ISL59834 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 4th order Butterworth reconstruction filter that provides 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.
