ALD4501PEL

The ALD4501PEL is a Programmable Timers and Oscillators from NXP Semiconductors. It consists of three timer devices, two MicroTimers and cmos version of the IDT70000 series Programmable Timers and Oscillators. It is designed to meet the needs of advanced communications applications in both time domain (e.g. packet networks) and frequency domain (e.g. trapezoidal waveforms).

The ALD4501PEL is a low power, moderate performance solution that provides a complete or partial timing solution to any network based product in terms of low frequency controlled timing. It is used to synchronize time-domain operations and frequency-domain operations of tasks. It is designed to offer a rich set of features for applications requiring precise timing and synchronization.

The ALD4501PEL is an asynchronous programmable timer that offers an easily configurable timer with an open loop timer resolution from 10µs to 90 minutes. It provides five trigger inputs that allow the ALD4501PEL to combine external events with its counter to produce a precise and precise control of various process times. The ALD4501PEL also features a two-way serial digital configuration port for direct programming, as well as an analog input for automatic configuration.

The ALD4501PEL has a wide range of clock sources and outputs that can be linked to the system clock. This allows flexible timing options for the user. It provides flexible period and duty cycle ratios, programmable dead-time and pre-shifted pulse timing, low frequency pulse output and LED flasher capabilities. It also offers a variety of programmable trigger functions, which can be programmed directly via the serial port.

The working principle of the ALD4501PEL is based on the timer and oscillator functions integrated into the device. With the rich set of configurable options, it can be used to implement various timing applications. It uses two MicroTimers for frequency and time domain synchronization and its cmos version of the IDT70000 series Programmable Timers and Oscillators for frequency and period control. The timer is programmed to produce the desired frequency output, then the MicroTimer is triggered to start the counter based on the programmed value. The MicroTimer send a signal to the timer when the MicroTimer reaches the predetermined count value. The timer sends a control signal back to the MicroTimer to control its count.

The ALD4501PEL can be used in a wide variety of applications such as wireless communications, local area networks, cable converter boxes, and broadcasting equipment. Its flexible programming and ease of use makes it ideal for these applications. It\'s also well suited for applications requiring precise timing and synchronization, such as packet networks, switchers, or other communication systems.

In summary, the ALD4501PEL Programmable Timers and Oscillators from NXP Semiconductors offers a complete and powerful solution to any timing or synchronization requirements. Its wide range of clock sources, outputs, and programmable trigger functions, makes it an ideal choice for advanced communications applications. Its low-power, moderate performance and ease of use makes it an ideal solution for any network-based product in terms of low frequency controlled timing.
