  • Description

    The CDCV857DGGR is a high-performance, low-skew, low-jitter phase-locked loop (PLL) clock driver designed for use with DDR (Double Data Rate) synchronous DRAMs. It is specifically designed to support a wide operation range of 60 MHz to 200 MHz.

    Specifications and features

    - Distributes one differential clock input pair to ten differential clock output pairs.

    - Supports spread spectrum clock requirements meeting the PC100 SDRAM registered DIMM specification.

    - External feedback pins (FBIN, FBIN) are used to synchronize the outputs to the clock input.

    - Supports 2.5V analog supply voltage (AVCC) and 2.5V VDDQ.

    - No external RC network required.

    - Sleep mode detection.

    - 48-pin TSSOP (Thin Shrink Small Outline Package).

    Application Scenarios

    The CDCV857DGGR is commonly used in clock generator applications, frequency synthesizers, and PLL circuits. It can be integrated into various electronic devices that require precise and synchronized clock signals, such as computer systems, networking equipment, and communication devices.

    Comparison

    The CDCV857DGGR offers several advantages:

    - High performance with low skew and low jitter.

    - Wide operation range of 60 MHz to 200 MHz.

    - Support for spread spectrum clock requirements.

    - Easy synchronization of outputs to the clock input using external feedback pins.

    - Integration of sleep mode detection for power-saving purposes.

    - Compact 48-pin TSSOP package for space-saving designs.

    However, it also has some limitations:

    - Limited to support 2.5V analog supply voltage (AVCC) and 2.5V VDDQ.

    - External RC network is not required, but it may be necessary for specific applications.
