High-performance Video Driver Series
Y/C MIX Circuit built-in Video Driver
BA7664AFV
No.09065EAT02
Description BA7664AFV is a 75 video driver, packaged in SSOP-B8, incorporating a 6dB amplifier, Y/C MIX circuit, sag compensation, and Mute function. This driver can drive two 75 loads. While the composite Y signal input is sync-tip-clamp, the chroma input has an internal termination at 20k. The device also incorporates a power save circuit by activated when the output is under 0.2V.
Features 1) A low consumption electric power movement 2) Built-in output mute circuit 3) Built-in power save circuit 4) Built-in output protection circuit 5) Low output coupling capacitor value can be used due to a built-in sag compensation circuit 6) The driver can have two loads (each channel) 7) Built-in Y/C MIX circuit
Applications DVD, DVC, DSC, STB, and visual instruments.

Cautions on use 1. 2. Numbers and data in entries are representative design values and are not guaranteed values of the items. Although ROHM is confident that the example application circuit reflects the best possible recommendations, be sure to verify circuit characteristics for your particular application. Modification of constants for other externally connected circuits may cause variations in both static and transient characteristics for external components as well as this ROHM IC. Allow for sufficient margins when determining circuit constants. Absolute maximum ratings Use of the IC in excess of absolute maximum ratings, such as the applied voltage or operating temperature range (Topr), may result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or open mode) when such damage is suffered. A physical safety measure, such as a fuse, should be implemented when using the IC at times where the absolute maximum ratings may be exceeded. GND potential Ensure a minimum GND pin potential in all operating conditions. Make sure that no pins are at a voltage below the GND at any time, regardless of whether it is a transient signal or not. Thermal design Perform thermal design, in which there are adequate margins, by taking into account the permissible dissipation (Pd) in actual states of use. Short circuit between terminals and erroneous mounting Pay attention to the assembly direction of the ICs. Wrong mounting direction or shorts between terminals, GND, or other components on the circuits, can damage the IC. Operation in strong electromagnetic field Using the ICs in a strong electromagnetic field can cause operation malfunction.
