On screen display ICs added to range

Sequoia has launched two new models in the popular Sanyo LC7XX family on-screen display ICs to overlay and personalise text such as day/date, time of day, user ID or titles on analogue video sources.

Sequoia has launched two new models into the popular Sanyo LC7XX family of on-screen display ICs to overlay and personalise text such as day/date, time of day, user ID or titles on analogue video sources from applications such as security cameras or critical care monitoring.

Displaying up to 12 lines of 24 characters, the family features a selection of fixed character font sets, including a user defined set.

The compact LC74732W CMOS IC displays 16 x 16-dot characters on a TV screen under the control of a microcontroller.

The IC supports up to 512 characters internally, although up to 8192 characters of user defined fonts can be imported using an external ROM.

This flexibility of character support is particularly useful for companies exporting to countries such as Japan.

The LC74732W measures just 12 x 12 x 1.7mm.

In addition, four sizes of character can be selected in 128 display start positions and other features include blinking (two types with periods of 1.0 and 0.5 seconds), reverse video, reversed blinking and character outlining.

The whole font area can be blanked in line units with four options for a customised solution.

The entry level LC74781 features 12 x18 dot characters in three size settings and a 128 character set.

64 display start position settings with character blanked data output are available in the 10.5 x 15.3 x 2.15mm package.

The LC7XX Family features a built-in sync separator circuit and is suitable for Compound NTSC, PAL, PAL-N and PAL-M video outputs.
