The 548-05 is a low-cost, low-jitter, high-performance clock synthesizer designed to produce x16 and x24 clocks from T1 and E1 frequencies. Using Renesas’ patented analog/digital Phase-Locked Loop (PLL) techniques, the device uses a crystal or clock input to synthesize popular communications frequencies. Power down modes allow the chip to turn off completely, or the PLL and clock output to be turned off separately.
