SY100EPT23LZI

Translators, Level Shifters Overview

The SY100EPT23LZI is a dual differential LVPECL-to-LVTTL translator manufactured by Microchip Technology. It operates on a single +3.3V power supply and features flow-through pinouts for simplified circuit design. The device supports maximum input frequencies exceeding 275MHz with a typical propagation delay of 1.9ns. It is housed in an 8-pin SOIC package and is rated for industrial operating temperatures ranging from -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Dual differential LVPECL inputs translate directly to LVTTL outputs
• Internal pulldown and pullup resistors ensure LOW output default when inputs are open or grounded
• Compatible with ECL 100K standard and accepts 10K voltage levels
• Designed for translating clock and data signals in compact applications

Translators, Level Shifters Applications

• Clock signal translation
• Data signal translation
• LVPECL to LVTTL interface circuits

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'ZI' confirms the Industrial temperature range (-40°C to +85°C) and the 8-pin SOIC package type. Confirm lead finish specifications if RoHS compliance is required, as standard versions may use Sn-Pb while Pb-Free variants carry specific bar-line indicators. Ensure the source document explicitly lists this part number variant.

Translators, Level Shifters Selection Notes

Select this component when a dual-channel translator is needed between LVPECL sources and LVTTL destinations. The internal biasing eliminates external resistor requirements for open inputs. Verify that the 3.3V supply constraint aligns with the system power architecture and that the 8-pin footprint fits the PCB layout constraints.

Translators, Level Shifters Part Context

This device belongs to the SY100ELT23L family of Precision Edge translators. It is specifically designed for the ECL 100K logic standard. Unlike other variants, it does not require an external VBB reference because it lacks LVPECL outputs. The manufacturer acquired Micrel, which originally developed this product line.

Translators, Level Shifters FAQ

What happens to the Q output if the differential inputs are left open?

The Q output will default to a LOW state when the inputs are open or at ground potential due to internal biasing.

Does this device require an external VBB reference voltage?

No, the device does not require an external VBB reference because it does not have LVPECL outputs.
