SYNC This connected either external clock directly SYNC another FC250x module. external clock signal applied SYNC pin, signal must (±50 kHz) square wave with Vp-p amplitude. Operation outside this frequency band will detrimentally affect performance module must avoided. SYNC connected SYNC another module, connection should direct possible, VI(-) pins modules must shorted together. Unused SYNC pins should tied VI(-). SYNC unused, module will operate from internal clock.
