RENESAS 307GI-03LFT

An advanced PLL coupled to an array of configurable output dividers and three outputs allows low-jitter generation of frequencies from 200 Hz to 270 MHz. The device can be reprogrammed during operation, making it ideal for applications where many different frequencies are required, or where the output frequency must be determined at run time. Glitch-free frequency transitions, where the clock period changes slightly over many cycles, are possible.

• Crystal or clock reference input
• 3.3 V CMOS outputs
• Three outputs can be individually configured or shut off
• Small 16-pin TSSOP package – Pb-free, RoHS compliant
• Reprogrammable during operation
