Product details
Overview
VSP1900DBTRG4 from Texas Instruments is a CCD vertical clock driver with electric-shutter support, designed for digital and video camera systems. It integrates eight vertical transfer channels (five 3-state + three 2-state), supports both 2-field and 3-field CCD operation, delivers output voltage levels from –9 V to +15.5 V, and operates with 2.7 V–5.5 V digital supply while consuming only 5.3 mW DC power.
For engineers reviewing the VSP1900DBTRG4 datasheet, VSP1900DBTRG4 pinout, VSP1900DBTRG4 application, or VSP1900DBTRG4 equivalent, key selection considerations include multi-level vertical transfer drive capability (3-level ×5, 2-level ×3, E-shutter ×1), high-voltage rail compatibility (VL = –5 V to –9 V, VH = 11.5 V to 15.5 V), and TSSOP-30 package integration for compact CCD timing subsystems.
Technical Context
The VSP1900DBTRG4 implements dedicated level-shifting circuitry per channel to translate TTL/CMOS input logic into CCD-compatible high-voltage waveforms (VL, VM, VH). Its five 3-state drivers handle vertical transfer clocks V1–V5A/V5B with tri-level switching, while three 2-state drivers manage V2/V4/V6 and SUB outputs for simplified 2-field CCD sequencing.
Input phase control enables precise timing coordination with external CCD timing generators (TG), and internal pull-up on CH#N pins ensures safe high-impedance states during 2-field mode. Power sequencing mandates strict order: VDD → VH/VM → VL at power-on, and reverse at shutdown to prevent latch-up or substrate damage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Supply Range | 2.7 V to 5.5 V - powers digital logic core and input interface; compatible with 3.3 V or 5 V microcontroller systems. |
| VL Supply Range | –5 V to –9 V - provides negative bias for CCD substrate and transfer gate sinking; requires isolated negative regulator. |
| VH Supply Range | 11.5 V to 15.5 V - supplies positive high-voltage swing for vertical transfer clocks; enables full CCD charge transfer efficiency. |
| Output Drive Capability | 450 pF to 1890 pF load with 60 Ω–240 Ω series resistance - matches standard CCD pixel array capacitances without external buffering. |
| DC Power Consumption | 5.3 mW - enables battery-powered portable camera designs with minimal thermal impact and extended runtime. |
| Propagation Delay | 15 ns to 100 ns - ensures sub-microsecond timing alignment across all eight vertical clock outputs for low-noise image capture. |
| Output Noise Voltage | ±2 V peak-to-peak - specified under loaded conditions; critical for minimizing vertical smear and fixed-pattern noise in CCD readout. |
Pinout & Package
TSSOP-30 (DBT) package: 30-pin plastic small-outline, 4.4 mm width, 1.2 mm max height, JEDEC MO-153 compliant, surface-mountable with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 15, 29, 30) | Power Ground Reference | Four dedicated ground pins minimize ground bounce across high-current switching outputs and ensure stable level shifter reference. |
| SUBN / SUB (Pins 2 / 28) | CCD Substrate Clock Input / Output | Drives CCD substrate bias with programmable timing; SUBN accepts logic-level input, SUB delivers high-voltage swing (VL to VH). |
| V1N–V6N, V3AN/V3BN, V5AN/V5BN (Pins 3–5, 7, 10, 12–13, 16) | Vertical Transfer Clock Inputs | Eight logic-level inputs synchronized to external TG; each maps to corresponding output (V1–V6, V3A/V3B, V5A/V5B) via dedicated level shifter. |
| V1–V6, V3A/V3B, V5A/V5B (Pins 19–27) | High-Voltage Vertical Clock Outputs | Eight CMOS-compatible outputs delivering –9 V to +15.5 V swing; V1/V3A/V3B/V5A/V5B are 3-state; V2/V4/V6/SUB are 2-state. |
| DVDD (Pin 6), VL (Pin 18), VH (Pin 23) | Power Supply Inputs | DVDD powers digital logic; VL sets negative rail; VH sets positive rail - independent regulation required for clean CCD timing. |
| CH1N–CH5N (Pins 8–9, 11, 14, 17) | Read-Out Clock Inputs | Five logic-level inputs for horizontal readout timing; internally pulled up to avoid floating states during 2-field operation. |
Key Features
| Feature | Design Value |
|---|---|
| Eight-channel vertical clock generation | Integrates five 3-state and three 2-state drivers in one IC, eliminating discrete level shifters and reducing BOM count by ≥7 components. |
| Multi-field CCD support | Configurable for both 2-field and 3-field interlace modes via input state mapping - no hardware change needed between camera generations. |
| Electric-shutter (E-Shutter) channel | Dedicated 2-level driver (V2N/V2) enables precise exposure control without modifying main vertical timing sequence. |
| Low-power digital core | 5.3 mW DC consumption allows direct integration into power-constrained modules like camcorder viewfinders or action cameras. |
| Robust high-voltage output stage | Rated for 450–1890 pF loads with 60–240 Ω series resistance - matches real-world CCD parasitics without external tuning. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CCD vertical driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDA9980 | Single 3.3 V supply; integrated PLL; no negative VL rail; outputs limited to 0–12 V swing. | Designed for HDMI display timing, not CCD charge transfer; lacks E-shutter channel and substrate clock support. | Select only for non-CCD video timing; incompatible with CCD bias requirements of VSP1900DBTRG4. |
| VSP2267 | Complementary device: CCD timing generator (TG) that drives VSP1900DBTRG4 inputs; not a driver itself. | Provides clock synthesis and sequencing logic upstream of VSP1900DBTRG4; requires co-design with this driver. | Use as companion IC - VSP2267 generates timing signals fed into VSP1900DBTRG4 inputs; not a functional replacement. |
Compared with TDA9980 and VSP2267, the VSP1900DBTRG4 uniquely combines negative/positive high-voltage rail support, eight-channel vertical clock drive, and electric-shutter capability in a single TSSOP-30 package - making it irreplaceable for CCD-based imaging where substrate bias and multi-level transfer control are mandatory.

FAQ
What is the primary function of the VSP1900DBTRG4 in a CCD imaging system?
The VSP1900DBTRG4 serves as a dedicated vertical clock driver that translates low-voltage logic inputs from a timing generator into high-voltage, multi-level waveforms required to control charge transfer in CCD sensors. It directly drives vertical transfer gates (V1–V6, V3A/V3B, V5A/V5B) and substrate bias (SUB), enabling both 2-field and 3-field interlace operation while integrating electric-shutter functionality - a role no general-purpose driver IC fulfills.
Does the VSP1900DBTRG4 require external level-shifting circuitry?
No, the VSP1900DBTRG4 integrates on-die level shifters for all eight output channels, eliminating the need for external MOSFETs or discrete level translators. Each input (e.g., V1N, V3AN) connects directly to a timing generator, and the IC internally converts logic-level signals into the required –9 V to +15.5 V output swing using dedicated VL, VM, and VH rails - a core design feature confirmed in the functional block diagram and electrical specifications of the VSP1900DBTRG4.
What are the power supply sequencing requirements for reliable operation of the VSP1900DBTRG4?
The VSP1900DBTRG4 mandates strict power-on and power-off sequencing: during startup, VDD must be applied first, followed by VH and VM, then VL; during shutdown, VL must be removed first, then VH and VM, and finally VDD. This prevents latch-up and substrate damage in connected CCDs. These requirements are explicitly defined in the "Operation" section of the VSP1900DBTRG4 datasheet and are non-negotiable for long-term reliability.
Can the VSP1900DBTRG4 drive both 2-field and 3-field CCDs without hardware modification?
Yes, the VSP1900DBTRG4 supports both 2-field and 3-field CCD operation through configurable input logic states - no PCB changes or external jumpers are needed. In 2-field mode, one of the five 3-state drivers is repurposed as a 2-state driver, and internal pull-ups on CH#N pins prevent unintended VH-level outputs. This dual-mode capability is verified in the truth table and functional description of the VSP1900DBTRG4.
What is the maximum capacitive load the VSP1900DBTRG4 can drive reliably?
The VSP1900DBTRG4 is characterized to drive capacitive loads from 450 pF to 1890 pF when paired with series resistors ranging from 60 Ω to 240 Ω - values aligned with standard CCD pixel array parasitics shown in the official loading diagram. This range covers common interline and full-frame CCDs used in digital cameras and industrial sensors, and performance remains stable across the full operating temperature range (–25°C to +85°C) per the VSP1900DBTRG4 datasheet.
