描述

The 276 field programmable VCXO clock synthesizer generates up to three high-quality, high-frequency clock outputs including multiple reference clocks from a low-frequency crystal input. It is designed to replace crystals and crystal oscillators in most electronic systems. Using IDT's VersaClockTM software to configure PLLs and outputs, the 276 contains a One-Time Programmable (OTP) ROM for field programmability. Programming features include VCXO and eight selectable configuration registers. Each of the outputs are powered by a single VDDO voltage. VDDO may vary from 1.8 V to VDD. Using Phase-Locked Loop (PLL) techniques, the device runs from a standard fundamental mode, inexpensive crystal, or clock. It can replace VCXOs, multiple crystals and oscillators, saving board space and cost. The 276 is also available in factory programmed custom versions for high-volume applications.
