Working principle

The DS4077L-ECN uses a dual-channel, low-power oscillator topology to achieve its precision and accuracy. The core of the oscillator is a pair of cross-coupled differential transistor pairs with their output connected to an integrated resistor divider network. The resistor divider network consists of fixed resistors and a variable resistor. The variable resistor can be adjusted to change the frequency of the oscillator. The frequency of the oscillator is then determined by the ratio between the fixed resistor and the variable resistor.

The DS4077L-ECN also incorporates an auxiliary circuit, which allows the user to program the frequency of the oscillator. The auxiliary circuit consists of a voltage regulator and a pair of n-channel field-effect transistors (NFETs). The FETs are used to control the frequency of the oscillator by changing the voltage of the voltage regulator. By adjusting the voltage of the voltage regulator, the frequency of the oscillator can be precisely programmed to a customer requested frequency.

In addition to the auxiliary circuit, the DS4077L-ECN also includes an on-chip voltage detector that can detect power supply voltage variation. The voltage detector is used to ensure that the oscillator maintains its accuracy and precision even when the power supply voltage changes.
