LA7685J

The LA7685J is a single-chip IC (with VIF, SIF, video,chroma, and deflection circuits built in) for use in PAL or NTSC television sets.Because the PLL+ splitting method is used in the VIF circuit,the LA7685J is suited for use in top-of-the-line small and mid-size television sets. In addition, when used in combination with the LA7640N SECAM chroma IC, the LA7685J can be used in a PAL/NTSC/SECAM multisystem set.

The LA7685J has the following features including:(1)adjustment-free horizontal and vertical sync; (2)excellent anti-noise characteristics due to adoption of duplex AFC; (3)vertical sync sensitivity can be adjusted externally; (4)constant vertical size with no signal (constant for 60/50 Hz); (5)highly stable image during copy guard tape playback(macrovision tapes, etc.); (6)excellent stability against VCR skew distortion.

The absolute maximum ratings of the LA7685J are:(1)operating temperature:-10 to 65; (2)storage temperature range:-55 to 150; (3)maximum supply voltages:11V; (4)maximum supply current:16mA;(5)allowable power dissipation:1.53W.The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics.
