A good PCB layout for CDCS503PWR involves keeping the input and output traces short and symmetrical, using a solid ground plane, and placing decoupling capacitors close to the device. TI provides a recommended layout in the datasheet and application notes.
Ensure a stable power supply, use a low-ESR capacitor (e.g., 10uF) close to the device, and add a 1uF capacitor between VCC and GND. Also, use a 0.1uF capacitor between VCC and AVCC for analog power supply decoupling.
The CDCS503PWR supports clock frequencies up to 100 MHz, but the actual frequency limit depends on the specific application, PCB layout, and signal integrity.
The CDCS503PWR can be configured for differential or single-ended input modes by setting the appropriate pins (e.g., DIFF/SE, INMODE) and using the correct input termination resistors. Refer to the datasheet and application notes for specific configuration details.
The typical power consumption of CDCS503PWR is around 150mW at 3.3V supply voltage, but this can vary depending on the specific application, clock frequency, and output loading.
