MAX9392EHJ+

Analog Switches - Special Purpose Overview

The MAX9392EHJ+ is a dual 2 x 2 crosspoint switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 3.0V to 3.6V supply within an extended temperature range of -40°C to +85°C. The device multiplexes differential inputs to LVDS outputs, supporting HSTL and LVDS standards with high-level input fail-safe detection. Key electrical parameters include a maximum switching frequency of 1.5GHz, a typical supply current of 98mA at VCC = 3.3V, and a differential output voltage of 250mV to 450mV into a 100Ω load. Propagation delays range from 286ps to 574ps, with added random jitter limited to 2ps RMS and deterministic jitter up to 98ps P-P.

Analog Switches - Special Purpose Feature Summary

• Configurable as a 2x2 crosspoint switch, 2:1 mux, 1:2 splitter, or dual repeater via LVCMOS/LVTTL logic inputs
• High-speed signal distribution optimized for low power consumption and low noise applications
• Fail-safe circuitry forces outputs to a differential low state when inputs are undriven or out of common-mode range

Analog Switches - Special Purpose Applications

• Protection switching in fault-tolerant systems
• Loopback switching for diagnostics
• Fanout buffering for clock and data distribution
• Signal regeneration in high-speed links

Analog Switches - Special Purpose Procurement Notes

Verify the component authenticity through authorized distributors or direct manufacturer channels. Confirm that the package marking matches the 32-pin TQFP specification and check the RoHS compliance status for lead-free requirements. Ensure the operating environment remains within the specified -40°C to +85°C temperature range during deployment.

Analog Switches - Special Purpose Selection Notes

Select the MAX9392EHJ+ specifically for applications requiring compatibility with LVDS and HSTL signaling standards. This variant provides high-level input fail-safe detection suitable for GND-referenced differential inputs. Consider the MAX9393 variant if the design utilizes LVPECL or CML signals requiring low-level fail-safe detection instead.

Analog Switches - Special Purpose Part Context

This component belongs to the MAX9392/MAX9393 family of anything-to-LVDS dual 2 x 2 crosspoint switches. It serves as a functional alternative to the MAX9390/MAX9391 series, which offers a crossflow pin configuration. Both families share similar performance characteristics but differ in internal routing topology and pin assignments.

Analog Switches - Special Purpose Replacement Considerations

The MAX9393EHJ+ is a compatible substitute within the same family, distinguished by its support for LVPECL and CML inputs rather than HSTL/LVDS. Verify pin compatibility and logic level requirements before substitution.
