LA73074CL
Overview
Monolithic Linear IC
Video Driver for DSC/Cell Phone
The LA73074CL is a low voltage drive (2.7V to 3.6V) video driver developed for portable appliances including digital still cameras and cell phones. It incorporates a minus-voltage generator that allows the LA73074CL to generate its output with the pedestal voltage set to 0V, so that no output coupling capacitor is required. This enables substantial reduction in mounting space without concerned about V-sag.
Features
* Output coupling capacity not required * Low-voltage drive (VCC = 2.7V to 3.6V) * V-sag * Sextic LPF incorporated (fc = 7.5MHz) * Current drain of 0A in the standby mode * Amplifier gain selectable from three options (6, 12, and 9dB) (Pin control (GND/Open/VCC)) * Output drive capable of covering maximum 75 output, one channel

(Note 2) Use the input capacity value within a range of 0.1 F to 1F while checking the sag condition of the output waveform.
(Note 3) For these two capacities; Temperature characteristic B rank ( 10%) Electrostatic tolerance K rank(10%) and Withstand voltage of 6.3V or more are recommended.
(Note 4) Wiring from V OUT (pin 9) to 75 must be as short as possible.
(Note 5) As the minus power supply in this IC generates the clock for charge pump power supply by extracting the sink component of the input Video signal (synchronous isolation) and by detecting its fall, the portion around the V-syncrhonization of this IC output may be reduced when the pseudo V signal without cut-in pulse is inserted as in the case of certain analog VCR special play (search). On the contrary, there is no problem when the pseudo V signal has the cut-in pulse. Pay due attention on this fact duri ng use.
