SY58033UMI-TR

Clock Buffers, Drivers Overview

The SY58033UMI-TR is a high-speed, fully differential 1:8 fanout buffer featuring 400mV LVPECL outputs and internal termination. It operates on a 2.5V ±5% or 3.3V ±10% supply within the industrial temperature range of –40°C to +85°C. The device supports clock frequencies up to 5.5GHz with guaranteed propagation delay under 280ps and output skew below 20ps. It accepts input signals as low as 100mV via unique VT pin architecture for AC/DC coupling flexibility. Packaged in a 32-pin QFN (5mm x 5mm) in tape and reel format.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'MI' against official documentation, as standard listings often reference 'MG'. Confirm package type is QFN-32 and ensure compatibility with 2.5V or 3.3V power supplies. Check humidity sensitivity handling requirements prior to assembly.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring low-skew (<20ps) and low-jitter (<76fs) distribution of high-frequency clocks up to 5.5GHz. Ensure the design accommodates the 32-pin QFN package and provides adequate thermal management via the exposed pad. Verify input signal levels meet the minimum 100mV requirement for proper operation.

Clock Buffers, Drivers Part Context

The SY58033U belongs to Micrel’s Precision Edge® product line, designed for ultra-precision timing applications. It complements other devices like the CML-based SY58031U and the 800mV LVPECL SY58032U, offering a specialized solution for 400mV swing requirements with integrated input termination.

Clock Buffers, Drivers Replacement Considerations

Direct functional substitutes include the SY58031U (CML outputs) and SY58032U (800mV LVPECL outputs). Verify voltage swing compatibility and input interface requirements when considering these alternatives.
