Product details
Overview
TCD1209DG(8Z,W) from Toshiba Electronic Devices & Storage Corporation is a 2048-element CCD linear image sensor with 14 μm × 14 μm photodiodes, 5 V two-phase clock operation, 12 V power supply, and 22-pin CERDIP package-designed for high-resolution document scanning across B4-size paper at 8 lines/mm.
For engineers reviewing the TCD1209DG(8Z,W) datasheet, TCD1209DG(8Z,W) pinout, TCD1209DG(8Z,W) application, or TCD1209DG(8Z,W) equivalent, key selection criteria include dark signal voltage (≤2.5 mV), dynamic range (2000), transfer efficiency (92–98%), PRNU (≤10%), and timing-critical pulse width constraints (e.g., SH pulse width 1000–1500 ns).
Technical Context
The TCD1209DG(8Z,W) implements a charge-coupled architecture with dedicated transfer clocks (φ1, φ2, φ2B), reset (RS), clamp (CP), and shift gate (SH) control signals to serially read out integrated photodiode charge. Its PN photodiode array delivers high sensitivity (31 V/(lx·s) typ.) and low dark current under 25°C operation.
Operation requires precise 5 V logic-level clock pulses synchronized with 12 V analog supply (VOD), where timing margins are critical: φ1/φ2 cross-point delay ≤17 ns, RS pulse width 10–100 ns, and video data delay t11 = 15 ns typ. All voltages referenced to SS (ground) pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Image elements | 2048 pixels in single row-enables full-width B4 paper coverage at 8 lines/mm resolution |
| Pixel pitch | 14 μm center-to-center-defines optical sampling density and minimum resolvable feature size |
| Saturation exposure | 0.06 lx·s typ.-determines maximum incident light before pixel saturation in daylight fluorescent illumination |
| Dynamic range | 2000 typ.-ratio of saturation output (2.0 V) to dark signal (1.0 mV avg.), enabling wide scene luminance capture |
| Total transfer efficiency | 92–98%-quantifies charge retention during serial register transfer; impacts SNR and linearity |
| Random noise | 0.6 mV σ typ.-measured as ΔV standard deviation between adjacent dark pixels, limiting low-light detectability |
| DC output signal voltage | 5.5 V typ.-baseline video output level referenced to SS, requiring compatible ADC input range |
Pinout & Package
Package: 22-pin ceramic dual in-line package (CERDIP), WDIP22-G-400-2.54H footprint, glass window over active die area, rated for −25°C to +60°C operating temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OS | Video output signal-high-impedance analog voltage proportional to integrated photodiode charge |
| 2 | SS | Signal ground reference-common return for all analog and digital supplies and clocks |
| 3 | OD | Analog power supply-12 V supply for CCD vertical/horizontal registers and output amplifier |
| 5 | φ1 | Transfer clock phase 1-drives charge transfer from photodiodes into horizontal register |
| 6 | φ2 | Transfer clock phase 2-completes pixel-to-pixel charge transfer in horizontal register |
| 18 | RS | Reset gate-clears floating diffusion node prior to signal sampling; 10–100 ns pulse width required |
| 21 | CP | Clamp gate-establishes DC baseline for OS signal during clamping interval; timing-critical relative to φ2B |
| 22 | SH | Shift gate-controls horizontal charge transfer timing; 1000–1500 ns pulse width ensures full pixel shift |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear CCD image sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCD1208DG | 2048-element variant with identical pinout and 14 μm pitch but lower sensitivity (28 V/(lx·s) typ.) and higher dark signal (1.5 mV typ.) | Acceptable for cost-sensitive scanners where ambient light is controlled; not recommended for low-light barcode reading | Select TCD1208DG only if system-level SNR budget allows ≥3 dB degradation versus TCD1209DG(8Z,W) |
| KAI-02150 | 2152-pixel CMOS linear sensor with on-chip ADC, LVDS output, and 3.3 V operation-no external clocks or 12 V supply required | Enables simplified digital interface but requires redesign of timing controller and power delivery; incompatible with analog video chain | Choose KAI-02150 only when migrating to fully digital architecture and accepting PCB layout changes |
Compared with TCD1209DG(8Z,W), TCD1208DG offers identical mechanical and electrical compatibility at reduced optical performance, while KAI-02150 replaces analog CCD operation with integrated digital conversion-requiring new firmware, clocking, and power design but eliminating analog noise sensitivity.

FAQ
What is the operating power supply requirement for the TCD1209DG(8Z,W)?
The TCD1209DG(8Z,W) requires a 12 V analog power supply (VOD) for its CCD registers and output amplifier, and 5 V logic-level pulses for φ1, φ2, SH, RS, and CP clocks. Per datasheet Rev.2.4, VOD must be maintained between 11.4 V and 13.0 V for guaranteed performance; exceeding 15.0 V risks permanent damage. The TCD1209DG(8Z,W) draws up to 400 mW under typical conditions.
Does the TCD1209DG(8Z,W) include on-chip analog-to-digital conversion?
No, the TCD1209DG(8Z,W) is an analog-output CCD sensor: its OS pin delivers a continuous voltage waveform proportional to integrated photodiode charge, requiring external amplification and digitization. It contains no ADC, memory, or digital interface logic. System designers must provide a separate 12-bit or higher ADC with sampling aligned to the 15 ns video data delay (t11) specified in the TCD1209DG(8Z,W) timing chart.
What is the significance of the "8Z,W" suffix in TCD1209DG(8Z,W)?
The "8Z,W" suffix denotes Toshiba's internal package and screening variant: "8Z" specifies the WDIP22-G-400-2.54H 22-pin CERDIP package with 2.54 mm lead pitch and glass window, while "W" indicates compliance with Toshiba's standard industrial-grade reliability screening (including extended temperature validation and humidity testing). This suffix distinguishes it from bare-die or alternate-package versions of the same core die.
How does dark signal non-uniformity (DSNU) affect TCD1209DG(8Z,W) performance in scanning applications?
DSNU in the TCD1209DG(8Z,W) is specified at ≤2.5 mV peak-to-peak, representing pixel-to-pixel variation in thermal dark current. In scanning systems, uncorrected DSNU manifests as fixed-pattern noise-visible as faint horizontal bands in uniform-field captures. System-level correction requires per-pixel offset calibration using dark-frame subtraction; the TCD1209DG(8Z,W)'s low 1.0 mV typical dark signal simplifies this calibration and improves stability over temperature.
Can the TCD1209DG(8Z,W) operate at clock frequencies above 1 MHz?
Yes-the TCD1209DG(8Z,W) supports clock frequencies up to 20 MHz per the datasheet, though optimal optical performance (e.g., PRNU, dynamic range) is characterized at 1 MHz. At higher frequencies, transfer efficiency may decrease below 92%, and random noise may rise due to incomplete charge transfer. For applications demanding maximum SNR-such as high-accuracy OCR-the TCD1209DG(8Z,W) should be operated at or near its 1 MHz typ. clock frequency.
