ClockBuilder Pro Field Programmer

When used with ClockBuilder Pro software, the ClockBuilder Pro Field Programmer makes it simple for systems designers to develop, program, and debug any Si5332/8, Si5350/1/6/7, Si534x/6x/8x/9x, Si540x, and Si55xx part families clock device “in-system,” or in one of the convenient QFN sockets. The field programmer supports I2C or SPI interfaces to the host system, and SPI to the field programmer's QFN socket boards.
