The TFF11101HN/N1,118 is specialized clock from Texas Instruments that is designed for use in clock applications that often don’t require higher levels of robustness.

The device is capable of driving buffer outputs for optimal flexibility, and it features a low-voltage differential signaling (LVDS) interface for easy data transfers. It’s also easy to configure via SPI, I2C, or UART, making the TFF11101HN/N1,118 suitable for a wide range of specific clock applications.

The TFF11101HN/N1,118 is structured around a single-pole multi-throw (SPMT) output buffer, with a user configurable pull-up or pull-down resistor on each output pin. This architecture allows the user to select the clock frequency range (from 40 kHz to 1600 kHz) that meets the requirements of their application and to choose between square wave duty cycles of 17% or 25%.

The device also has an integrated differential line driver interface that supports LVDS outputs. The LVDS mechanism supports data transmission at up to 5.5 Gbps, with a peak to peak differential voltage of up to 3.2 V. This makes the TFF11101HN/N1,118 suitable for applications that require high-speed data transfers.

The device is powered by a single +3.3V power supply, with an average quiescent current of just 10A and an 8-bit SPI/UART/I2C configuration interface. The outputs are available in both LVDS and non-LVDS types. The LVDS outputs are composed of groups of four outputs, for driving 16 LVDS output lines in total.

The TFF11101HN/N1,118 is compatible with a range of standard clocks and is suitable for use in a variety of different applications. It is often used in telecom and datacom networks, embedded industrial automation, mobile phone, and home entertainment systems. It is also used in high-end digital cameras and video surveillance systems.

The working principle of the TFF11101HN/N1,118 is relatively simple. It is based on a digitally-controlled oscillator (DCO) which, when powered up, starts a state machine which allows it to be configured for the chosen output clock rate. The DCO is programmed using the 8-bit SPI/I2C/UART port, allowing the device to be quickly configured for the desired output frequencies.

Once the DCO is configured, it passes the clock information to the SPMT output logic, which buffers the clock signals and sends the appropriate waveforms to the LVDS and non-LVDS outputs. This allows a single DCS device to quickly configure up to sixteen outputs for driving signals for LVDS and non-LVDS applications.

In summary, the TFF11101HN/N1,118 is an efficient and reliable clock/timing device that is suitable for clock and timing applications that require high performance and flexibility. Its LVDS interface facilitates fast data transmission, and its versatile 8-bit configuration port makes it suitable for a wide range of applications. It can be used in a variety of industries, including telecom, datacom, industrial automation, and home entertainment.
