6.1.3.1.1 MCU_OSC0 (High Frequency) Clock (Internal Oscillator) or LVCMOS Digital Clock (External Oscillator)

MCU_OSC0 25MHz (mandatory) reference clock is required for the processor to operate. The clock is used internally to generate a number of clocks that are required for the processor to operate. The other clock inputs depends on specific end equipment or board functionality implemented. Clocking option supported includes external crystal + internal oscillator or external 1.8V LVCMOS square-wave digital clock source. Spread spectrum clocking (clock input) is not a supported clock option.

In case 25MHz external crystal connected to the internal high frequency oscillator (MCU_HFOSC0) is the clock source for the internal processor operation, the recommendation is to place the discrete load capacitors used to implement the oscillator circuit close to the MCU_OSC0_XI and MCU_OSC0_XO pins. When crystal based oscillator is implemented, the recommendation is to follow the MCU_OSC0 Crystal Circuit Requirements table of the processor-specific data sheet for choosing the load capacitors. The load capacitor capacitance value includes the PCB capacitance. The recommendation is to refer to Clock Routing Guidelines, Oscillator Routing section of the processor-specific data sheet for placement and routing of the crystal and load capacitors.

A 1.8V LVCMOS clock source can be used as processor clock source. When clock output from the external oscillator is connected to the XI input (through a series resistor), the recommendation is to ground XO as per the recommendations in the processor-specific data sheet. The inverter shown in the (figure 1.8V LVCMOS-Compatible Clock Input in the processor-specific data sheet) was meant to represent an LVCMOS output, where the LVCMOS output can be the oscillator output buffer, or the LVCMOS output from some clock distribution device. There is no requirement to invert the clock source.

For more information on LVCMOS clock source including specifications, see the following FAQ:

[FAQ] AM625 / AM623 / AM620-Q1 / AM625-Q1/ AM625SIP / AM62A7 / AM62A3 / AM62A1-Q1 / AM62D-Q1 / AM62P / AM62P-Q1 / AM62L Custom board hardware design – Queries regarding LVCMOS Digital Clock Source for, MCU_OSC0 (WKUP_OSC) or WKUP_LFOSC0 (LFOSC0)

Internal AC coupling capacitors have been implemented on both XI and XO signal paths that connect to an internal comparator that creates a square wave. A DC steady-state condition on the XI pin relative to the XO pin allows the comparator to generate glitches on the internal clock tree of the device and cause the clock circuit to do unpredictable operations. Connecting a DC input to XI is not recommended or allowed.

The FAQ is generic and can also be used for AM62P, AM62P-Q1 processor family.

Note:

25MHz is the only crystal frequency currently supported. See the processor-specific data sheet for information on the supported crystal frequency and recommended crystal parameters.

Refer MCU_OSC0 LVCMOS Digital Clock Source, MCU_OSC0 LVCMOS Digital Clock Source Requirements section of the processor-specific data sheet.

When an external clock (LVCMOS) oscillator is used as the clock source for the processor and the EPHY (EPHy, EPHYs), a single oscillator can be used or separate (individual) oscillators can be used. When a single oscillator is used, the clock output is recommended to be buffered before connecting to processor and EPHy.

Single output buffer (individual ICs) for processor and EPHy or dual or multiple output buffer (single IC) with a single input for processor and EPHy, can be used to connect the clock output from the oscillator to the processor and the EPHy.

For specific use case (requirement for some of the industrial applications using Time Sensitive Networking (TSN)), two or more output (based on number of EPHYs used) buffer with a single input is recommended for the processor and the EPHy.
