SY100EPT23LZC

Translators, Level Shifters Overview

The SY100EPT23LZC 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 routing. The device provides two independent translation channels, accepting differential LVPECL inputs and driving LVTTL outputs with 24mA drive capability. Internal input resistors include pulldown on D and pullup/pulldown on /D, ensuring the Q output defaults LOW when inputs are open or grounded. It supports maximum frequencies exceeding 275MHz and is available in an 8-pin SOIC package.

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'ZC' against the manufacturer's current documentation to confirm lead finish and temperature range. The datasheet lists 'ZC' as a commercial grade part with Sn-Pb lead finish. Ensure compatibility with RoHS directives if required for the target application, noting that Pb-Free variants carry different suffixes such as 'ZG'. Confirm package type matches the Z8-1 designation.

Translators, Level Shifters Selection Notes

Select this component when interfacing LVPECL sources with LVTTL destinations requiring high-speed performance. The dual-gate architecture allows simultaneous processing of clock and data signals within a compact footprint. Verify that the system voltage aligns with the specified +3.3V requirement. Consider the internal resistor configuration for applications where input lines may remain unconnected during initialization.

Translators, Level Shifters FAQ

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

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

Does the SY100EPT23L require an external VBB reference?

No, the device does not require an external VBB reference because it utilizes LVPECL input levels referenced directly from the +3.3V supply.
