Product details
Overview
PTN3310D,112 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 data throughput, operates from –40 °C to +85 °C, and is housed in an 8-pin SO package (SOT96-1). It enables interoperability between optical transceiver ICs in telecom backplane interfaces.
For engineers reviewing the PTN3310D,112 datasheet, PTN3310D,112 pinout, PTN3310D,112 application, or PTN3310D,112 equivalent, key selection criteria include LVDS-to-PECL translation direction, 800 Mbps max throughput, ±100 mVPP supply noise tolerance, 8-pin SO package compatibility, and compliance with EIA-644 and PECL standards.
Technical Context
The PTN3310D,112 implements a unidirectional LVDS receiver stage followed by a PECL driver stage, with no internal termination or level-shifting control logic. Its input stage meets EIA-644 LVDS specifications (≥100 mV differential amplitude), while its output stage delivers PECL-compliant voltage levels (VOH = 2.275–2.420 V, VOL = 1.490–1.680 V at VCC = 3.3 V).
Propagation delay is specified at 1–3 ns (differential path), with output skew ≤100 ps part-to-part and ≤50 ps pulse skew. The device requires matched 50 Ω loads on both differential outputs and operates only with a single 3.0–3.6 V supply - no separate VCCIO or bias rails are supported.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0–3.6 V - must be stable within ±100 mVPP noise for reliable 800 Mbps operation |
| Max Data Rate | 800 Mbps typical - defines maximum usable serial link speed in SONET/SDH line cards |
| Input Type | LVDS differential (VID ≥100 mV) - compatible with standard LVDS transceivers without external termination |
| Output Type | PECL differential (VOH/VOL referenced to VCC) - drives standard PECL fanout with 50 Ω termination to VCC − 2 V |
| Operating Temp | –40 °C to +85 °C - qualified for industrial-grade telecom equipment environments |
| Power Consumption | 13–20 mA ICC - determines thermal load in dense optical module PCB layouts |
| Package | SO8 (SOT96-1), 3.9 mm body width - surface-mount compatible with standard reflow profiles |
Pinout & Package
PTN3310D,112 is supplied in an 8-pin plastic small-outline (SO) package per SOT96-1 outline, with 1.27 mm lead pitch and 3.9 mm body width. Pin 1 is marked by a notch or dot; pins are numbered counter-clockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4 | GND1, GND2 | Separate ground returns for input and output sections - minimize crosstalk between LVDS and PECL domains |
| 2, 3 | VINP, VINN | Differential LVDS input pair - accepts standard 100 Ω-terminated LVDS signals; no internal termination |
| 5, 8 | VCC1, VCC2 | Single +3.3 V supply connections - both pins must be decoupled locally to reduce switching noise |
| 6, 7 | VOUTP, VOUTN | Differential PECL output pair - requires external 50 Ω termination to VCC − 2 V per PECL standard |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed serial logic translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVDS31DR | LVDS-to-LVDS repeater (not LVDS-to-PECL); 400 Mbps max; requires dual supplies for level shift | Only suitable where PECL output is not required - e.g., LVDS fanout extension, not logic family bridging | Select only if system uses LVDS end-to-end and needs signal regeneration, not translation |
| MAX9122ESA+ | LVDS-to-CML translator; 600 Mbps max; CML output incompatible with PECL-terminated lines without AC coupling | Requires redesign of termination network and may introduce DC offset issues in optical driver bias paths | Use only when interfacing to CML-based SerDes, not legacy PECL optical modules |
Compared with SN65LVDS31DR and MAX9122ESA+, the PTN3310D,112 uniquely delivers true LVDS-to-PECL conversion in a single 3.3 V supply, matching the electrical interface requirements of established telecom optical modules without external components or layout changes.

FAQ
What is the primary function of the PTN3310D,112?
The PTN3310D,112 is a dedicated unidirectional LVDS-to-PECL logic translator IC. It accepts differential LVDS input signals (minimum 100 mV amplitude) and produces compliant PECL output levels referenced to its single 3.3 V supply. Its purpose is to enable seamless electrical interface between LVDS-based host controllers and PECL-driven optical components - such as laser drivers - without external resistive networks or additional power rails. This function is explicitly defined in the Philips/NXP product data sheet for PTN3310D,112.
Does the PTN3310D,112 support bidirectional translation?
No, the PTN3310D,112 does not support bidirectional translation. It is strictly a one-way LVDS-to-PECL converter, as confirmed by its block diagram, pinout (VINP/VINN inputs only; VOUTP/VOUTN outputs only), and functional description in the official product data sheet. For PECL-to-LVDS translation, the companion part PTN3311D is required. The PTN3310D,112 contains no internal control logic, direction-select pins, or configurable I/O structures - its architecture is fixed and unidirectional by design.
What termination is required for the PECL outputs of the PTN3310D,112?
The PECL outputs of the PTN3310D,112 require external 50 Ω termination to VCC − 2 V, per standard PECL practice. The device itself provides no internal termination. This is specified in the "PECL outputs (PTN3310)" section of the AC and DC electrical characteristics tables, and confirmed by the recommended measurement configuration in Figure 3 of the datasheet. Failure to apply correct termination results in signal reflection, degraded eye diagrams, and failure to meet the 800 Mbps throughput specification for PTN3310D,112.
Can the PTN3310D,112 operate from a 2.5 V supply?
No, the PTN3310D,112 cannot operate from a 2.5 V supply. Its absolute maximum rating for VCC is +4.0 V, but the recommended operating range is strictly 3.0 V to 3.6 V. The PECL output voltage levels (VOH/VOL) are defined relative to VCC and track 1:1 with supply variation - at 2.5 V, output levels would fall outside PECL specification limits and fail to drive standard PECL loads. This requirement is documented in the "Recommended Operating Conditions" table of the PTN3310D,112 datasheet.
Is the PTN3310D,112 pin-compatible with the PTN3311D?
Yes, the PTN3310D,112 is pin-compatible with the PTN3311D - both share identical 8-pin SO (SOT96-1) and TSSOP (SOT505-1) packages and identical pin functions (GND1/GND2, VINP/VINN, VCC1/VCC2, VOUTP/VOUTN). However, their internal signal flow differs: PTN3310D,112 is LVDS-in/PECL-out, while PTN3311D is PECL-in/LVDS-out. This pin compatibility allows board reuse across both translation directions, provided the BOM and routing match the required signal direction for PTN3310D,112.
