Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The PCS3P2537AG-08CR is a thermo-compensated, miniature low-voltage Crystal Oscillator (LVCXO) specifically designed for use in high reliability, high performance RF/Wireless designs. It provides exceptional frequency stability over wide temperature range of -40°C to +85°C.

Application Field and Working Principle

The PCS3P2537AG-08CR has a wide range of application fields, such as Bluetooth and Wi-Fi radio frequency transceivers, Base station/Handset amplifiers and switches, and many more. This generator is particularly suitable for applications in low voltage supply components that require truncated operating frequency, low jitter and reduced temperature fluctuations. The PCS3P2537AG-08CR is capable of operating with supply voltage from 1.8VDD to 3.3VDD, with frequencies up to 132MHz.

The PCS3P2537AG-08CR clock generator works on the principle of a quartz crystal. It comprises of a quartz crystal that is placed between two metallic plates. When the voltage is applied to the plates, the quartz crystal vibrates at a constant frequency which is determined by the mass and surface area of the quartz crystal. This frequency is then used to generate the required output frequency.

The PCS3P2537AG-08CR uses a novel thermo-compensation design that minimizes the effect of temperature variations on the oscillator. It employs an additional temperature sensor in the quartz crystal that is used to measure the temperature of the crystal, and the output frequency is then adjusted accordingly. The result is a very accurate time base with exceptional frequency stability over a wide temperature range.

The PCS3P2537AG-08CR also has a high output amplitude, which eliminates the need for additional power for clock distribution. It also has the ability to provide a wide range of output drive levels, with a full scale current range from 2 milliamps to 15 milliamps. The wide range of output drive levels makes this clock generator ideal for use in applications that require high frequency stability and accuracy, such as wireless base station and hand held device applications.

The PCS3P2537AG-08CR offers long term frequency stability and is ideal for any application where accuracy is paramount. It is highly reliable and offers outstanding performance in a small package. It is an ideal solution for applications requiring frequency stability and accuracy over a wide temperature range.
