Overview
The CDCVF2505DRG4 is a high-performance, low-skew, low-jitter phase-lock loop (PLL) clock driver produced by Texas Instruments. This device is designed to precisely align the output clocks to the input clock signal in both frequency and phase, making it ideal for synchronous DRAM and general-purpose applications. It operates on a single 3.3-V supply and is characterized for operation from –40°C to 85°C.

Key Features
- High-performance, low-skew, low-jitter phase-lock loop (PLL) clock driver
- Operates from a single 3.3-V supply
- Operating frequency range: 24 MHz to 200 MHz
- Low jitter (cycle-to-cycle): < 150 ps over 66 MHz to 200 MHz range
- Distributes one clock input to one bank of five outputs (CLKOUT used to tune the input-output delay)
- Three-state outputs when there is no input clock
- Integrated RC PLL loop filter eliminates the need for external components
- Internal feedback loop synchronizes the outputs to the input clock
- 25-Ω on-chip series damping resistors
- Consumes less than 100 mA (typical) in power-down mode
Applications
The CDCVF2505DRG4 is suitable for various applications, including synchronous DRAM and general-purpose clock distribution. It is particularly useful in systems requiring low-skew, low-jitter clock signals, such as in telecommunications, data storage, and high-speed computing systems.
