For the components in the sequential circuit shown below, ${\mathit{t}}_{\mathrm{pd}}$ is the propagation delay, ${\mathit{t}}_{\mathrm{setup}}$ is the setup time, and ${\mathit{t}}_{\mathrm{hold}}$ is the hold time. The maximum clock frequency (rounded off to the nearest integer), at which the given circuit can operate reliably, is .... MHz.
