5V PHASE LOCKED LOOP CLOCK DRIVER IDTCSPT855 • PLL clock driver for DDR (Double Data Rate) synchronous DRAM applications • Spread spectrum clock compatible • Operating frequency: 60MHz to 180MHz • Low jitter (cycle-to-cycle): ±50ps • Distributes one differential clock input to four differential clock outputs • Enters low power mode and 3-state outputs when input CLK signal is less than 20MHz or PWRDWN is low • Operates from dual 2.
5V supplies • Consumes 200µA quiescent current • External feedback pins (FBIN, FBIN) are used to synchronize outputs to input clocks • Available in TSSOP packa...
