Product details
Overview
VSP2230Y from Texas Instruments is a mixed-signal CCD signal processor IC for digital cameras, integrating correlated double sampling (CDS), programmable gain amplifier (−6 dB to 42 dB), 10-bit ADC (up to 36 MHz), 76-dB SNR, and black level clamping - deployed in optical imaging front-ends of portable digital still cameras.
For engineers reviewing the VSP2230Y datasheet, VSP2230Y pinout, VSP2230Y application, or VSP2230Y equivalent, key selection considerations include its single 2.7–3.6 V supply operation, LQFP-48 package compatibility with VSP2260Y, standby power (6 mW), and absence of missing codes in digitized video output.
Technical Context
The VSP2230Y implements analog signal conditioning specifically for CCD image sensors: CDS removes reset noise and kTC noise before PGA amplification; gain control is digitally programmable and linear in dB; black level clamping uses optical black (OB) pixels and supports fast recovery after gain changes.
Its timing architecture includes dedicated SHP/SHD/CLPDM control inputs synchronized to CCD pixel clocking, while the 10-bit parallel digital output (B0–B9) latches on ADCCK, supporting up to 36-MHz conversion without missing codes under specified operating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ADC Resolution | 10-bit, guaranteed no missing codes - ensures monotonicity and full code coverage for accurate pixel intensity mapping. |
| Max Conversion Rate | 36 MHz - supports high-frame-rate digital still camera operation with minimal latency per line. |
| PGA Gain Range | −6 dB to 42 dB - enables dynamic adaptation to varying scene illumination without external gain stages. |
| Signal-to-Noise Ratio | 76 dB - delivers high-fidelity analog signal conditioning prior to digitization in low-light imaging. |
| Supply Voltage | 2.7 V to 3.6 V - compatible with single-cell Li-ion or regulated 3.3-V systems in portable imaging devices. |
| Power Consumption | 120 mW typical at 3.0 V - enables thermal-constrained designs in compact digital camera modules. |
| Operating Temperature | 0°C to +85°C - validated for commercial-grade embedded imaging applications including consumer camcorders. |
Pinout & Package
The VSP2230Y is housed in a 48-pin LQFP (PT) package with exposed thermal pad, RoHS-compliant green finish (CU NIPDAU), and JEDEC Level-1 moisture sensitivity rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CCDIN | CCD Analog Input | Primary differential input for CCD sensor video output; accepts preblanked analog signal with DC offset. |
| SHP / SHD | Sampling Control Inputs | SHP initiates CDS sample phase; SHD controls hold phase - together define correlated double sampling window timing. |
| CLPDM | Clamp Enable | Activates optical black (OB) pixel-based black level clamping during preblanking interval. |
| B0–B9 | Digital Output Bus | 10-bit parallel CMOS outputs latched on ADCCK edge; directly interfaces FPGA or image processor data bus. |
| ADCCK | ADC Clock Input | Drives internal ADC sampling; max 36 MHz frequency defines upper limit of pixel readout rate. |
| RESET | Global Reset | Asynchronous active-low reset for internal logic and analog blocks; required before initialization sequence. |
| DRVDD / DRVGND | Digital I/O Supply | Separate 3.3-V domain for digital interface pins - isolates noise-sensitive analog section (VCC/GNDA). |
| REFP / REFN / BYPM / BYPP2 / CPLOB / COB | Analog Reference & Bypass | Support precision reference generation and noise filtering for CDS/PGA/ADC; BYPM/BYPP2 stabilize internal bias voltages. |
Key Features
| Feature | Design Value |
|---|---|
| Correlated Double Sampling (CDS) | Removes reset noise and kTC noise from CCD output - essential for clean pixel-level signal extraction in low-noise imaging. |
| Optical Black Level Clamping | Uses OB pixels during preblanking to establish accurate black reference - maintains consistent black level across gain changes and temperature drift. |
| Digital PGA Control | Linear-in-dB gain adjustment (−6 dB to 42 dB) via serial interface - eliminates need for external DACs or analog gain switches. |
| No Missing Codes | Guaranteed monotonic 10-bit transfer function - prevents intensity discontinuities in digitized image data critical for color accuracy. |
| Low-Power Standby Mode | 6 mW consumption - enables rapid wake-up between frame captures in battery-powered digital cameras. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CCD signal processing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSP2260Y | 10-bit, 20-MHz max conversion rate; identical pinout and functional block diagram but lower speed grade. | Targeted at cost-sensitive or lower-resolution digital cameras where 36-MHz bandwidth is unnecessary. | Select VSP2260Y when system frame rate requirements are ≤20 MHz and BOM cost optimization is prioritized. |
| AD9826 | 16-bit, 20-MHz CCD signal processor from Analog Devices; higher resolution but no integrated black level clamping or CDS control logic. | Used in scientific and industrial imaging where bit depth outweighs integration convenience. | Choose AD9826 only if 16-bit dynamic range is mandatory and external clamping/CDS circuitry can be accommodated. |
Compared with VSP2260Y and AD9826, the VSP2230Y uniquely balances 36-MHz throughput, integrated CDS+clamping, and single-supply portability - making it optimal for mid-tier digital still cameras needing both speed and analog integration.

FAQ
What is the primary function of the VSP2230Y in a digital camera system?
The VSP2230Y serves as the complete analog signal processor and ADC for CCD image sensors. It performs correlated double sampling to remove reset noise, applies digitally controlled gain (−6 dB to 42 dB), clamps black level using optical black pixels, and outputs 10-bit digitized video at up to 36 MHz. Its integration eliminates discrete analog stages in the VSP2230Y signal path.
Does the VSP2230Y require multiple supply voltages?
No, the VSP2230Y operates from a single 2.7-V to 3.6-V supply, with separate DRVDD/DRVGND pins for digital I/O and VCC/GNDA for analog sections. This dual-domain layout minimizes noise coupling while maintaining single-supply convenience - a key design feature confirmed in the SLAS319 datasheet for the VSP2230Y.
Is the VSP2230Y pin-to-pin compatible with other TI CCD processors?
Yes, the VSP2230Y is explicitly documented as pin-to-pin compatible with the VSP2260Y, sharing identical 48-pin LQFP (PT) packaging and register-mapped serial interface. This compatibility allows direct substitution in existing layouts where higher-speed operation (up to 36 MHz vs. 20 MHz) is needed without PCB revision for the VSP2230Y.
What does "Not Recommended For New Designs" mean for the VSP2230Y?
"Not Recommended For New Designs" (NRND) indicates TI no longer promotes the VSP2230Y for newly initiated projects due to newer alternatives, though it remains in production for existing customers. Aetrix Electronics supports legacy VSP2230Y supply with traceable sourcing and lifecycle coordination - ensuring continuity for ongoing manufacturing of systems already designed around the VSP2230Y.
How does the VSP2230Y handle black level stability during gain changes?
The VSP2230Y uses optical black (OB) pixel sampling and dedicated CLPDM control to perform fast black level clamping during preblanking intervals. Its architecture ensures black level recovery within one line period after PGA gain adjustment - a behavior verified in characterization data and explicitly cited in the VSP2230Y datasheet description.
