Analog Devices Inc./Maxim Integrated MAX9602EUG

Overview

MAX9602EUG from Maxim Integrated is a quad-channel, ultra-high-speed PECL-output comparator with 500ps propagation delay, 10ps channel-to-channel skew, and 30ps propagation delay dispersion-designed for high-fidelity pulse tracking in VLSI ATE, high-speed instrumentation, and logic analyzer front ends.

For engineers reviewing the MAX9602EUG datasheet, MAX9602EUG pinout, MAX9602EUG application, or MAX9602EUG equivalent, this page delivers verified electrical specs, package mapping to 24-pin TSSOP, functional role as a quad differential comparator without latch enable or hysteresis, and real-world timing constraints including 4Gbps tracking frequency and -1.2V to +4V input common-mode range under +6V/-4.2V supplies.

Technical Context

The MAX9602EUG implements a fully differential bipolar comparator core optimized for minimal propagation delay variation across channels and input conditions. Its architecture supports direct 50Ω transmission-line driving via open-emitter PECL outputs referenced to VCCO_, with separate output driver supplies (VCCOA–VCCOD) per channel pair.

No latch-enable (LE_/LE_) or hysteresis (HYS_) pins are present-unlike MAX9600/MAX9601-making it a pure high-speed compare-only device. Input common-mode range spans (VEE + 3V) to (VCC − 2V), and propagation delay dispersion remains ≤40ps across overdrive (100mV–2V), slew rate (0.2–10V/ns), duty cycle (10%–90%), and temperature (−40°C to +85°C).

Key Specifications

Pinout & Package

MAX9602EUG is housed in a 24-pin Thin Shrink Small Outline Package (TSSOP) with 0.65mm pitch, exposed pad for thermal dissipation, and JEDEC MO-153 compliant footprint. Pin numbering follows standard counter-clockwise orientation from pin 1 (top-left corner, marked dot).

Compared with MAX9602EUG, MAX9601EUP adds latch and hysteresis at the cost of channel count and package size, while ADCMP572 offers faster delay but sacrifices integration density, supply flexibility, and input voltage range - making MAX9602EUG optimal for quad-channel, wide-supply, high-fidelity pulse tracking.

FAQ

What is the maximum data rate supported by the MAX9602EUG?

The MAX9602EUG supports a 4Gbps tracking frequency, meaning it can reliably compare differential input signals toggling at up to 4 billion transitions per second. This capability is validated under specified conditions: 100mV input overdrive, 5pF load, and 50Ω termination. The 500ps propagation delay and ≤40ps delay dispersion ensure accurate edge alignment at this rate. MAX9602EUG achieves this without internal latch or hysteresis, making it ideal for continuous high-speed waveform validation rather than sampled decision logic.

Does the MAX9602EUG include latch enable or hysteresis functionality?

No, the MAX9602EUG does not include latch enable (LE_/LE_) or hysteresis (HYS_) pins. Unlike the MAX9600EUP and MAX9601EUP, which provide these features for track-hold operation and noise immunity, the MAX9602EUG is a dedicated quad comparator optimized solely for ultra-low-latency, high-fidelity signal comparison. Its pinout omits those control inputs entirely, and its internal circuitry lacks the associated logic. Therefore, MAX9602EUG must be used in free-running compare mode only.

What are the required external components for proper operation of the MAX9602EUG?

The MAX9602EUG requires external 50Ω pull-down resistors from each Q/Q̅ output to a termination voltage VT (typically 3V when VCCO_ = 5V), as its open-emitter PECL outputs sink current. It also needs local 0.01µF ceramic decoupling capacitors placed as close as possible to each VCC, VEE, and VCCOx pin. No hysteresis resistor is needed since HYS_ pins are absent. Input traces must be tightly coupled differential pairs with controlled impedance to minimize skew and reflections - MAX9602EUG's performance depends critically on proper PCB layout and termination.

How does the MAX9602EUG handle different supply configurations?

The MAX9602EUG supports two standard supply configurations: −5.2V/+5V and −4.2V/+6V. The input common-mode range adjusts accordingly - (VEE + 3V) to (VCC − 2V) - yielding −2.2V to +3V or −1.2V to +4V respectively. Output driver supplies (VCCOA–VCCOD) are independent and must match the desired PECL logic level (e.g., 5V for standard PECL). VCC powers the core comparator; VEE is shared across all channels; and each VCCOx rail isolates its respective output stage to reduce crosstalk. All supplies must be well-decoupled.

What is the significance of propagation delay dispersion in the MAX9602EUG?

Propagation delay dispersion quantifies how much the MAX9602EUG's 500ps delay varies with input conditions - such as overdrive (100mV–2V), slew rate (0.2–10V/ns), duty cycle (10%–90%), or common-mode voltage. MAX9602EUG maintains ≤40ps dispersion across all tested conditions, ensuring consistent timing behavior regardless of signal shape or amplitude. This stability is essential in ATE and instrumentation where edge placement accuracy directly impacts measurement validity - unlike comparators with higher dispersion, MAX9602EUG avoids timing ambiguity during pulse-width or jitter analysis.
