SY89327LMI-TR

Translators, Level Shifters Overview

The SY89327LMI-TR is a high-speed, fully differential translator manufactured by Microchip Technology. It accepts virtually all logic standards including single-ended SSTL, TTL, CMOS and differential LVDS, HSTL, CML, translating them to LVPECL outputs. The device guarantees AC performance up to a data rate of 2.5Gbps and a clock frequency of 2.5GHz. Key electrical parameters include a propagation delay of less than 400ps, rise/fall times under 200ps, and an ultra-low RMS phase jitter of 75fs. It operates on a 3.3V ±10% power supply with typical power consumption of 46mW.

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'MI' against official documentation to confirm package type and lead finish specifications. Ensure compatibility with the required operating temperature range of -40°C to +85°C for industrial applications. Confirm that external termination resistors are included in the design, as the device does not internally terminate its inputs.

Translators, Level Shifters Selection Notes

Select this component when interfacing mixed logic standards to LVPECL buses requiring low jitter and high throughput. Consider the 8-lead QFN package size for space-constrained designs. Verify that the application supports point-to-point interfaces, as multi-drop architectures are not supported due to input structure current requirements.

Translators, Level Shifters Part Context

The SY89327L belongs to Micrel’s Precision Edge family of high-speed logic devices. This family is characterized by ultra-small packaging options, high signal integrity, and operation across various supply voltages. The device is designed to bridge different signaling standards without internal termination, allowing flexibility for diverse interface requirements.

Translators, Level Shifters FAQ

Does the SY89327L support multi-drop or multi-point architectures?

No, only point-to-point interfaces are supported. Multi-drop and multi-point architectures are not supported due to the current required by the input structure.

How should unused inputs be handled?

Unused inputs must not be left floating. Tie either the true or complement input to ground. A logic zero is achieved by connecting the complement input to ground with the true input floating.
