ICS9179BF-03T is a clock buffer and driver device designed to fan-out clock signals efficiently. This device is a high performance clock driver and buffer with the capability to drive nine copies of the same clock signal with low skew and jitter characteristics. It offers two power saving modes, dynamic and standby, and an integrated ESD protection. It can be used for single-ended, dual-ended and spread spectrum clock applications.

The ICS9179BF-03T can be used in a variety of application fields, such as embedded and consumer systems, mobile and wired networks, base stations, radar systems and audio systems. It can be used in high speed communications such as SerDes, Ethernet, and USB links, as well as in low speed bus applications such as I2C and SPI links. It is also applicable in storage and gaming systems, clocks for DDR and GDDR, and high speed copies of the same clock signal.

The ICS9179BF-03T consists of an integrated and programmable clock buffer, a low impedance differential driver, and an output multiplexer. The buffer is controlled by an integrated clock multiplier and a duty cycle adjuster. The clock multiplier multiplies the frequency of the clock signal by three to four times, and the duty cycle adjuster adjusts the duty cycle of the output clock signal within a range of 50-100 percent.

The ICS9179BF-03T utilizes a single, low power, differential clock to fan-out up to nine independent, low skew and jitter copies of the clock signal. The device provides two power saving modes, dynamic, where the clock is turned on or off based on the user input, and standby, where the device remains active but all clock output drivers are disabled. The device also incorporates an integrated ESD protection circuit to protect all the outputs.

The ICS9179BF-03T utilizes a unique clock driver architecture that provides the lowest propagation delay out of any clock driver device in the industry. This architecture relies on the trimming of the operating voltage of the output flip-flop by a few millivolts to achieve low jitter and low skew performance. The clock driver provides up to 2.5pF of load capacitance, allowing it to drive up to nine loads on each output with extremely low precharge times.

Furthermore, the ICS9179BF-03T provides programmable overvoltage and undervoltage protection circuitry to prevent output voltage leakage and false triggering due to ESD events. This makes it ideal for industrial and automotive applications.
