SY733021UZG-TR

Translators, Level Shifters Overview

The SY733021UZG-TR is a 1-to-1 differential to LVCMOS/LVTTL translator manufactured by Micrel, now part of Microchip Technology. It operates on a 2.5V (±5%) or 3.3V (±10%) power supply and supports maximum frequencies up to 350MHz. The device accepts various differential input types including LVPECL, LVDS, LVHSTL, SSTL, and HCSL. It features an additive phase jitter of 90fsRMS at 100MHz within the 637kHz to 10MHz bandwidth range. Typical propagation delay is 1.9ns at 2.5V operation. The component is housed in an 8-pin SOIC package and is guaranteed for industrial temperature ranges from -40°C to +85°C.

Translators, Level Shifters Procurement Notes

Verify that the ordering suffix TR indicates tape and reel packaging rather than tube configuration. Confirm the specific voltage rating matches your system requirements as the device supports both 2.5V and 3.3V operations. Ensure compatibility with the 8-pin SOIC footprint during PCB layout. Check current manufacturer documentation for any updates regarding the transition from Micrel to Microchip Technology branding.

Translators, Level Shifters Selection Notes

Select this component when interfacing high-speed differential clock sources with standard TTL or CMOS logic inputs. Consider the 350MHz maximum frequency limit for signal integrity requirements. Evaluate the additive phase jitter specifications against system noise tolerance levels. Verify that the operating temperature range meets environmental constraints for the intended deployment location.

Translators, Level Shifters Part Context

This translator belongs to the Precision Edge product line originally developed by Micrel. It serves as a bridge between complex differential signaling environments and simpler single-ended logic domains. The device simplifies board design by eliminating external termination resistors for certain input types. It provides a compact solution for signal translation in dense electronic assemblies requiring precise timing alignment.

Translators, Level Shifters Replacement Considerations

The datasheet confirms pin-to-pin compatibility with IDT's ICS83021I. Verify electrical characteristics match before substitution. Ensure the replacement source acknowledges the Micrel origin of the original specification document.
