TW2964-LA2-CR128 - Renesas Electronics

Description: The TW2964 is a low power NTSC/PAL video decoder chip that is designed for video surveillance applications. It consumes very low power in a typical composite input application. The available power down mode further reduces the power consumption. It uses the 1. 0V for digital supply voltage and 3. 3V for I/O and analog power. A single 27MHz crystal is all that needed to decode all analog video standards. The video decoder decodes the base-band analog CVBS into digital 8-bit 4:2:2 YCbCr for output. It consist

TW2964-LA2-CR128 Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a dedicated ground plane and thermal vias is recommended for optimal thermal performance. Ensure that the thermal pad is connected to a solid ground plane to dissipate heat efficiently.
  • Implement proper EMI shielding, use differential signaling, and add capacitors for power supply decoupling. Also, consider using a common-mode choke to reduce electromagnetic interference.
  • Power up the device in the following sequence: VCC, AVCC, and then DVCC. Ensure that the power supplies are stable and within the recommended voltage range before applying the clock signal.
  • Check the ADC clock frequency, ensure proper analog input signal conditioning, and verify that the ADC is not saturated. Also, review the datasheet's ADC calibration procedure and consider using an external reference voltage.
  • Use a low-dropout regulator (LDO) with a high power supply rejection ratio (PSRR) to minimize noise and ripple. Ensure the power supply can handle the device's peak current requirements, and consider adding decoupling capacitors to reduce noise.
