The LMK01010ISQE/NOPB is a low jitter clock buffer driver designed to redistribute, fanout and synthesize high-performance clocks. It is widely used in consumer and industrial electronics applications such as cellular base stations, digital set-top boxes, dvr\'s and media centers. The LMK01010ISQE/NOPB clock buffer driver is specifically designed to reduce the timing jitter, improve clock signal integrity and simplify system design by eliminating the need for multiple oscillators and discrete devices.

The LMK01010ISQE/NOPB is a variable frequency clock driver and synthesizer that can generate a wide range of frequencies (100 kHz to 200 MHz) and different clock waveforms, such as differential square wave, sine wave, pulse wave, and so on. The clock buffer driver is composed of a 4-stage pipeline where each stage consist of a fractional-N divider, a pre-scalar and a programmable output buffer. The programmable output buffer supports both LVPECL and LVDS output levels. The pre-scalar can reduce the frequency by a factor of 2, 4, 8, 16 or 32 and the dividers can divide the output frequency by an integer from 1 to 4096.

The LMK01010ISQE/NOPB clock buffer driver is a highly integrated system that simplifies the design by combining an oscillator, multiple dividers, buffers, and programming logic in a single package. The onboard clock synthesizer can generate any frequency from 100 kHz to 200 MHz and provides low jitter digital outputs (200ps or less). The chip supports selection of three different voltage levels for the output clock; 2.5V, LVDS (1.8V) and LVPECL (3.3V). The chip also supports spread spectrum reduction function and programmable skew between outputs.

The LMK01010ISQE/NOPB is also equipped with advanced power management features such as a programmable soft-start and output disable feature that reduce the startup power required by the application. The device supports both an I2C serial bus interface and a standard parallel bus interface to configure the clock output frequency and other related settings.

The LMK01010ISQE/NOPB is a flexible clock buffer driver and synthesizer that can be used for a variety of applications including clock tree synthesis, clock skew reduction and jitter attenuation. It is ideal for mobile and digital consumer applications that require multiple clocks and need to minimize system cost and complexity.
