The DS1077LZ-60 is an oscillator/timer IC, a part of TI’s Sure Timer™ family, primarily used in a wide range of applications. It is an analog programmable timer/oscillator that integrates high performance voltage-controlled oscillator (VCO), precision temperature compensator, a wide operating temperature range and a power supply monitor, making it suitable in multiple applications. It is the result of TI carefully combining both analog and digital technology to provide the highest level of product flexibility.

The DS1077LZ-60 operates from temperatures ranging from -40°C to 125°C, making it suitable for applications in areas with extreme temperatures such as automotive, aerospace and industrial designs. Additionally, it is capable of programmability with an external DIP switch, making it flexible and suitable for various applications. There are two separate outputs for frequency control, allowing for synchronized operations.

The DS1077LZ-60 supports multiple frequency ranges from 1Hz to 100kHz, making it suitable for frequency generation, frequency detection and frequency synthesis. With the wide frequency range and the flexibility of programming, it adjusts in a variety of applications. It is capable of precision control at temperatures ranging from -40°C to 125°C without any trimming, and also has a power supply monitor (PSM) to detect power supply voltage. In addition, a low power-down mode is available which can help minimize current consumption for mobile applications.

The DS1077LZ-60 has various application fields such as automotive, aerospace, industrial and commercial applications. It is used in electronic systems as an oscillator/timer, in automotive systems for testing and monitoring, in aerospace applications for frequency generation and control, in industrial systems for frequency detection and synthesis, and in commercial applications for synchronization operations.

The working principle of the DS1077LZ-60 is simple. Its voltage-controlled oscillator (VCO) is used in conjunction with a programmable or non-programmable time base to generate one of several selectable output frequencies. The VCO output is adjusted using an external voltage level that is maintained within the device by an internal precision temperature compensator. The internal PSM constantly monitors the device power supply and will shut down if the supply falls out of the acceptable operating range. The device also has several low power-down modes that reduce the operating current to less than 1µA when the device is not in use.

In summary, the DS1077LZ-60 is a highly versatile oscillator/timer IC. It is compatible with a wide variety of applications, from automotive to aerospace, from industrial to commercial. The flexible programming and precision temperature compensator allow it to maintain its accuracy over a wide temperature range, making it suitable for extreme temperature applications. The voltage-controlled oscillator and integrated power supply monitor, as well as the low power-down mode, add to its flexibility. All these features make the DS107LZ-60 a great choice for high-performance timing applications.
