PTN3311D,112

Translators, Level Shifters Overview

The PTN3311D,112 is a high-speed serial logic translator designed for optical transceiver modules. It converts PECL differential inputs to LVDS differential outputs, meeting EIA-644 and PECL standards. Operating on a single +3.3 V supply, it supports a typical maximum throughput data rate of 800 Mbps. The device features low propagation delay (typical 1 ns) and operates within an ambient temperature range of -40 °C to +85 °C. It is housed in an 8-pin SO package.

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix '112' against current NXP documentation to confirm package type and environmental compliance status. Confirm that the component meets RoHS requirements if applicable to your design constraints. Ensure the datasheet version matches the production batch specifications.

Translators, Level Shifters Selection Notes

Select this component when interfacing PECL source devices with LVDS destination receivers in optical module designs. It serves as a direct replacement for legacy translators, simplifying the integration of mixed-voltage logic families. Consider the 800 Mbps throughput limit and 3.3 V supply requirement during system architecture planning.

Translators, Level Shifters Part Context

This part belongs to the PTN3310/PTN3311 family of high-speed serial logic translators manufactured by Philips/NXP Semiconductors. The PTN3311 variant specifically handles PECL input to LVDS output conversion, complementing the PTN3310 which performs the reverse function. Both are optimized for compact optical module applications.

Translators, Level Shifters Replacement Considerations

The PTN3310D is the complementary pin-for-pin compatible device for LVDS-to-PECL translation. Verify signal direction requirements before substitution. No other direct functional substitutes are documented in the provided datasheet.

Translators, Level Shifters FAQ
