Texas Instruments VSP2210Y

Overview

VSP2210Y from Burr-Brown Corporation is a complete mixed-signal CCD signal processor IC for digital cameras, integrating correlated double sampling (CDS), programmable gain amplifier (PGA) with –6 dB to +42 dB range, 10-bit ADC operating up to 20 MHz, 79 dB SNR at 0 dB gain, and dual on-chip 8-bit DACs - deployed in optical black level clamping and CCD VSUB control.

For engineers reviewing the VSP2210Y datasheet, VSP2210Y pinout, VSP2210Y application, or VSP2210Y equivalent, this page delivers verified electrical specifications, LQFP-48 package mapping, CDS timing constraints, PGA gain linearity behavior, and real-world use cases in digital still and security camera signal chains.

Technical Context

The VSP2210Y implements a fully differential pipelined ADC architecture optimized for low-voltage (2.7–3.6 V) operation and high-speed CCD readout, with fixed 9-cycle data latency in normal mode and 11-cycle latency during preblanking. Its CDS stage uses switched-capacitor topology with independently configurable SHP/SHD polarity via serial interface.

Signal conditioning includes input clamp restoration to 1.5 V CM reference, optical black clamp loop with 0.1 µF external COB capacitor (40.7 µs time constant), and programmable OB clamp level (0–60 LSB in 4-bit register). All analog references (REFP, REFN, CM, BYPP2, BYP, BYPM) require dedicated ceramic bypassing and must not be shared with other circuitry.

FAQ

What is the function of the COB pin on the VSP2210Y?

The COB pin on the VSP2210Y serves as the output of the optical black (OB) clamp loop's control DAC. It drives an external 0.1 µF capacitor to set the loop time constant (40.7 µs) and slew rate (1530 V/s), enabling auto-calibration of the black reference level using CCD optical black pixels. This ensures stable pedestal establishment critical for consistent image black point across temperature and illumination changes in the VSP2210Y.

Does the VSP2210Y support both Active HIGH and Active LOW timing pulse polarities?

Yes, the VSP2210Y supports configurable polarity for SHP, SHD, CLPOB, and CLPDM via its 3-wire serial interface - P[2:0] register bits select Active HIGH or Active LOW for each signal. The default after RESET is Active LOW, but the device powers up with unknown polarity states, requiring explicit initialization through the serial interface before operation. This flexibility allows the VSP2210Y to interface with diverse CCD timing generators.

What is the purpose of the PBLK pin on the VSP2210Y?

The PBLK (Preblanking) pin on the VSP2210Y disables the CCDIN input path during CCD blanking intervals to prevent large transient signals from saturating the CDS and ADC stages. When PBLK is asserted LOW, the VSP2210Y outputs all zeros after 11 clock cycles of ADCCK, avoiding extended recovery delays. This feature protects signal integrity in high-slew CCD outputs and is essential for maintaining clean image start-of-frame in the VSP2210Y.

How does the VSP2210Y handle black level clamping when dummy pixels are unavailable?

When dummy pixels are unavailable, the VSP2210Y allows CLPOB (optical black clamp pulse) to substitute for CLPDM (dummy pixel clamp pulse) by activating both CLPOB and SHP simultaneously during optical black pixel intervals. This triggers the input clamp function using the OB pixels instead of dummy pixels, ensuring DC restoration and proper CDS biasing. The VSP2210Y's register-controlled polarity and timing flexibility make this substitution reliable without hardware modification.

What are the absolute maximum ratings for the VSP2210Y's power supplies?

The VSP2210Y has absolute maximum supply ratings of +4.0 V for VCC and DRVDD, with supply voltage differences limited to ±0.1 V between VCC pins and ground differences limited to ±0.1 V between GNDA and DRVGND. Exceeding these ratings may cause permanent damage. The recommended operating range is 2.7 V to 3.6 V, and the device draws 97 mW typical at 3.0 V - making adherence to these limits critical for long-term reliability of the VSP2210Y.
