MM1757DH

MITSUMI HD-Compatible Video Driver IC MM1757 Series HD-Compatible Video Driver IC Monolithic IC MM1757 Series April 28, 2009 Outline This IC is a two-channel 75Ω video driver IC supporting HD (720p/D4, 1080i/D3). It provides the input and output for composite video (V), S-Video (Y, C), and Y color difference (CY, Cb, Cr) (only Y color difference input/output is HD-compatible). It supports both single and dual power supplies. If a single power supply is used, a sag correction circuit can reduce output capacitance, while no output capacitance is required if a dual power supply is used. It also includes an LPF (VCVS Butterworth) required after D/A conversion, D-terminal identification signal (line 1 - line 3) and S-terminal identification signal (S1, S2) output functions, which is ideal as an output driver for Hi-Vision (HD) signal output equipment such as set-top boxes (STBs) and DVD, Blu-ray recorders. Phased Out Products Features 1. Supports the Hi-Vision signal 2. Supports single power supplies and dual power supplies 3. Includes a VCVS Butterworth LPF 4. Includes D-terminal identification signal (line 1 - line 3) and S-terminal identification signal (S1, S2) output functions (F rank) 5. Two types of IC control methods are available; I2C bus control and DC control with a control pin (F rank) Item Model Input/Output terminal Power supply Output coupling capacitor D Terminal HD/SD switch I2C Bus control Clamp/Bias switch CVBS/Y/C (Bus bandwidth/Stop Bus bandwidth) ...
