TPD7201F Datasheet counts off 128 DIV_CLK before setting REF_REQ. REF_REQ is held active until MSTR_CON acknowl- edges this request by issuing a REF_ACCESS. This then resets the REF_REQ bit. The count of 256 33-ns cycles gives a refresh of 8.45 vs, which is an over re- fresh butaccounts forthe possibility ofan Am29030 pro- cessor burstlosing awhole cycle countin the REFRESH PAL device.

TPD7201F on stock The Error Signal, after limited and filtered, is sent to Digitally Controlled Oscillator. Based on the processed error value, the DCO will generate the corresponding digital output signals for the Tapped Delay Line in the Output Interface Circuit to produce 12.352MHz, 12.624MHz, 19.44MHz and 16.3 84MHz signals. The DCO synchronization method depends upon the PT7A4408/4408L operating state, as follows:
