NXP Semiconductors PTN3310DP,118

Overview

PTN3310DP,118 from NXP Semiconductors (formerly Philips) is a high-speed serial logic translator IC that converts differential LVDS inputs to PECL outputs in a single +3.3 V supply configuration. It supports up to 800 Mbps throughput, operates from –40 °C to +85 °C, and is housed in an 8-pin TSSOP package (SOT505-1). It enables interoperability between optical transceiver ICs in telecom backplane interfaces.

For engineers reviewing the PTN3310DP,118 datasheet, PTN3310DP,118 pinout, PTN3310DP,118 application, or PTN3310DP,118 equivalent, key selection criteria include LVDS-to-PECL translation direction, 800 Mbps max data rate, 3.0–3.6 V supply compliance, TSSOP8 thermal and layout constraints, and compatibility with SONET/SDH optical module signal integrity requirements.

Technical Context

The PTN3310DP,118 implements a unidirectional, fixed-function LVDS-to-PECL translation path using internal differential receiver and PECL driver circuitry. Its input stage meets EIA-644 LVDS standards with ≥100 mV differential sensitivity, while its output stage complies with PECL voltage levels (VOH = 2.275–2.420 V, VOL = 1.490–1.680 V at VCC = 3.3 V).

It requires no external biasing or termination resistors for standard operation, draws 13–20 mA supply current, and delivers sub-3 ns propagation delay with <50 ps pulse skew. The device is optimized for point-to-point optical module interconnects where signal integrity, low jitter, and minimal board-level redesign are critical.

FAQ

What is the primary function of the PTN3310DP,118?

The PTN3310DP,118 is a unidirectional high-speed serial logic translator that converts differential LVDS input signals to PECL output signals. It operates on a single +3.3 V supply and is optimized for use in optical transceiver modules, ATM, and SONET/SDH systems. Its fixed LVDS-in/PECL-out architecture ensures predictable timing behavior and eliminates configuration overhead - a key advantage over programmable or bidirectional alternatives. The PTN3310DP,118 delivers this functionality in an 8-pin TSSOP package with verified 800 Mbps throughput.

Does the PTN3310DP,118 require external termination resistors?

No, the PTN3310DP,118 does not require external termination resistors for standard operation. Its LVDS input stage is internally matched to accept 100 Ω differential termination, and its PECL output stage is designed to drive standard 50 Ω loads directly. The device specifies CL = 5 pF load capacitance for AC characterization, aligning with TIA-EIA-644 test conditions. External resistors may be added only for non-standard impedance matching or AC coupling networks - but these are application-specific and not part of the baseline PTN3310DP,118 implementation.

What is the maximum operating temperature range for the PTN3310DP,118?

The PTN3310DP,118 is rated for operation across an ambient temperature range of –40 °C to +85 °C, as specified in the recommended operating conditions table. This range is validated for continuous operation under full electrical load and meets industrial-grade reliability requirements. Junction temperature remains within safe limits (<150 °C) under typical board-level thermal conditions, supporting deployment in telecom chassis, outdoor cabinets, and dense optical modules where airflow is limited. All key parameters - including propagation delay, skew, and output voltage - are guaranteed across this full range for the PTN3310DP,118.

Can the PTN3310DP,118 be used in place of the PTN3310D (SO8 version)?

Yes, the PTN3310DP,118 is a pin-compatible TSSOP8 variant of the PTN3310D (SO8), sharing identical pinout, electrical specifications, and functional behavior. Both devices implement LVDS-to-PECL translation with the same 800 Mbps throughput, 1–3 ns propagation delay, and 3.0–3.6 V supply range. The only difference is package geometry: PTN3310DP,118 uses SOT505-1 (3 mm body width), while PTN3310D uses SOT96-1 (3.9 mm). Layout adaptation is required for footprint, but no schematic or firmware changes are needed for the PTN3310DP,118 to replace PTN3310D in existing designs.

Is the PTN3310DP,118 compliant with industry timing standards?

Yes, the PTN3310DP,118 meets EIA-644 LVDS input standards and PECL output voltage specifications referenced to VCC, both verified per the original Philips product data sheet. Its <50 ps pulse skew and sub-3 ns propagation delay comply with SONET OC-48 jitter accumulation budgets when used in point-to-point optical module interconnects. The device does not implement clock recovery or CDR functionality - it is a pure signal-level translator - so system-level timing compliance depends on proper board layout, termination, and upstream/downstream component selection. All timing parameters for the PTN3310DP,118 are measured and guaranteed under defined load and supply conditions.
