The Renesas Electronics Versa clock low power PLL is a programmable clock generator intended for low power, battery operated consumer applications. There are four internal PLLs, each individually programmable, allowing for up to five different output frequencies. The frequencies are generated from a single reference clock. The reference clock can come from either a TCXO or fundamental mode crystal. The versa clock low power PLL can be programmed through the use of the I2C interfaces. The programming interface enables the device to be programmed when it is in normal operation or what is commonly known as in system programmable. An internal EEPROM allows the user to save and restore the configuration of the device without having to reprogram it on power-up.
