SY89329VMI-TR

Translators, Level Shifters Overview

The SY89329VMI-TR is a single-channel voltage level translator converting LVTTL/LVCMOS inputs to differential LVPECL outputs. It operates on a single 3.3V or 5.0V supply with a maximum power consumption of 20mA. The device supports frequencies up to 800MHz, featuring propagation delays under 100ps and ultra-low jitter specifications including less than 1ps RMS random jitter. Packaged in an 8-pin MLF (2mm x 2mm) format, it functions within a temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Converts single-ended LVTTL or LVCMOS logic levels into differential LVPECL signals for high-speed transmission.
• Operates using a single positive power supply without requiring negative voltage rails.
• Provides differential outputs that default to a HIGH state when the input signal is left floating.

Translators, Level Shifters Applications

• High-speed logic circuits
• Data communications systems
• Wireless communications systems
• Telecom systems

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'MI' against official manufacturer documentation to confirm lead finish and package variant details. Ensure compatibility with the required operating voltage range and thermal management requirements for the MLF package. Confirm RoHS compliance status through current datasheets before procurement.

Translators, Level Shifters Selection Notes

Select this component when space-constrained designs require translation between standard TTL/CMOS logic families and differential PECL signaling. It is suitable for applications demanding low power consumption and minimal propagation delay. Consider the dual-channel SY89322V if two independent translators are needed within the same footprint.

Translators, Level Shifters Part Context

This device belongs to the Precision Edge series by Micrel, now part of Microchip Technology. It is designed for high-frequency performance in compact form factors. The MLF package facilitates surface-mount assembly while maintaining electrical integrity for high-speed digital interfaces.

Translators, Level Shifters Replacement Considerations

The SY89322V serves as a dual-channel alternative within the same family. Cross-reference with other Micrel voltage translators for similar pinouts and electrical characteristics if direct substitution is required.

Translators, Level Shifters FAQ

What happens to the output if the input is left unconnected?

If the input is left floating, the Q output will default to a HIGH state.

Does the device require a negative power supply?

No, the device requires only a single positive supply of either 3.3V or 5.0V.
