Renesas Electronics Corporation Clock Generators, PLLs, Frequency Synthesizers IDT2308-4DCI

The IDT2308-4DCI is a high-speed phase-lock loop (PLL) clock multiplier designed for clock distribution applications with operating frequencies ranging from 10MHz to 133MHz. It features zero delay by aligning the phase of the incoming clock with the output clock, ensuring minimal output skew of less than 200 ps and low jitter of less than 200 ps cycle-to-cycle. The device distributes one clock input to two banks of four outputs, each with separate output enable controls, and can be configured for 2x output multiplication. This clock multiplier operates at a supply voltage of 3.3V and does not require an external RC network. It is available in both SOIC and TSSOP packages and is characterized for both commercial (0 to +70°C) and industrial (-40 to +85°C) temperature ranges. The IDT2308-4DCI also includes a power-down mode that reduces current consumption to less than 25µA when no input clock is present. This product is suitable for applications in SDRAM, telecom, datacom, and PC motherboards/workstations.
