A good PCB layout for the TS952IDT involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the power supply. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
The TS952IDT requires a single 3.3V power supply. It's recommended to use a low-dropout linear regulator (LDO) to power the device. The power sequencing requirement is to power up the device after the power supply has stabilized, and to ensure that the power supply is stable before enabling the device.
The recommended clock frequency for the TS952IDT is 25 MHz, but it can operate up to 50 MHz. The clock signal quality should be as clean as possible, with minimal jitter and noise. A clock signal with a duty cycle of 50% and a rise/fall time of less than 5 ns is recommended.
The TS952IDT can be configured for different video formats and resolutions using the device's registers. The device supports various video formats, including NTSC, PAL, and SECAM, and resolutions up to 1080p. The configuration is done through the I2C interface, and the specific register settings depend on the desired video format and resolution.
The TS952IDT has a maximum junction temperature of 150°C. To ensure reliable operation, the device should be operated at a temperature below 85°C. Thermal management considerations include using a heat sink, ensuring good airflow, and avoiding thermal hotspots on the PCB.
