Product details
Overview
ADCMP582BCPZ-RL7 from Analog Devices is an ultrafast SiGe voltage comparator with PECL 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, 8 GHz equivalent input bandwidth, and operates across −40°C to +125°C with ±5 V analog supplies and +3.3 V logic supply.
For engineers reviewing the ADCMP582BCPZ-RL7 datasheet, ADCMP582BCPZ-RL7 pinout, ADCMP582BCPZ-RL7 application, or ADCMP582BCPZ-RL7 equivalent, key selection criteria include PECL-compatible output drive (400 mV into 50 Ω terminated to VCCO − 2 V), resistor-programmable hysteresis, differential latch control with 30 ps setup time, and on-chip 50 Ω input terminations enabling direct 50 Ω system interface without external resistors.
Technical Context
The ADCMP582BCPZ-RL7 implements a fully differential SiGe bipolar comparator core with independent VP/VN inputs, each featuring internal 50 Ω termination referenced to VTP/VTN pins. Its PECL output stage drives 50 Ω loads terminated to VCCO − 2 V, supporting rail-to-rail input range (−2 V to +3 V) under ±5 V supplies while maintaining <15 ps overdrive dispersion and 25 ps deterministic jitter at 10 Gbps.
Differential latch control (LE/LE) enables precise edge-triggered sampling with 100 ps minimum pulse width and 30 ps setup time; hysteresis is externally set via HYS pin connected to VEE through a resistor, allowing programmable thresholds from 1 mV upward. The device uses a 16-lead LFCSP package with exposed pad for thermal management and requires dedicated VTT biasing at VCCO − 2 V for latch input termination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 180 ps - Enables sub-100 ps timing resolution in 10 Gbps clock/data recovery paths. |
| Output Rise/Fall Time | 37 ps (20/80) - Supports clean 12.5 Gbps toggle rate with minimal pulse distortion. |
| Input Voltage Range | −2 V to +3 V - Accommodates wide-swing analog signals without external level shifting. |
| Output Drive | 400 mV into 50 Ω terminated to VCCO − 2 V - Directly interfaces with PECL logic and back-terminated transmission lines. |
| Hysteresis Control | Resistor-programmable via HYS pin - Allows precise noise immunity tuning (e.g., 10 mV with ~500 Ω resistor). |
| Latch Setup Time | 30 ps - Enables tight timing margins in high-speed sampling circuits with minimal hold-time violation risk. |
| Random Jitter | 200 fs RMS - Critical for low-bit-error-rate operation in serial data links and precision timing applications. |
Pinout & Package
ADCMP582BCPZ-RL7 is housed in a 16-lead 3 mm × 3 mm LFCSP package with exposed thermal pad. Pin functions are optimized for high-speed layout: differential inputs (VP/VN) and outputs (Q/Q) are placed opposite each other to minimize coupling; dedicated VTP/VTN and VTT pins enable controlled termination; dual ground pins (GND, Pins 9 & 15) and separate VCCI/VEE/VCCO supplies support low-inductance power delivery.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VTP) | VP input termination return | Connects to system ground or termination reference to complete 50 Ω input match at VP. |
| 2 (VP) | Noninverting analog input | Differential input node with on-chip 50 Ω termination; accepts −2 V to +3 V common-mode range. |
| 3 (VN) | Inverting analog input | Differential input node with on-chip 50 Ω termination; used with VP for threshold comparison. |
| 4 (VTN) | VN input termination return | Connects to system ground or termination reference to complete 50 Ω input match at VN. |
| 6 (LE) | Inverting latch enable | Active-low control: when high, output latches prior input state; must be driven complementarily with LE. |
| 7 (LE) | Noninverting latch enable | Active-high control: when high, output tracks input; complements LE for differential latch signaling. |
| 8 (VTT) | Latch input termination reference | Must be biased at VCCO − 2 V to properly terminate LE/LE differential pair in PECL mode. |
| 10 (Q) | Inverting output | PECL-compatible output; logic low when VP > VN in compare mode; drives 400 mV into 50 Ω to VCCO − 2 V. |
| 11 (Q) | Noninverting output | PECL-compatible output; logic high when VP > VN in compare mode; complementary to Q. |
| 13 (VEE) | Negative supply | −5 V supply rail; requires low-inductance bypassing due to high di/dt during output switching. |
| 14 (HYS) | Hysteresis control | Connect to VEE via resistor to set hysteresis voltage; open for zero hysteresis. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low propagation delay dispersion | <15 ps overdrive/slew rate variation ensures consistent timing across input signal amplitudes and slopes. |
| Integrated 50 Ω input terminations | Eliminates need for external resistors at VP/VN, reducing board space and parasitic mismatch in 50 Ω systems. |
| Programmable hysteresis | Adjustable via single external resistor on HYS pin, enabling tailored noise immunity without redesign. |
| Differential latch interface | 50 Ω-terminated LE/LE inputs with VTT reference allow robust, low-skew sampling synchronized to system clocks. |
| PECL output compatibility | Direct drive into 50 Ω loads terminated to VCCO − 2 V meets JEDEC PECL standards without level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADCMP581BCPZ-RL7 | NECL output stage (−2 V termination); 180 ps delay; same pinout but VTT = −2 V, not VCCO − 2 V. | Requires −2 V termination rail instead of VCCO − 2 V; compatible with legacy ECL logic families. | Select when interfacing with existing −2 V–referenced ECL systems; not drop-in for PECL designs. |
| TLV3501CDR | CMOS output; 4.5 ns propagation delay; 2.7–5.5 V single supply; no integrated termination or latch. | Lower speed, lower power, no differential latch; suited for cost-sensitive, non-50 Ω embedded systems. | Choose for sub-Gbps applications where layout simplicity and supply flexibility outweigh speed requirements. |
Compared with ADCMP582BCPZ-RL7, ADCMP581BCPZ-RL7 offers identical speed but requires different termination infrastructure, while TLV3501CDR trades 40× higher delay for single-supply operation and reduced BOM count-making each suitable only within distinct system architecture constraints.

FAQ
What is the recommended termination for ADCMP582BCPZ-RL7 PECL outputs?
The ADCMP582BCPZ-RL7 PECL outputs must be terminated to VCCO − 2 V using a 50 Ω resistor. For VCCO = 3.3 V, this means termination at +1.3 V. This matches the output stage's design specification and ensures 400 mV differential swing into 50 Ω. Incorrect termination (e.g., to ground or VCCO) causes signal degradation, increased jitter, and potential latch-up.
How is hysteresis configured on ADCMP582BCPZ-RL7?
Hysteresis on ADCMP582BCPZ-RL7 is set by connecting the HYS pin to VEE (−5 V) through an external resistor. A 1 kΩ resistor yields ~5 mV hysteresis; values from 0 Ω (max hysteresis) to open-circuit (zero hysteresis) are supported. The relationship is linear per Figure 8 in the datasheet, enabling precise noise margin tuning without circuit modification.
Does ADCMP582BCPZ-RL7 require external input termination resistors?
No. ADCMP582BCPZ-RL7 integrates 50 Ω termination resistors at both VP and VN inputs. These are referenced to VTP and VTN pins respectively, which must be connected to the appropriate system reference (typically ground for CML-style use, but configurable). External resistors are unnecessary unless custom termination impedance is required.
What is the function of the VTT pin on ADCMP582BCPZ-RL7?
The VTT pin on ADCMP582BCPZ-RL7 serves as the termination reference for the differential latch enable inputs (LE/LE). It must be biased at VCCO − 2 V (e.g., +1.3 V when VCCO = 3.3 V) to correctly terminate the 50 Ω internal resistors on those pins. Leaving VTT unconnected or misbiased degrades latch timing accuracy and increases setup/hold violations.
Can ADCMP582BCPZ-RL7 operate with VCCO = 2.5 V?
Yes. ADCMP582BCPZ-RL7 supports VCCO from +2.5 V to +5.0 V per the Absolute Maximum Ratings and DC Specifications tables. At VCCO = 2.5 V, the PECL output termination point becomes +0.5 V (VCCO − 2 V), and output voltage levels shift accordingly-VOH ≈ −0.5 V, VOL ≈ −1.0 V (differential ~500 mV). System-level signal integrity must be verified at this condition.
