Description
The MC44C402AC is a CMOS family of RF modulators, which is an upgrade version of the MC44BS373/4 devices. It is designed for use in VCRs, set-top boxes, and similar devices. The modulator supports multiple standards, including NTSC, PAL, SECAM (B/G, I, D/K, L, M/N). It also operates in the UHF frequency range of 460 MHz to 880 MHz.
Specifications and features
- Multi-TV standard support: NTSC, PAL, SECAM (B/G, I, D/K, L, M/N).
- Programmable UHF oscillator and sound subcarrier oscillator.
- On-chip tank circuits, no external varicaps inductors or tuned components required.
- Program control via 800 kHz high-speed I2C-bus.
- Programmable sound reference frequency of 31.25 kHz or 62.5 kHz.
- Direct sound modulator input (FM and AM).
- Auxiliary input bypasses AM/FM modulators for NICAM or BTSC applications.
- Video modulation depth of 96% typ. in system L and 85% typ. in other standards.
- Programmable peak white clip levels.
- On-chip video test pattern generator with sound test signal (1 kHz).
- Low-power standby mode.
- Output inhibit during PLL Lock-up at power-ON.
- Logical output port controlled by I2C-bus.
Application Scenarios
The MC44C402AC is widely used in VCRs, set-top boxes, and similar devices that require RF modulation. It is especially useful for devices that support multiple TV standards such as NTSC, PAL, and SECAM.
