High-Speed Dual Precision CCD Driver
ISL55112
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°C
to +85°C temperature range.

1. Add “-T” suffix for tape and reel. Please refer to TB347 for
details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ
special Pb-free material sets; molding compounds/die
attach materials and 100% matte tin plate plus anneal (e3
termination finish, which is RoHS compliant and
compatible with both SnPb and Pb-free soldering
operations). Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the
Pb-free requirements of IPC/JEDEC J STD-020.
