RTC clock synchronization buffer driver delay chip

Windowed Watchdog Timer with Programmable Reset Delay 10-VSON -40 to 125

The NB7V32M is a differential divide-by-2 clock divider with asynchronous reset. The differential clock inputs include internal 50 Ω termination resistors and accept LVPECL, CML, and LVDS logic levels. The NB7V32M generates a divide-by-2 output copy of the input clock, operating at frequencies up to 10GHz with minimal jitter. The reset pin is active on a rising edge. On power-up, an internal flip-flop will go into a random state; resetting allows multiple NB7V32Ms in the system to synchronize. The 16mA differential CML output provides a matched internal 50Ω termination that provides an output swing of 400mV when the external receiver is terminated into 50Ω to VCC. The NB7V32M is a 1.8V/2.5V version of the NB7L32M 2.5V/3.3V, packaged in a tiny 3mm x 3mm 16-pin QFN package.

The NB7VQ572M is a high performance differential 4:1 clock/data input multiplexer and 1:2 CML clock/data fanout buffer operating up to 7 GHz / 10 Gbps. Each INx / INx input pair contains a fixed equalizer receiver that, when placed in series in the data path, will boost degraded signals traveling through FR4 backplane or cable interconnects. For applications that do not require equalization, consider using the NB7V572M, which is pin-to-pin compatible with the NB7VQ572M. The differential clock/data inputs have internal 50 Ω termination resistors and accept differential LVPECL, CML, or LVDS logic levels. The NB7VQ572M includes a pair of select pins that will select one of four differential inputs and will produce two identical copies of the clock or data CML output. Therefore, the NB7VQ572M is suitable for SONET, GigE, Fiber Channel, backplane and other clock/data distribution applications. When externally loaded and terminated with a 50 Ω resistor to VCC, the two differential CML outputs swing 400mV and are optimized for low skew and minimal jitter. The NB7VQ572M belongs to the GigaComm family of high-performance clock products.
