4 / 10 page SM1124 Series NIPPON PRECISION CIRCUITS—4 CLK input clock SC input clock Serial input FUNCTIONAL DESCRIPTION Control Functions External reference clock The SM1124 can operate at 12 selectable external reference clock frequencies. Of these, 8 are selectable for each tune. When multiple external clock frequencies are input to a single IC, the clock must be switched during playback mode. Note that when the frequency in parentheses is selected, all tunes can only be played using that single fixed frequency. • 32.768 kHz system: 32.768 kHz, 65.536 kHz, (131.072 kHz) • 37.5 kHz system: 37.5 kHz, 75.0 kHz, (150.0 kHz) • 38.4 kHz system: 38.4 kHz, 76.8 kHz, (153.6 kHz) • 48.0 kHz system: 48.0 kHz, 96.0 kHz, (192.0 kHz) VIH VIL CWH t CWL t CLK t 0.5VDD CLK VIH VIL SWH t SWL t SC t 0.5VDD SC VIH VIL 0.5VDD SC VIH VIL 0.5VDD SI DS t DH t The external reference clock input is used at any time as well as during playback mode. If a clock signal is input when not in playback mode (when ST is LOW), the gate circuit switches to cutoff the external reference clock signal from entering the device, preventing unwanted current flow. |
