BIT1628A

The BITEK BIT1628A is a versatile 10-bit digital video decoder designed for image processing applications. It integrates one 10-bit video CMOS Analog-to-Digital Converter (ADC) for optimal signal-to-noise performance. The device offers fully programmable static or automatic gain control (AGC) with ranges up to 12 dB for analog and 18 dB for digital signals.

Key features include an on-chip clock generator with a digital PLL for synchronization across various video standards, including NTSC, PAL, and SECAM. It accepts a single crystal for all standards and automatically detects 50/60 Hz field frequencies. The BIT1628A supports user-programmable luminance peaking, adaptive comb filters, and PAL delay lines for accurate color and luminance separation.

This decoder includes embedded features such as brightness, contrast, sharpness, and gamma correction, along with Skin-Tone and CTI enhancement. An integrated OSD generator with ROM fonts and overlay capabilities is also present. The output consists of 3x8 bits digital RGB ports, supporting a maximum pixel frequency of 85MHz. The device operates with a 1.8V core power supply and a 3.3V supply for output pads, consuming less than 300 mW.

The BIT1628A is available in a 64-pin LQFP package. Its interface supports the Two-Wire Serial Interface (TWSI) bus and 24Cxx serial EEPROM boot. This component is suitable for applications requiring robust video decoding and display processing capabilities.
