ISL55112: High-Speed Dual Precision CCD Driver

The ISL55112 is a high-speed CCD array driver comprising 2 Horizontal drivers with high current output drive and 2 ancillary signal drivers with lower current output drive.

The devices can be used in pairs to drive and control two halves of a high pixel count CCD array as used in high end Digital Cameras or Camcorders. The device has a largely symmetric pinout about a center axis to facilitate the placement of the devices on either side of a large CCD array with minimal signal routing disruption.

The ISL55112 can accommodate split asymmetric voltage supplies up to 8V total for each of the 4 drivers and has significant flexibility in the selection of these supply voltages within this range. All 4 drivers have their own High and Low level supply lines to minimize
interference between drivers caused by shared current paths.

Special circuitry for the high current drivers is included to ensure the highest degree of stability of the driver output resistance over varying supply voltage, temperature and
semiconductor process variations, resulting in highly consistent, predictable waveform crossover points.

The ISL55112 can drive high capacitance loads at pixel clock rates exceeding 30MHz with low propagation delays, and skews between channels of better than ±500ps.

The ISL55112 is available in 24 Ld exposed pad TQFN package and is specified for operation over the full -40℃ to +85℃ temperature range.
