Description:The 8302 is a low skew, 1-to-2 LVCMOS/LVTTL Fanout Buffer. The 8302 has a single-ended clock input. The single-ended clock input accepts LVCMOS or LVTTL input levels. The 8302 features a pair of LVCMOS/LVTTL outputs. The 8302 is characterized at full 3.3V for input VDD, and mixed 3.3V and 2.5V for output operating supply modes (VDDO). Guaranteed output and part-to-part skew characteristics make the 8302 ideal for clock distribution applications demanding well-defined performance and repeatability.
The recommended operating temperature range for the 8302AMLF is -40°C to 125°C, although it can tolerate storage temperatures from -55°C to 150°C.
The 8302AMLF has an internal POR and BOD circuitry. To handle POR, ensure a stable power supply and add an external capacitor to the VCC pin. For BOD, set the BOD threshold voltage and hysteresis using the BODV and BODH bits in the Power Management Control Register (PMC).
The 8302AMLF can operate at a maximum clock frequency of 32 MHz, although it can be overclocked to 40 MHz with reduced voltage and temperature ranges.
To configure the UART, set the baud rate using the UART Baud Rate Register (UBRR), enable the transmitter and receiver using the UART Control Register (UCSR), and configure the data bits, parity, and stop bits using the UART Frame Format Register (UCF).
The ADC converts analog input signals to digital values. To use the ADC, select the analog input channel using the ADC Channel Select Register (ADCSR), set the ADC clock using the ADC Clock Register (ADCC), and read the converted digital value from the ADC Data Register (ADCD).
