16-lead LFCSP (Lead Frame Chip Scale Package) with exposed thermal pad. The package supports fine-pitch PCB routing and enhanced thermal dissipation (θJA = 70°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VP, VN | Differential analog inputs | High-speed comparand inputs with internal 50 Ω termination; VTP/VTN provide separate return paths |
| LE, LE | Differential latch enable | Active-high latch mode (LE high, LE low); 50 Ω terminated to VTT (GND for ADCMP580) |
| Q, Q | Complementary CML outputs | Drive 400 mV into 50 Ω to ground; no level-shifting required for CML receivers |
| VCCI, VEE | Positive/negative supplies | +5 V and −5 V rails power the SiGe core; VCCI also powers latch logic |
| HYS | Hysteresis control | Connect to VEE via resistor to set hysteresis (1 mV typical with RHYS = ∞) |
| VTT | Latch termination reference | Must be tied to GND for ADCMP580 to bias LE/LE inputs correctly |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADCMP581BCPZ-WP | NECL outputs (−2 V termination), lower power (200 mW vs. 260 mW), different latch input voltage range (−1.8 V to +0.8 V) | Requires −2 V termination plane; suited for legacy ECL logic interfaces | Select when interfacing to existing −2 V–referenced ECL systems; not drop-in compatible due to VTT and output load requirements |
| TLV3501AIDBVR | CMOS output, 4.5 ns propagation delay, 2.7–5 V single supply, no on-chip termination | Lower speed, no CML drive capability; requires external termination and level-shifting | Choose only for cost-sensitive, non-critical timing applications where 180 ps delay is unnecessary |
Compared with ADCMP580BCPZ-WP, ADCMP581BCPZ-WP offers lower power but mandates −2 V termination infrastructure, while TLV3501AIDBVR sacrifices >25× speed and integrated termination for simplicity and single-supply operation-neither is pin-compatible or functionally interchangeable without board redesign.

FAQ
What is the recommended termination for ADCMP580BCPZ-WP CML outputs?
The ADCMP580BCPZ-WP CML outputs must be terminated to ground through 50 Ω resistors. Each output (Q and Q) is designed to deliver 400 mV into this load. The VTT pin must be connected to ground to properly bias the differential latch inputs. Improper termination causes signal reflection, increased jitter, and degraded pulse width dispersion performance.
Does ADCMP580BCPZ-WP support single-supply operation?
No, ADCMP580BCPZ-WP requires dual supplies: VCCI = +5 V and VEE = −5 V. These rails enable its −2 V to +3 V input voltage range and CML output swing. Attempting single-supply operation violates absolute maximum ratings and will damage the device or prevent functionality.
How is hysteresis configured on ADCMP580BCPZ-WP?
Hysteresis on ADCMP580BCPZ-WP is set by connecting the HYS pin to VEE (−5 V) through an external resistor. Leaving HYS open yields ~1 mV hysteresis; adding a resistor (e.g., 1 kΩ) increases hysteresis per Figure 8 in the datasheet. No internal pull-up or pull-down exists-configuration is purely resistor-dependent.
What is the function of VTP and VTN pins on ADCMP580BCPZ-WP?
VTP and VTN are dedicated return paths for the on-chip 50 Ω termination resistors at VP and VN inputs. They allow independent grounding or referencing of each termination, minimizing interaction between input channels and enabling flexible PCB layout. Both must be connected appropriately-floating them degrades common-mode rejection and increases offset drift.
Can ADCMP580BCPZ-WP operate without using the latch feature?
Yes. The latch can be disabled by pulling LE to VEE (−5 V) via a 1 kΩ resistor and tying LE to ground. This forces the comparator into continuous compare mode. The VTT pin must remain grounded. Disabling latch eliminates setup/hold timing constraints but retains full high-speed comparator functionality for asynchronous threshold detection.
