Programmable clock generator spi.

I revised january 23 2009 features integrated phase locked loop pll commercial and industrial operation flash programmable field programmable. The sit9105 is the industry s first 3 pll programmable clock generator with an embedded mems resonator that combines one differential and two single ended outputs. An industry standard i2c serial programming interface spi is used to program the scratchpad and clock core. For simplified evaluation of the si5330 34 35 38 any frequency any output quad clock generators and buffers development kits are available.

16 kbit eeprom the 16 kbit eeprom scratchpad is organized in eight blocks x 256 words x 8 bits. 1 to 340 mhz i2c spi programmable oscillator. 1 to 60 mhz stratum 3e ocxo. It offers a factory programmable pll output that can be set to almost any frequency ranging from 4mhz to 200mhz.

340 to 725 mhz i2c spi programmable oscillator. This makes them well suited for consumer data communications telecommunications and computing applications. About clock generators and frequency synthesizers clock synthesizers a clock signal generator is a circuit that produces a timing signal for use in synchronizing a system s operation. At its most basic level a clock generator consists of a resonant circuit and an amplifier.
