Toshiba Introduces Lens Reduction Type CCD Linear Image Sensor for A3 Multifunction Printers

2021-03-17 | Return

TOKYO—Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched “TCD2726DG,” a lens reduction type CCD linear image sensor that achieves high-speed scanning for A3

multifunction printers. Shipments of engineering samples[1] start today.

There is growing demand for A3 multifunction printers with higher scanning speeds. TCD2726DG meets the demand by improving the performance with a faster operating clock rate: a 100MHZ (50MHz x 2ch) data rate, against the 70MHz (35MHz x 2ch) data rate of Toshiba’s current sensor[2].

To prevent increased electromagnetic interference (EMI), a negative side effect of a faster clock rate, the new sensor incorporates a timing generator circuit and has a lower CCD driver pin count. This reduces EMI- and timing-adjustment work for customers, and the number of peripheral parts, contributing to easier system development.

[1] The samples are for functional evaluation. Their specifications may differ from those for mass production.
