•
Frame Transfer CCD Technology. Contiguous pixels for 100% fill factor. No "dead space"
between pixels.
•
755 (H) X 242 (V) active picture elements per field.
•
Interlaced operation doubles effective vertical resolution; Image format is 755(H) X 484(V)
•
8.5
µ
m (H) X 19.75
µ
m (V) pixel size.
•
On-chip correlated-clamp sample & hold circuits to minimize noise.
•
On-chip shielded pixels provide "dark pixel" level for black level reference.
•
8 mm. image diagonal, compatible with ½ " optics.
•
High sensitivity; unlike Interline Transfer CCDs which have "dead spaces" that lower
sensitivity.
•
Solid state reliability with no image burn-in, residual imaging, image distortion, lag or
microphonics
•
Minimum 100:1 blooming overload ratio (with Interlace on).
•
70 dB sensor dynamic range. Full well >80,000 electrons; Noise equivalent signal <30
electrons (typical 20 electrons)
•
High photo-response uniformity; <5% photo-response-non-uniformity guaranteed (typical
<2%); blemish free sensor.
4.1 TC-245 CCD Functional Details
The TC-245 is a frame transfer charge coupled device (CCD) image sensor designed for use in
single chip B/W NTSC TV applications. The device is intended to replace a 1/2 inch vidicon tube
in applications requiring small size, high reliability and low cost.
