Quad Channel, Single Supply, Video

Reconstruction Filter with On-Board

Charge Pump

The ISL59834 is a quad channel, single supply, video

reconstruction filter with integrated charge pump. It is

designed to operate on a single supply (3.0V to 3.6V) and

generate its own negative supply (-1.5V) using a regulated

charge pump. Input signals to the ISL59834 can be AC- or

DC-coupled. When AC-coupled, the backporch clamp sets

the blank level to ground at the output. Channels 1 and 3

have a sync detector whose output is available at

SYNC_OUTA and SYNC_OUTB, respectively. SYNC_INA

and SYNC_INB are inputs that provide timing for Channel 2

and Channel 4, respectively. Channel 2 and Channel 4 have

keyed clamps, which set the outputs to ground when

SYNC_INA or SYNC_INB are driven to the logic high state.

Each of the four outputs are capable of driving two DC or

AC-coupled standard video loads. The ISL59834 features a

9MHz nominal -3dB frequency and 40dB of attenuation at

27MHz. Nominal operational current is 63mA. When

powered down, the device draws 5µA maximum supply

current. The ISL59834 is available in a 44 Ld 7x7 QFN

package.

Ordering Information

NOTE: 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.
