SN65LVDS100DGK Descripción general
A differential buffer, repeater or translator is an interface IC that sits in a high-speed serial signal path: its receiver accepts one differential logic family (LVDS, PECL/LVPECL or CML) and its driver re-transmits the same data as clean LVDS. In the signal-integrity hierarchy, it sits between physical transceivers and transmission media such as backplanes, cables and clock trees, where signal degradation would otherwise exceed receiver margin.
Key features include operation at signaling rates of 2 Gbps and above, low 100 ps maximum part-to-part skew, 25 mV of receiver input threshold hysteresis over a 0V to 4V common-mode input range, and positioning as a low-power alternative to the MC100EP16 ECL receiver. The wide input common-mode range allows it to accept LVPECL and CML levels while always driving a standard LVDS output.
Technically, the SN65LVDS100 is formed from an input differential receiver with hysteresis followed by an LVDS output driver compliant with EIA/TIA-644 (LVDS) signaling. The device supports an additional VBB reference output of typically 1.35V below VCC, which is particularly useful for receiving single-ended 3.3V PECL inputs. Total jitter is specified for signaling rates up to 2 Gbps, and ESD tolerance exceeds 2000V per the human-body-model test referenced on the product page.
Typical applications include clock distribution and jitter cleaning in networking and telecom line cards, backplane signal re-driving in industrial automation, and high-speed point-to-point links between FPGAs, ASICs and serializers where input signal quality has degraded after long traces or connectors.
Design-wise, maintain a solid 3.3V supply with low-inductance 0.1uF plus 10uF decoupling, keep differential traces impedance-controlled at 100 ohms, and remember the maximum supply range of 3V to 3.6V. Place the part close to connectors to maximize the regenerated link margin.

Aplicaciones típicas
SN65LVDS100DGK es adecuado para 6 aplicacións: Clock Distribution and Jitter Cleaning, Backplane Signal Re-driving, FPGA-to-ASIC High-Speed Interconnect, Industrial Automation Data Links, Test and Measurement Instruments, Medical Imaging Equipment.
Clock Distribution and Jitter Cleaning
In networking and telecom line cards, a central clock must reach serializers, FPGAs and PHYs across long PCB traces whose losses slow edges and shrink eye margin. The SN65LVDS100DGK re-drives the clock: its receiver accepts the degraded LVDS, LVPECL or CML waveform with 25 mV of hysteresis over a 0V to 4V common-mode range, and its driver re-launches a full-swing LVDS signal designed for rates of 2 Gbps and above. With 100 ps maximum part-to-part skew, multiple cascaded buffers keep clock trees aligned. Place the repeater immediately after the backplane or clock source to maximize regenerated margin, and use the VBB output (typically 1.35V below VCC) when biasing single-ended 3.3V PECL clock inputs.
Recomendado
Backplane Signal Re-driving
High-speed serial links across backplanes suffer attenuation, reflection and intersymbol interference at gigabit rates. The SN65LVDS100DGK acts as a mid-span or end-point repeater: the differential receiver tolerates the degraded signal (CML, LVPECL or LVDS levels within the 0V to 4V common-mode window), and the LVDS driver restores edge rates for the remaining segment at signaling rates up to 2 Gbps. TI positions it as a low-power alternative to the MC100EP16 ECL receiver, reducing card power budget versus PECL solutions. Its 470 ps typical propagation delay must be budgeted in the link timing, and the small 8-pin VSSOP (DGK) package lets the repeater sit directly at the connector where the signal enters the card.
Recomendado
FPGA-to-ASIC High-Speed Interconnect
Point-to-point links between FPGAs, ASICs and serializers frequently mix logic families: an ASIC CML output feeding an FPGA LVDS input, or a 3.3V PECL clock entering an LVDS bank. The SN65LVDS100DGK solves both level translation and buffering in one device, accepting CML, LVPECL or LVDS at rates up to 2 Gbps and driving standard EIA/TIA-644 LVDS output. The 25 mV hysteresis rejects ground-bounce-induced false switching, and exceeding 2000V HBM ESD tolerance adds robustness during board assembly. Design with 100-ohm controlled-impedance differential pairs, keep the 3V to 3.6V supply clean, and verify timing closure including the 470 ps typical repeater delay.
Recomendado
Industrial Automation Data Links
Factory automation and machine-vision systems move high-rate serial data between cameras, drives and controllers in electrically noisy environments. The SN65LVDS100DGK operates from -40C to +85C, covering industrial ambient extremes, and its differential LVDS signaling provides inherent common-mode noise immunity. Re-driving signals after long cable runs or noisy wire harnesses restores the 2-Gbps-class eye diagram, while 25 mV of receiver hysteresis prevents noise-triggered glitches. ESD protection exceeding 2000V HBM withstands handling and in-field service. Use the repeater at each cable termination point and consider the SN65LVDT variant where the VBB reference is not needed.
Recomendado
Test and Measurement Instruments
Oscilloscopes, logic analyzers and signal generators distribute fast reference and trigger clocks between boards inside the instrument. The SN65LVDS100DGK buffers these clocks at rates up to 2 Gbps with only 100 ps maximum part-to-part skew, preserving timing alignment between acquisition channels. Its wide input common-mode range (0V to 4V) accepts trigger inputs from CML serializers or LVPECL oscillators without external level shifting, and the VBB reference simplifies AC-coupled single-ended PECL trigger inputs. Low power versus the MC100EP16 ECL alternative reduces instrument thermal load, and the compact VSSOP-8 package fits dense front-end layouts near connectors.
Recomendado
Medical Imaging Equipment
Ultrasound and digital X-ray front ends move high-rate sample data from analog-front-end chips to processing boards. The SN65LVDS100DGK re-drives LVDS data and clock links at rates up to 2 Gbps, restoring amplitude and edge rates degraded by flexible interconnects and rotating or moving cable assemblies. Operation from -40C to +85C and low power consumption suit enclosed, passively cooled medical housings, while exceeding 2000V HBM ESD tolerance aids manufacturing yield. The 470 ps typical delay is deterministic and easily compensated in the frame timing, and the 25 mV hysteresis prevents spurious samples from ground offsets between the imaging head and main chassis.

Notas de diseño
Supply the SN65LVDS100DGK from a clean 3.3V rail within the 3V to 3.6V range. Decouple with a 0.1uF ceramic capacitor within 2-3 mm of the VCC pin plus a 10uF bulk capacitor per device. At 2-Gbps output transitions the driver draws fast transient currents; shared thin power traces to several repeaters will cause supply droop and output duty-cycle distortion. Route VCC to a solid plane rather than a daisy-chained trace.
Keep the repeater within a few centimeters of the connector or source where signal degradation enters the board - placing it mid-board forfeits most of the regenerated margin. Route the 100-ohm differential pairs with matched intra-pair lengths and a solid ground reference; avoid plane splits under the pairs. Terminate the input according to the source family: DC-couple LVDS/CML with standard 100-ohm termination, and use AC coupling or the VBB reference (1.35V below VCC) for single-ended 3.3V PECL inputs.
Remember the device adds approximately 470 ps typical propagation delay - include it in timing closure for clock trees and sample-locked data links. Do not exceed the 0V to 4V input common-mode range, and never DC-couple a PECL output directly to ground through the 100-ohm LVDS termination without checking PECL bias current. Also confirm which family variant you ordered: SN65LVDS100 includes VBB while SN65LVDT100 does not; substituting the LVDT version breaks single-ended PECL biasing schemes.
