SY100EPT23LKG

Translators, Level Shifters Overview

The SY100EPT23LKG is a dual differential LVPECL-to-LVTTL translator manufactured by Microchip Technology. It operates on a single +3.3V power supply and features a typical propagation delay of 1.9ns with a maximum frequency exceeding 275MHz. The device provides 24mA LVTTL outputs and includes internal input resistors for pulldown on D and pullup/pulldown on /D inputs. It is housed in an 8-pin MSOP package (K8-1) and supports an operating temperature range from -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Dual differential LVPECL inputs translate directly to standard LVTTL outputs
• Flow-through pinout design simplifies PCB layout for clock and data signals
• Internal input resistors ensure defined logic states when inputs are open or grounded

Translators, Level Shifters Applications

• Translation of differential clock signals to LVTTL domains
• Data signal translation between LVPECL sources and LVTTL receivers
• High-speed interface bridging in communication equipment

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'KG' corresponds to the Industrial temperature grade (-40°C to +85°C), Pb-Free status, and 8-pin MSOP package type as listed in the official datasheet. Confirm that the component is sourced from authorized channels to ensure authenticity and compliance with RoHS directives. Cross-reference the manufacturer part number against current Microchip documentation to validate availability and revision status before procurement.

Translators, Level Shifters Selection Notes

Select this component when interfacing LVPECL sources with LVTTL loads requiring high-speed performance up to 275MHz. The dual-gate architecture allows simultaneous processing of two independent differential pairs within a compact footprint. Ensure the application environment remains within the specified industrial temperature range and utilizes a stable 3.3V power supply to maintain electrical characteristics.

Translators, Level Shifters Part Context

This device belongs to the ECL Pro™ family, designed for low-voltage positive ECL applications. It bridges legacy high-speed differential signaling standards with modern TTL-compatible logic levels. The integration of internal termination resistors reduces external component count, making it suitable for space-constrained designs requiring reliable level shifting without complex biasing networks.

Translators, Level Shifters Replacement Considerations

SY100EPT23LZG: Identical function in SOIC-8 package; verify pin compatibility if switching packages.

Translators, Level Shifters FAQ

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

The Q output will default to a LOW state if the inputs are open or at ground due to the internal input resistor configuration.

Does the SY100EPT23L require an external VBB reference voltage?

No, the device does not require an external VBB reference because it lacks LVPECL outputs and is designed to operate solely on a +3.3V supply and ground.
