Analog Devices Inc./Maxim Integrated MAX9360EKA/GG8

Overview

The MAX9360EKA/GG8 from Maxim Integrated is a 3.3V LVTTL/CMOS-to-differential LVECL/ECL translator in an 8-pin SOT23 package, delivering 440ps typical propagation delay, 3GHz toggle frequency, and 550mV differential output swing. It operates with VCC = 3.0–3.6V and VEE = –2.375V to –5.5V, and is used in high-speed clock/data distribution systems interfacing CMOS logic to ECL/LVECL receivers.

For engineers reviewing the MAX9360EKA/GG8 datasheet, MAX9360EKA/GG8 pinout, MAX9360EKA/GG8 application, or MAX9360EKA/GG8 equivalent, key selection criteria include input voltage compatibility (3.3V LVTTL/CMOS), differential output drive capability into –2V-terminated 50Ω loads, ultra-low skew performance, and thermal behavior under industrial temperature range (–40°C to +85°C).

Technical Context

The MAX9360EKA/GG8 implements a bipolar-based single-channel translation architecture that accepts standard LVTTL/CMOS inputs and generates complementary LVECL/ECL outputs referenced to GND and VEE. Its internal pullup ensures Q/Q default to high when D is open, eliminating floating-input risk.

It supports two output voltage regimes: ECL mode (VEE = –4.2V to –5.5V) and LVECL mode (VEE = –2.375V to –3.8V), with guaranteed 550mV minimum differential swing across –40°C to +85°C and >300mV output amplitude at 1GHz.

FAQ

What is the maximum operating frequency supported by the MAX9360EKA/GG8?

The MAX9360EKA/GG8 supports a maximum toggle frequency of 3.0GHz when differential output swing is ≥300mV, and 1.5GHz when swing is ≥500mV. This specification is measured under standard load conditions (50Ω to –2V) and applies across the full industrial temperature range (–40°C to +85°C). The MAX9360EKA/GG8 achieves this using a bipolar process optimized for speed and low skew.

Does the MAX9360EKA/GG8 require external pull-up resistors on the D input?

No, the MAX9360EKA/GG8 does not require external pull-up resistors on the D input. It features internal pullup circuitry that drives the Q and Q outputs to a differential high state when the D input is disconnected or left floating. This eliminates the need for external components and ensures predictable startup behavior in systems with intermittent or configurable inputs.

What are the recommended power supply bypassing practices for the MAX9360EKA/GG8?

For the MAX9360EKA/GG8, bypass both VCC and VEE to GND using parallel 0.1µF and 0.01µF ceramic capacitors placed as close as possible to the respective pins, with the 0.01µF capacitor nearest the device. Use multiple vias to minimize inductance. This configuration suppresses high-frequency supply noise and prevents jitter degradation caused by supply coupling into the sensitive ECL output stage of the MAX9360EKA/GG8.

Can the MAX9360EKA/GG8 drive standard ECL loads as well as LVECL loads?

Yes, the MAX9360EKA/GG8 can drive both standard ECL and LVECL loads. When VEE is set to –4.2V to –5.5V, output levels conform to standard ECL specifications; when VEE is –2.375V to –3.8V, they meet LVECL requirements. The MAX9360EKA/GG8 maintains 550mV minimum differential swing across both modes and is fully compatible with common –2V-terminated 50Ω loads used in either family.

What is the thermal resistance (θ_JA) of the MAX9360EKA/GG8 in its SOT23 package?

The MAX9360EKA/GG8 in its 8-pin SOT23 package has a junction-to-ambient thermal resistance (θ_JA) of 112°C/W under still-air conditions, and 78°C/W with 500LFPM airflow. This value is confirmed in the Absolute Maximum Ratings table and enables reliable operation at 13.8mA typical IEE supply current across the full –40°C to +85°C temperature range without exceeding the 150°C maximum junction temperature limit.
