ISL59831

Single Supply Video Driver with Reconstruction Filter and Charge Pump

DATASHEET

The ISL59831 is a single supply video driver with

reconstruction filter and charge pump. It is designed to drive

SDTV displays with luma (Y) or composite video (CV)

signals. It operates on a single supply (3.0V to 3.6V) and

generates its own negative supply (-1.9V) using a regulated

charge pump. Input signal can be AC or DC coupled. When

AC coupled, the sync tip clamp sets the blank level to ground

at the output, ensuring that the sync-tip voltage level is set to

approximately -300mV at the back-termination resistor of a

standard video load. The ISL59831 is capable of driving two

AC or DC coupled standard video loads. The device also

features a 4th order Butterworth reconstruction filter with

nominal -3dB frequency set to 9.1MHz, providing 44dB of

attenuation at 27MHz. When powered down, the device

draws 2µA supply current. Nominal operational current is

15mA. The ISL59831 is available in 12 Ld TDFN package

and operates from the -40°C to +85°C temperature range.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are 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.
