MAX9152EUE+T

Overview

The MAX9152EUE+T is an 800Mbps LVDS/LVPECL-to-LVDS 2 x 2 crosspoint switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3.3V supply, consuming 109mW of power within the -40°C to +85°C temperature range. The device features two differential inputs and two outputs, supporting configurations such as 2:1 mux, 1:2 demux, 1:2 splitter, or dual repeater. It delivers ultra-low 120ps peak-to-peak jitter at 800Mbps with PRBS = 2^23-1 data pattern and maintains less than 50ps channel-to-channel skew.

Feature Summary

• Pin-programmable configuration supports multiple modes including 2x2 crosspoint switch, 2:1 mux, 1:2 demux, 1:2 splitter, and dual repeater.
• Ultra-low jitter performance ensures reliable communications in high-speed links sensitive to timing errors.
• Inputs accept both LVDS and LVPECL signals directly without external level shifting for LVPECL.
• Selectable differential output resistance minimizes reflections on interconnects.

Applications

• Protection switching in fault-tolerant systems
• Loopback diagnostics for signal verification
• Clock and data distribution fanout buffering
• Signal regeneration over extended communication distances

Procurement Notes

Verify the specific ordering suffix EUE corresponds to the 16-pin TSSOP package required for your design. Confirm the temperature grade matches your operational environment requirements. Ensure logic levels for SEL and EN pins align with your system's control voltage standards. Cross-reference the datasheet revision date to confirm current specifications before finalizing procurement.

Selection Notes

Select this component when low jitter and flexible routing are critical for high-speed differential signaling. Consider the 16-pin TSSOP package size if board space is limited compared to the SO package. Evaluate the need for selectable output impedance based on your transmission line characteristics. Ensure compatibility with LVDS or LVPECL source drivers for optimal signal integrity.

Part Context

This part belongs to the MAX9152 series of analog crosspoint switches designed for high-speed data distribution. It serves as a pin-compatible upgrade to the DS90CP22 in the SO package variant. The device integrates CMOS technology with 880 transistors to provide efficient signal routing in networking and telecommunications equipment.

Replacement Considerations

The MAX9152EUE+T is a pin-compatible alternative to the DS90CP22 when using the SO package format. Verify that any substitute component supports the same 800Mbps data rate and LVDS/LVPECL input compatibility. Check if the replacement offers similar jitter performance and configurable operating modes.
