Product details
Overview
PTN3310D,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 800 Mbps typical data throughput, operates across –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,118 datasheet, PTN3310D,118 pinout, PTN3310D,118 application, or PTN3310D,118 equivalent, key selection criteria include LVDS-to-PECL translation direction, 800 Mbps throughput capability, 3.0–3.6 V supply compliance, differential input/output voltage thresholds, and SO8 thermal and layout compatibility.
Technical Context
The PTN3310D,118 implements a unidirectional, fully differential LVDS receiver stage followed by a PECL driver stage. Its internal architecture requires no external biasing or termination resistors for standard LVDS (100 mV min VID) and PECL (VCC-referenced VIH/VIL) signaling.
It delivers sub-3 ns propagation delay with <50 ps pulse skew and <100 ps part-to-part skew. The device maintains signal integrity under 100 mVPP supply noise and meets EIA-644 LVDS and PECL electrical standards at 3.3 V nominal supply.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS-to-PECL translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVDS387D | Supports bidirectional LVDS/PECL translation; requires external VBB bias for PECL inputs; 3.3 V only. | Used in mixed-direction backplane repeaters; not optimized for unidirectional optical module use cases. | Select when bidirectional translation or programmable direction control is required; verify VBB generation overhead. |
| MAX9122ESA+ | LVDS-to-CML output (not PECL); 2.5 V supply only; 600 Mbps max data rate. | Targeted at CML-based FPGA I/O interfaces, not optical laser drivers requiring PECL compliance. | Select only if interfacing to CML receivers; incompatible with PECL load termination and voltage thresholds. |

FAQ
What is the primary function of the PTN3310D,118?
The PTN3310D,118 is a unidirectional high-speed serial logic translator that converts differential LVDS input signals to PECL output signals. It operates from a single 3.3 V supply and delivers up to 800 Mbps throughput with sub-3 ns propagation delay. Its design eliminates the need for external biasing or termination components, making it ideal for optical transceiver module interfaces where signal integrity and board space are critical. The PTN3310D,118 is not bidirectional and does not support PECL-to-LVDS translation.
Does the PTN3310D,118 require external termination resistors?
No, the PTN3310D,118 does not require external termination resistors for standard LVDS input or PECL output operation. Its LVDS receiver is internally terminated to match 100 Ω differential impedance, and its PECL output stage is designed to drive standard 50 Ω loads to VCC via external pull-up resistors (typically 50 Ω to VCC). The PTN3310D,118 datasheet specifies operation with RL = 50 Ω per side for PECL outputs, and no additional series or parallel termination is needed on the IC side of the interface.
Can the PTN3310D,118 operate at 2.5 V supply?
No, the PTN3310D,118 is specified only for 3.0–3.6 V operation. Its PECL output stage is referenced to VCC and requires 3.3 V nominal to meet EIA-644 and PECL voltage thresholds (e.g., VOH ≥ 2.275 V, VOL ≤ 1.680 V). Operation below 3.0 V violates recommended operating conditions and risks failure to meet output swing, timing, or noise margin specifications. The PTN3310D,118 is not compatible with 2.5 V or 1.8 V systems.
What is the thermal rating of the PTN3310D,118 in SO8 package?
The PTN3310D,118 in SO8 (SOT96-1) package has a maximum junction temperature of +150 °C and operates over an ambient temperature range of –40 °C to +85 °C. Its thermal resistance (RθJA) is 110 K/W for standard JEDEC 2-layer board conditions. This rating supports deployment in sealed optical modules and telecom line cards where airflow is limited and ambient temperatures may exceed 70 °C during sustained operation.
Is the PTN3310D,118 pin-compatible with the PTN3311D,118?
Yes, the PTN3310D,118 and PTN3311D,118 share identical 8-pin SO8 (SOT96-1) pinouts and package dimensions, but they perform opposite translation functions: PTN3310D,118 is LVDS-in/PECL-out, while PTN3311D,118 is PECL-in/LVDS-out. Their pin assignments for GND, VCC, differential I/O, and package outline are identical, allowing PCB layout reuse when swapping directionality-provided system-level signal flow and termination schemes are verified for each configuration.
