Hello, I was wondering, what is the maximum sampling rate/frequency that can be achieved using the eQEP modules?

Alejandro,

Please see Section 5.9.4.2.5 Enhanced Quadrature Encoder Pulse (eQEP) Timing in SPRS439: www.ti.com/.../specifications

The QEP can operate at the maximum of 2[1tc(SCO) + tw(IQSW)] where tw(IQSW) is the GPIO input qualification period and tc(SCO) is the SYSCLK cycle time.

Thanks,
Mark
