CDCVF2505DR

The CDCVF2505DR from Texas Instruments is a high-performance, low-skew, low-jitter phase-lock loop (PLL) clock driver. It operates from a single 3.3V supply and is designed for synchronous DRAM and general-purpose applications. This device distributes one clock input to one bank of five outputs, including CLKOUT, which can be used to tune the input-output delay. The outputs are automatically three-stated when there is no input clock.

Key electrical specifications include an operating frequency range of 24 MHz to 200 MHz, with low cycle-to-cycle jitter of less than 150 ps over the 66 MHz to 200 MHz range. It offers 4 LVCMOS outputs and supports a core supply voltage of 3.3V. The device also features integrated 25-ohm on-chip series damping resistors, making it suitable for driving point-to-point loads.

The CDCVF2505DR is available in an 8-pin SOIC package and operates within a temperature range of -40°C to 85°C. It includes an internal feedback loop to synchronize outputs to the input clock and an integrated RC PLL loop filter, eliminating the need for external components. The device automatically enters a power-down mode when no input signal is applied, consuming less than 100 mA typical in this state.
