NB7L1008MMNR4G

NB7L1008MMNR4G is a clock buffer, driver and distributor designed to distribute high-speed clock data signals with low skew, low jitter and excellent noise immunity. The NB7L1008MMNR4G from ON Semiconductor provides latch-up protection, output enable control, and a low active power output. This device is perfect for low-to-moderate-speed clock distribution applications in which high data rate, jitter, and low cross-talk noise are key requirements.

The NB7L1008MMNR4G is an 8-bit differential data/clock driver, each with two differential inputs and two differential outputs. The differential inputs can accept clock rates from DC to 250MHz; the differential outputs have a maximum clock rate of 800MHz. The inputs are designed to reduce noise by allowing input signals to be pre-emphasized and post-emphasized. The output stages are designed to buffer the incoming signals, providing a high level of fidelity and low distortion. The outputs provide active low output-enable logic, and the VDDIO pin controls the output enable/disable logic.

Once enabled, the NB7L1008MMNR4G outputs are designed to provide an output with zero total harmonic distortion and jitter less than 1ps (or 0.5 UI). Output skew is less than 500ps, and power consumption is a low 3.6mW. The NB7L1008MMNR4G operates from a single 2.5V supply, and provides both Schmitt-trigger inputs and variable-slew outputs.

The NB7L1008MMNR4G is also a latch-output chip, meaning that data from the inputs can be "latched" and maintained at the outputs, even when the differential inputs are not connected. This ensures stability in the clock signals, and prevents glitches or voltage oscillations when the outputs are re-enabled following a low-power or stand-by mode operation. Thanks to its latch circuitry, the NB7L1008MMNR4G can also be used in fail-safe and fail-silent applications, enabling systems with built-in redundancy.The NB7L1008MMNR4G is capable of operating in four different modes, depending on the application: standby, low-power, high-power, and maximum-speed. In the standard standby mode, the outputs are disabled and the chip consumes a very low 0.2mW of power, making it nearly undetectable. In low-power and high-power modes, the chip\'s outputs become enabled, but with varying power consumption. Finally, in the maximum-speed mode, the outputs are enabled and the chip consumes 3.6mW of power, allowing it to achieve its maximum data rate and clock frequency.

The NB7L1008MMNR4G is ideal for clock and data distribution applications in which signal integrity, low-power consumption, and low-jitter are critical criteria. It is particularly well-suited for mobile and wireless applications, where extreme signal integrity and low power consumption are paramount. Additionally, its latch output feature makes it an excellent choice for systems requiring fail-safing and/or auto-redundancy for improved robustness.
