CDCLVD110AVFRG4

The CDCLVD110AVFRG4 is a high-speed clock buffer, driver, and multiplexer integrated circuit from Texas Instruments. It is a low voltage differential signal (LVDS) solution that integrates a 2:1 Mux with a PLL clock driver to reduce and condition clock trees. The device is based on the company\'s best-in-class dual-octal architecture and provides two high-speed clock buffers and one high-frequency clock driver. This device is ideal for applications where it is necessary to separate clock and data signals and reduce noise levels in the system. The CDCLVD110AVFRG4 is designed for use in portable, based multimedia, video streaming, and audio/video systems, as well as sensitive radio-frequency (RF) applications.

The CDCLVD110AVFRG4 works by taking a high-speed clock input (2 to 3.6 GHz with pre-emphasis) and buffering it with two low-skew outputs into two LVPECL or LVDS loads. The output of these buffers can be connected to multiplexer inputs. One input looks at the external high-speed clock signals and the other looks at the multiplexer output. When the multiplexer is enabled, the output of the PLL clock driver is fed back through the multiplexer input to reduce and stabilize the clock tree. This PLL clock driver utilizes 17 ps clock jitter and < 115fs RMS jitter to ensure both the stability and accuracy of the clock signal.

The CDCLVD110AVFRG4 provides significant performance advantages: designed for tight time budget conditions, the device has a propagation delay of 30 ps, typical clock-to-output skew of 38 ps, and typical output-to-output skew of 33 ps. The jitter performance is excellent, with an output jitter of 10 ps, and individual jitter of 14ps for a wide range of outputs. This device is a low-voltage (2.5V) low-power dissipating device that is optimized for very low power or high data rate applications. The 2.5V supply voltage is also well suited for many applications, including those utilizing multiple ASICs.

The CDCLVD110AVFRG4 is a highly versatile clock solution that can be used in a wide range of applications. In audio/video systems, it can be used to separate the clock and data signals to reduce noise levels in the system. In network systems, it can reduce total jitter across the system. It can also be used in communication links and distributed clock networks, providing superior jitter performance in high-speed systems. Additionally, for applications like video streaming, the device can be used to ensure that audio and video signals maintain the same phase and frequency.

In summary, the CDCLVD110AVFRG4 is an excellent low-voltage high-speed clock solution from Texas Instruments. It provides excellent performance in applications where clock and data must be separated, reducing noise level and increasing efficiency across the system. It is ideal for audio/video systems, network systems, communications links, distributed clock networks, and video streaming applications.
