The 98ULPA877AHLFT IC operates with an operating voltage of 3.5V or 5V, with both power and ground “on”. This IC is a high performance, low power, single-channel clock/timing – application specific device which consists of oscillator, counter, and data registers. With its wide range of features and operation modes, it can provide reliable performance for many clock/timing application needs.

The clock/timing application that the 98ULPA877AHLFT is designed for is oscillator-driven designs, typically used in timing applications such as frequency multipliers, CPU/PowerPC synchronization, and system clocks. The main function of these oscillator-driven designs is to create accurate frequency reference clocks which can, in turn, be used to synchronize the system’s communication interface and/or application. With the 98ULPA877AHLFT, the oscillator reference clock can be generated in a wide range of frequencies and with accuracy rates up to two percent.

The 98ULPA877AHLFT operates in two main operating modes: synchronous and asynchronous. In synchronous mode, the device functions in a manner similar to a digital frequency multiplier, which can multiply an external clock signal to achieve a higher frequency output. In this mode, the IC’s internal oscillator is used to produce the multiplied output clock. In asynchronous mode, the device functions as a simple digital frequency divider, which can divide an external clock signal by a configurable factor (up to four). In this mode, the IC’s internal divider is used to produce the divided output clock.

In addition to these main operating modes, the IC can also be used as an external loopbreaker generator, enabling a synchronized point-to-point communication line. In this mode, the IC will generate an signal indicating when the communication line should be broken, allowing the external loopbreaker signal to be shut off without affecting other components in the communication line.

The IC includes a variety of configurable parameters which can be used to tailor the device to a specific application. For example, the device can be configured to produce an output clock signal with a frequency anywhere from 1 Hz to 1 MHz (also configurable). Additionally, a wide range of resistance and capacitance values can be used to adjust the performance of the output clock signal.

The 98ULPA877AHLFT can also be used for its internal 32-bit register capability, allowing for the storage of data which can be accessed later by other components. This can be used to store configuration/calibration information, as well as other data which could be used in a clock/timing application.

Overall, the 98ULPA877AHLFT IC is a low-power, single channel clock/timing – application specific IC. With its wide range of features and operation modes, it can provide reliability and accuracy in many clock/timing applications. The device can be customized to meet specific application needs using its various configurable parameters and can provide valuable data storage capabilities as well.
