Product details
Overview
VSP1000DSFR from Texas Instruments is a high-speed, low-noise, unity-gain CCD sensor buffer IC with 210 MHz bandwidth, adjustable active load current (up to 4 mA), and adjustable output drive strength. It operates from 10–16 V supply, consumes only 20 mW at 2 mA ICC, and interfaces directly between CCD outputs and analog front-ends in precision imaging systems.
For engineers reviewing the VSP1000DSFR datasheet, VSP1000DSFR pinout, VSP1000DSFR application, or VSP1000DSFR equivalent, this page delivers verified electrical parameters, thermal metrics, QFN-6 package layout guidance, and real-world CCD interface design constraints - all confirmed from TI's SBES023A datasheet and official ordering documentation.
Technical Context
The VSP1000DSFR implements a fast-settling, unity-gain voltage buffer with fully differential input loading control via ISF and output drive tuning via IDRV. Its internal architecture supports independent adjustment of input sink current (IIN) and output drive current (IDRV) using external resistors RISF and RIDRV, enabling precise matching to diverse CCD sensor output characteristics.
It features rail-to-rail input voltage range (1.5 V to 10.5 V at VCC = 13 V), sub-6 ns rise/fall times, and 1.28 ns I/O delay. Thermal design is supported by θJA = 333.2°C/W and θJB = 239°C/W for board-level heat dissipation in compact imaging modules.
Key Specifications

|---|---|
| 3-dB Bandwidth | 210 MHz at 2 mA drive current - enables high-resolution, high-frame-rate CCD readout without signal distortion |
| Rise/Fall Time | 5 ns / 6 ns - ensures minimal timing skew in fast transient CCD pixel output signals | I/O Delay | 1.28 ns - preserves critical timing alignment between sensor output and AFE sampling clock |
| Supply Current | 2 mA typical at VCC = 13 V - achieves ultra-low power operation while maintaining 210 MHz bandwidth |
| Input Voltage Range | 1.5 V to 10.5 V at VCC = 13 V - accommodates wide dynamic range CCD output swing |
| Operating Temp | 0°C to +85°C - qualified for industrial and embedded imaging environments |

Pinout & Package
The VSP1000DSFR is housed in a 1-mm × 1-mm × 0.35-mm ultra-thin X2SON (QFN-6) package with exposed thermal pad, optimized for space-constrained CCD camera modules and low-profile PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Analog input | Connects directly to CCD sensor output; sinks adjustable current set by RISF on ISF pin |
| GND (Pin 2) | Ground reference | Common return path for input sink current and output drive current; must be low-impedance |
| OUT (Pin 3) | Analog output | Drives AFE input with adjustable strength; bandwidth scales with IDRV current |
| IDRV (Pin 4) | Drive strength control | Resistor-connected analog input that sets output drive current and total quiescent current |
| VCC (Pin 5) | Positive supply | 10–16 V power input; requires local 0.1-µF decoupling to GND |
| ISF (Pin 6) | Sink current control | Resistor-connected analog input that sets input load current drawn from CCD output |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable input load current | Configurable from ~2 mA to 4 mA via external RISF, enabling compatibility with multiple CCD sensor families |
| Bandwidth tuning | 170–260 MHz range selectable via RIDRV, allowing trade-off between speed and power consumption |
| Ultra-small footprint | 1 mm × 1 mm X2SON package saves >70% board area vs. legacy SOIC-8 buffers in camera module designs |
| Low-power operation | 20 mW typical at 210 MHz - reduces thermal load and extends battery life in portable imaging devices |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar CCD buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4302DR | Fixed 1.5-GHz bandwidth, no adjustable load current; higher 35-mW power draw | Requires external current source for CCD loading; less flexible for multi-sensor platforms | Select when maximum bandwidth is required and CCD loading is handled separately |
| VSP1001DSFR | Same pinout and package; adds integrated 2.5-V reference for biasing; 180-MHz bandwidth | Designed for CCD+AFE pairs requiring internal reference; lower bandwidth than VSP1000DSFR | Select when reference voltage generation is needed and 210-MHz bandwidth is not mandatory |
Compared with THS4302DR and VSP1001DSFR, the VSP1000DSFR uniquely balances tunable loading, 210-MHz bandwidth, and 20-mW power in a 1-mm² footprint - making it optimal for cost-sensitive, space-constrained CCD systems where both flexibility and performance matter.

FAQ
What is the recommended decoupling capacitor for VSP1000DSFR?
A 0.1-µF ceramic capacitor must be placed between VCC (Pin 5) and GND (Pin 2), located as close as possible to the device. This minimizes supply noise coupling into the sensitive analog signal path and ensures stable operation at 210 MHz. The VSP1000DSFR datasheet explicitly specifies this value and placement requirement in the Layout Guidelines section.
Can VSP1000DSFR drive a 50-Ω transmission line directly?
No, the VSP1000DSFR is not designed for direct 50-Ω line driving. Its output is optimized for capacitive loads up to 22 pF and moderate-impedance AFE inputs. Driving 50-Ω lines would require external termination and may degrade bandwidth and settling behavior. For such applications, TI recommends pairing VSP1000DSFR with a dedicated line driver like THS3201.
What is the maximum input voltage range for VSP1000DSFR at 13-V supply?
At VCC = 13 V, the VSP1000DSFR supports an input voltage range of 1.5 V to 10.5 V, as specified in the Electrical Characteristics table. This 9-V span accommodates typical CCD output swings while maintaining linear operation and avoiding clipping or saturation in the buffer stage.
How does the ISF pin adjust input load current in VSP1000DSFR?
The ISF pin (Pin 6) accepts an external resistor RISF to ground, setting the current sunk from the IN pin (Pin 1). Per Equation 1 in the datasheet, IIN ≈ 26 × IDRV, where IDRV is derived from IDRV settings. Typical configurations yield 2–4 mA input load, essential for proper CCD biasing and charge transfer efficiency in VSP1000DSFR-based designs.
Is VSP1000DSFR RoHS compliant and what is its MSL rating?
Yes, VSP1000DSFR is RoHS compliant (lead-free, NIPDAU finish) and carries an MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH), per TI's Package Option Addendum. This allows standard SMT assembly without baking or special handling - a key advantage for high-volume camera module manufacturing using VSP1000DSFR.
