DAC Audio Decoder ES9038Q2M High Frequency and Low Phase Noise OCXO Support for PCM768KHz/DSD256/DOP128 with a 9V Switch Power

DAC Audio Decoder ES9038Q2M High Frequency and Low Phase Noise OCXO Support for PCM768KHz/DSD256/DOP128 with a 9V Switch Power

Features:
- Q2M38 is a DAC based on ES9038Q2M, dedicated to HDMI I2S interface.

- The built-in high-frequency low phase noise OCXO is used for input data reconstruction. Generally, femtosecond crystal oscillators such as CCHD950/575 have a phase noise performance of around -90dbc/Hz at 10HZ, while OCXO used in Q2M38 outperforms 108dbc/Hz at 10HZ. With the support of OCXO, the input signal is subjected to upsampling and resampling processing.

- The I/V conversion circuit and LPF filter are designed using fully discrete transistor circuits from mature foreign circuits. They operate in Class A mode, with a total of 4 channels of I/V and 2 channels of LPF. The final RCA socket output is provided with a specially designed positive and negative voltage regulator to provide power for this part of the circuit.

- The RCA output voltage of Q2M38 is up to 3.8V, which can achieve good results for low gain amplifier stages. The output voltage can also be lowered by pressing the front panel button. Built-in delay relay to prevent power on impact sound, and sound output will only occur after 10 seconds of power on.

- The input signal format supports PCM to 768KHZ, DSD native to DSD256 (DSD512 locking will be slower), and DOP to DOP128
- Size: 100 x 95 x 65mm

Note:
- The signal polarity of the HDMI interface is+-/+-/+-/+-. If it is not I2S of this polarity, the opposite phenomenon of sound channels will occur.

Package Included:
- 1 x DAC
- 1 x 9V Switch Power
