Synchronization The LT1249 can be externally synchronized in afrequency range of 127kHz t0 160kHz. Figure 2 shows the synchro- nizing circuit. Synchronizing occurs when CAOUT pin is pulled below 0.5Vwith an externaltransistorand a Schottky diode. The Schottky diode and the 10k pull-up resistor are necessary for the required fast slewing back up to the normal operating voltage on CAOUT after the transistor is turned off. Positive slewing on CAOUT should be faster than the oscillator ramp rate of 0.5V/~.
