Notes:
2.
The maximum bus frequency depends on the mode:
鈥?In 60x-compatible mode connected to another MSC8101 device, the frequency is determined by adding the input and output
longest timing values, which results in a frequency of 75 MHz for 30 pF output capacitance. In multi-master mode when
connected to another MSC8101 device, the frequency is determined by adding the input and output longest timing values,
which results in a frequency of 75 MHz for 30 pF output capacitance.
鈥?Certain bus modes, such as non-extra cycle (EXDD = 1), non-pipelined, and ECC/Parity modes, result in slower bus
frequencies.
鈥?In single-master mode, the frequency depends on the timing of the devices connected to the MSC8101.
Output specifications are measured from the 50% level of the rising edge of DLLIN to the 50% level of the signal. Timings are
measured at the pin.
