The DS4000ECN/WBGA is a programmable timing and oscillator from Texas Instruments. It is part of the Clock/Timing family, under the Programmable Timers and Oscillators category. The product is engineered for use in device or system level timing applications and is said to be variously adaptable in terms of use.

The main features of the DS4000ECN/WBGA make it a particularly desirable option for many users. For starters, it has a frequency range of about 1 kHz to 100 MHz. In addition, the jitter of the device ranges between 150 fs (0.15 ps) and 400 fs (0.4ps), depending on the crystal used. The jitter optimal quality at frequencies of up to 12 MHz is said to be even better.

The device is said to incorporate a range of improved technologies and components, such as reduced power consumption of around 115 mW, a low-offset amplifier type X2Y, an on-board control loop, an active element cooling system, and an I/O storage capacity of up to 64 bits. Of course, the improved performance as compared to other programmable timer/oscillator products also adds to its appeal.

In terms of working principle, the DS4000ECN/WBGA basically works on the basis of a voltage-controlled oscillator (VCO) integrated into the system. The VCO consists of several elements, such as a BJT (bipolar junction transistor) and resistor network. The components in the VCO are connected to a signal source that supplies a DC bias voltage. The signal source control the signal output from the VCO, and this process of controlling signal source with signal output is known as feedback.

The signal output from the VCO is then converted to an analog frequency signal output. This signal is then further amplified into a digital frequency output through the device’s clock circuitry. The digital output is used to control the frequency of the signal source, and thus regulates the VCO.

The DS4000ECN/WBGA must be programmed to accurately calculate the desired frequency output, and this is done by programming the device with the help of special software. Once programmed, the device automatically configures itself to generate the necessary output according to the programmed parameters. The parameters are generally divided into three sections, namely start-up count, prescaler, and frequency. The start-up count serves to configure the device for the desired frequency output at the start of operation. The prescaler is used to divide the frequency input from the signal source by a desired value. Lastly, the frequency section is responsible for controlling the signal source frequency, thereby regulating the output from the device.

Apart from the basic working principle, the device is equipped with a variety of other features to aid in its usage. These features include: synchronization of signals from multiple devices, programmable settings and preset frequencies, and the ability to monitor and manage signals from the device with the help of a compatible Texas Instruments Real-Time WatchDog Timer (RTWDT).

In summation, the DS4000ECN/WBGA is an excellent choice of clock/timing product within the programmable timers and oscillators category. This product offers impressive performance and integrates a variety of improved technologies that makes it ideal for many device/system level timing applications. The DS4000ECN/WBGA may also be conveniently programmed and managed by Texas Instruments’ Real-Time WatchDog Timer, making it all the more desirable.
