TS220F23IET Application Field and Working Principle

TS220F23IET is an active load based on a monolithic integrated circuit especially designed for AT-cut anti-phase vibrator of quartz crystals. It\'s extremely useful for crystal application fields and typically clarifies the working principle of this active load.

TS220F23IET allows for Auto-Adjustment load adaption, allowing the circuit to precisely control the load to maintain the anti-phase oscillation.In addition, the Anti-phase autocompensation ensures the frequency of quartz crystal is stable and not influenced by the load, offering higher stability in the application field.The TS220F23IET also comes with an automatic insertion lock (AIL) function, which provides an additional layer of protection. This function blocks the insertion of an incorrect Load.Furthermore, the circuit comes with a power-on reset function which can reset the circuit when a power-on test is conducted, offering an improved reliability in the application field.

The working principle of TS220F23IET is based on active load control which consists of two integrated parts, namely the current source and the voltage regulator. The current source is responsible for drawing the current from the oscillating crystal and the voltage regulator is responsible for keeping the output voltage constant. This combination is able to precisely control the load current to maintain the oscillation of the quartz crystal and make sure the frequency is stable and not influenced by the load.

In addition to the anti-phase oscillation, the current source and voltage regulator can also maintain a constant frequency even in cases of load variations. This allows for a stable frequency in the application field regardless of load variations.

In summary, the TS220F23IET is an extremely useful active load based on a monolithic integrated circuit intended for AT-cut anti-phase vibrator of quartz crystals. It offers Auto-Adjustment load adaption, Anti-phase autocompensation, an automatic insertion lock (AIL) function, and a power-on reset function. Its working principle is based on active load controlling, which consists of two integrated parts, a current source and a voltage regulator which allow to precisely control the load current and maintain the oscillation of the quartz crystal while ensuring a stable frequency in the application field.
