DescriptionQUAD PLL FIELD PROGRAMMAB
The 348RP is a field programmable clock synthesizer that generates up to nine high-quality, high-frequency clock outputs including multiple reference clocks from a low-frequency crystal or clock input. The 348RP has four independent on-chip PLLs and is designed to replace crystals and crystal oscillators in most electronic systems.
Using IDT VersaClock software to configure PLLs and outputs, the 348RP contains a One-Time Programmable (OTP) ROM to allow field programmability. Programming features include eight selectable configuration registers and up to two sets of four low-skew outputs.
Using Phase-Locked Loop (PLL) techniques, the device runs from a standard fundamental mode, inexpensive crystal, or clock. It can replace multiple crystals and oscillators, saving board space and cost.
The 348RP is also available in factory programmed custom versions for high-volume applications.
