309RILFT - Renesas Electronics

Description: The 309 is a versatile serially-programmable, triple PLL with spread spectrum clock source. The 309 can generate any frequency from 250kHz to 200 MHz, and up to 6 different output frequencies simultaneously. The outputs can be reprogrammed on-the-fly, and will lock to a new frequency in 10 ms or less. To reduce system EMI emissions, spread spectrum is available that supports modulation frequencies of 31 kHz and 120 kHz, as well as modulation amplitudes of +/-0.25% to +/-2.0%. Both center and down-spread opt
