description  
The TC253SPD device is a frame-transfer, CCD image sensor designed for use in black and white NTSC TV,  
computer, and special-purpose applications that require high sensitivity, low noise, and small size.  
The TC253SPD sensor is a new device of the IMPACTRONt family of very low noise, high sensitivity image  
sensors that multiply charge directly in the charge domain before conversion to voltage. The charge carrier  
multiplication (CCM) is achieved by using a low-noise, single-carrier, impact ionization process that occurs  
during repeated carrier transfers through high field regions. Applying multiplication pulses to specially designed  
gates activates the CCM. The amount of multiplication is adjustable, depending on the amplitude of the  
multiplication pulses. The device function resembles the function of image intensifiers implemented in solid  
state.  
This MOS device contains limited built-in gate protection. During storage or handling, the device leads should be shorted together  
or the device should be placed in conductive foam. In a circuit, unused inputs should always be connected to V . Under no  
SS  
circumstances should pin voltages exceed absolute maximum ratings. Avoid shorting OUT to V  
during operation to prevent  
SS  
damage to the amplifier. The device can also be damaged if the output terminals are reverse-biased and an excessive current is  
allowed to flow. Specific guidelines for handling devices of this type are contained in the publication Guidelines for Handling  
Electrostatic-Discharge-Sensitive (ESDS) Devices and Assemblies available from Texas Instruments.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

description (continued)  
The image-sensing area of the TC253SPD sensor is configured into 500 lines with 680 pixels in each line.  
Twenty-two pixels are reserved in each line for dark reference. The blooming protection is based on an  
advanced lateral overflow drain concept that does not reduce NIR response. The sensor can be operated in  
the interlaced or progressive scan modes and can capture full 340,000 pixels in one image field. The frame  
transfer from the image-sensing area to the memory area is accomplished at a very high rate that minimizes  
image smear. The electronic exposure control is achieved by clearing unwanted charge from the image area  
using a short positive pulse applied to the antiblooming drain. This pulse marks the beginning of the integration  
time, which can be arbitrarily shortened from its nominal length. After charge is integrated and stored in the  
memory it is available for readout in the next cycle. This is accomplished using a unique serial register design  
that includes special charge multiplication pixels.  
The TC253SPD sensor is built using TI-proprietary advanced split-gate virtual-phase CCD (SGVPCCD)  
technology, which provides devices with wide spectral response, ranging from DUV to NIR, high quantum  
efficiency (QE), low dark current, and high response uniformity. The TC253SPD sensor is characterized over  
an operating free-air temperature range of T = 10°C to 45°C.

detailed description  
The TC253SPD sensor consists of four basic functional blocks: the image-sensing area, the image storage  
area, the serial register, and the charge multiplier. The location of each of these blocks is identified in the  
functional block diagram.  
image-sensing and storage areas  
Figure 1 and Figure 2 show cross sections with potential-well diagrams and top views of the pixels in the  
image-sensing and storage areas. As light enters silicon in the image-sensing area, electrons are generated  
and collected in potential wells of the pixels. Applying a suitable dc bias to the antiblooming drain provides  
blooming protection. Electrons that exceed a specified level, determined by the ODB bias, are drained away  
from the pixels. If it is necessary to remove all previously accumulated charge from the wells, a short positive  
pulse must be applied to the drain. This marks the beginning of the new integration period. After the integration  
cycle is completed, charge is quickly transferred into the memory where it waits for readout. The lines can be  
read out from the memory in a sequential order to implement progressive scan, or two lines can be summed  
together to implement the pseudo-interlace scan.  
Twenty-two columns at the left edge of the image-sensing area are shielded from incident light. These pixels  
provide the dark reference used in subsequent video-processing circuits to restore the video black level. An  
additional four dark lines located between the image-sensing area and the image storage area were added for  
isolation.

advanced lateral overflow drain  
The advanced lateral overflow drain structure is shared by two neighboring pixels in each line. Varying the dc  
bias of the antiblooming drain can control the blooming protection level and trade it for well capacity. Applying  
a pulse (approximately 10 V above the nominal level for a minimum of 1 µs) to the drain removes all charge from  
the pixels. This feature permits a precise control of the integration time on a frame-by-frame basis. The  
single-pulse clearing capability also reduces smear by eliminating accumulated charge in the pixels before the  
start of the integration period (single-sided smear). The application of a negative 1-V pulse to the antiblooming  
drain during the parallel transfer is recommended. This pulse prevents creation of undesirable artifacts caused  
by the on-chip crosstalk between the image area gate clock lines and the antiblooming drain bias lines.  
serial register and charge multiplier  
The serial register is used to transport charge stored in the pixels of the memory to the output amplifier. However,  
the TC253SPD device has a serial register with twice the standard length. The first half has a conventional  
design that interfaces with the memory and the clearing drain as it would in any other CCD sensor (for example  
the TC237 sensor). The second half, however, is unique and includes 400 charge multiplication stages with a  
number of dummy pixels that are needed to transport charge between the active register blocks and the output  
amplifier. Charge is multiplied as it progresses from stage to stage in the multiplier toward the charge detection  
node. The charge multiplication level depends on the amplitude of multiplication pulses (approximately 11 V ~  
17 V) applied to the multiplication gates. Due to the double length of the registers, the first line in the field or frame  
scan does not contain valid data and must be discarded.  
readout and video processing  
The last element of the charge readout and detection chain is the charge detection node. Charge detection  
nodes use standard floating diffusion (FD) concepts followed by dual-stage source followers as buffer  
amplifiers. The reset gate is internally connected to SRG1. This connection results in a simultaneous FD reset  
when the SRG1 gate is clocked high. To achieve the ultimate sensor performance, it is necessary to eliminate  
the detection node kTC noise using CDS processing techniques. The IMPACTRONt devices can detect single  
photons when cooling or when sufficiently short integration times are used.

NOTES: 2. Excess noise factor F is defined as the ratio of noise sigma after multiplication divided by M times the noise sigma before  
multiplication where M is the charge multiplication gain.  
3. Dynamic range is 20 times the logarithm of the mean noise sigma divided by the saturation output signal amplitude.  
4. Charge conversion factor is defined as the ratio of output signal to input number of electrons.  
5. Signal-response delay time is the time between the falling edge of the SRG2 pulse and the output signal valid state.  
6. Charge transfer efficiency is 1 minus the charge loss per transfer in the CCD register. The test is performed in the dark using either  
electrical or optical input.  
7. Rejection ratio is 20 times the logarithm of the output referenced to the reset level divided by the 1 V of amplitude change of the  
corresponding gate or terminal signal.

NOTES: 8. Light source temperature is 2856°K. The IR filter used is CM500 1 mm thick.  
9. Saturation is the condition in which further increase in exposure does not lead to further increases in output signal.  
10. Zero-input offset is the residual output signal measured from the reset level with no input charge present. This level is not caused  
by the dark current and remains approximately constant, independent of temperature. This level can vary with the amplitude of  
SRG2.  
11. Blooming is the condition in which charge induced by light in one element spills over to the neighboring elements.  
12. Smear is the measure of error signal introduced into the pixels by transferring them through the illuminated region into the memory.  
The illuminated region is 1/10 of the image area height. The value in the table is obtained for the integration time of 16.66 ms and  
3.125 MHz vertical clock transfer frequency.  
13. Dark current depends on temperature and approximately doubles every 8°C. Dark current is also multiplied by the CCM operation.  
The value given in the table is with the multiplier turned off, and it is a calculated value.  
14. Dark signal is actual device output measured in darkness.  
15. Dark signal uniformity is the sigma of difference of two neighboring pixels taken from all the image area pixels.  
16. Dark signal shading is the difference between maximum and minimum of a 5-pixel median taken anywhere in the array.  
17. Column uniformity is obtained by summing all the lines in the array, finding the maximum of the difference of two neighboring columns  
anywhere in the array, and dividing the result by the number of lines.
