DESCRIPTION
The PL613-21 is an advanced three PLL design based on PicoPLL, the world’s smallest programmable clock
technology. This advanced technology allows the PL613 -21 to fit in to a small 3x3mm QFN package for high
performance, low-power, small form-factor applications. By using the individual output buffer VDD pins, the
PL613-21 can support multiple output voltage requirements. In addition, CLK1 has the ability to generate kHz
outputs and is ideal for generating 32.768kHz outputs.
The unique power down features of the PL613-21 allows the user to shut down individual PLLs when the corresponding
clock output is disabled using the PDB pins. The output drive strength can be individually programmed on each output to
Low (4mA), Standard (8mA) or High (16mA) drive. In addition, the disabled state of the clock outputs can be
programmed as Hi-Z or Active Low.
Besides its small form factor and multiple outputs that can reduce overall system costs, the PL613 -21 offers superior
phase noise, jitter and power consumption performance.
