SY89306VMI TR

Overview

The SY89306VMI-TR is a high-speed differential buffer/receiver manufactured by Microchip Technology. It operates at frequencies up to 2.5 GHz with a typical propagation delay of 100 ps and duty cycle skew of 8 ps. The device supports 3.3 V to 5.5 V power supplies, drawing a maximum supply current of 48 mA. It features 100K PECL/ECL compatible inputs and outputs, including internal 75 kΩ pull-down resistors on the D and /D pins. The component is housed in an ultra-small 8-lead 2 mm x 2 mm DFN package and functions within an industrial temperature range of –40°C to +85°C.

Feature Summary

• Supports data rates exceeding 2.5 GHz with low propagation delay and minimal duty cycle skew for precise timing applications.
• Integrates internal 75 kΩ pull-down resistors on differential inputs to prevent floating states and ensure defined output levels.
• Includes a dedicated VBB reference voltage pin designed for single-ended AC-coupling configurations.

Applications

• High-speed clock distribution networks requiring differential signal buffering.
• PECL and ECL logic interface circuits in telecommunications equipment.
• Data acquisition systems utilizing AC-coupled differential input stages.

Procurement Notes

Verify the specific ordering suffix 'TR' corresponds to the tape and reel packaging configuration containing 1,000 units per reel. Confirm that the 'M' package designation matches the required 8-lead DFN footprint for your PCB layout. Ensure the 'G' suffix indicates the specified industrial temperature range and lead finish before finalizing procurement orders.

Selection Notes

Select this component when space constraints require an 8-lead DFN package instead of larger alternatives like the SY100EL16V. Choose this part if the design requires integrated input pull-down resistors to simplify termination networks. Verify that the operating voltage range of 3.0 V to 5.5 V aligns with the system power rails and that the 48 mA maximum current draw fits the thermal budget.

Part Context

This device belongs to the SY89 series of high-speed differential receivers and buffers from Microchip Technology. It serves as a compact alternative to legacy parts such as the SY100EL16V, offering a significantly smaller footprint while maintaining functional equivalence. The product line focuses on providing robust signal integrity solutions for high-frequency digital communication interfaces.

Replacement Considerations

The SY88927V is functionally equivalent but lacks the reduced footprint advantage. Designers replacing older SY100EL16V components should verify that the 8-lead DFN package dimensions are compatible with existing board layouts or tooling.

FAQ

What happens to the Q output if the D and /D inputs are left open?

Under open input conditions where the inputs are pulled to VEE, internal input clamps force the Q output to a LOW state.

How should the VBB pin be handled in AC-coupling applications?

The VBB pin provides a bias voltage of approximately VCC - 1.32 V. It must be bypassed to ground via a 0.01 μF capacitor and can only source or sink a maximum of 0.5 mA.

What is the maximum frequency guarantee for this device?

The maximum frequency is guaranteed for functionality at 2.5 GHz, provided the output voltage swing is at least 400 mV.
