4. This specification applies only to the case where the HSP48908 is being written to during an active convolution cycle. It must be met in order to
5. While FRAME is an asynchronous signal, it must be deasserted a minimum of T
6. Transition is measured at 200mV from steady state voltage with loading as specified in test load circuit with C
7. AC Testing is performed as follows: Input levels (CLK Input) 4.0 and 0V, Input levels (all other Inputs) 0V and 3.0V, Timing reference levels (CLK)
8. Controlled via design or process parameters and not directly tested. Characterized upon initial design and after major process and/or design
achieve predictable results at the next rising clock edge. In most applications, the configuration data and coefficients are loaded asynchronously
