The PCM2707PJT is a member of the Cirrus Logic family of audio converters. It combines an Analog-to-Digital (A/D) converter, a Digital-to-Analog (D/A) converter, and an onboard sample rate converter (SRC). This family of products offers a flexible, cost-effective solution for embedded audio applications that require integrated A/D and D/A functionality.

Specifically, the PCM2707PJT offers several key features including low distortion, low power, and low noise. It also provides mono and stereo audio paths, support for a wide range of sampling rates, and an analog dynamic range of 90 dB. In addition, the PCM2707PJT includes integrated controls for gain, volume, mute, and playback/record modes.

The PCM2707PJT is well suited for use in a wide range of audio applications. It can be used in automotive infotainment systems, entertainment systems, home theater systems, and portable media devices. It can also be used in multimedia PCs and laptops, televisions and other consumer-electronics equipment. It is also suitable for use in professional audio systems, such as recording consoles, mixing boards, and noise-cancelling systems.

The PCM2707PJT features an I²S digital audio interface for data communication with a host processor. It also has an integrated SRC for converting the digital audio from one sampling rate to another. The SRC has a selectable frequency range from 8kHz to 48kHz, and supports sample rates with a resolution of 8, 16, and 24 bits. In addition, the PCM2707PJT supports both single and dual-mode I²S configurations.

The PCM2707PJT also includes several analog I/O pins for connecting to an audio source, such as an audio codec or microphone. It has a two-channel analog input for recording, and a two-channel analog output for playback. Each channel has an independent mute, volume, and gain control. The gain control can be set from -14 dB to +12 dB. In addition, the PCM2707PJT includes a digital mute control and an automatic level control (ALC) feature.

The PCM2707PJT also includes an integrated clock generator which allows the user to select the sampling rate and bit resolution of the incoming audio data. The clock generator also has an integrated oscillator and an internal PLL which can generate a wide range of clock frequencies. The integrated PLL provides a high-frequency, low-jitter clock signal to ensure accurate audio/video synchronization.

The PCM2707PJT also includes an integrated programmable low-pass filter which can be used to reduce aliasing effects and to filter out unwanted noise. The low-pass filter has two selectable pathways, one for recording and one for playback. The programmable filter can be configured for a low-pass filter bandwidth ranging from 1 kHz to 30 kHz with a steepness of 24 dB/octave, or from 10 kHz to 50 kHz with a steepness of 12 dB/octave.

Finally, the PCM2707PJT also features an integrated 3.3V linear regulator, allowing it to be used in a wide variety of power supply voltage levels. The PCM2707PJT is available in a 32-pin QFN package, making it suitable for surface mount applications.

The PCM2707PJT is a versatile unit that provides flexibility, low cost and low power consumption, making it an ideal solution for a wide range of audio applications. With its low distortion, low noise, and wide dynamic range, the PCM2707PJT delivers outstanding performance.
