CDB4362A屬于開發(fā)板套件編程器的評估板-數(shù)模轉(zhuǎn)換器（DAC）。由凌云邏輯制造生產(chǎn)的CDB4362A評估板 - 數(shù)模轉(zhuǎn)換器（DAC）該系列產(chǎn)品提供了一種方便的方法，在經(jīng)過驗證的設(shè)計環(huán)境中對用于將數(shù)字?jǐn)?shù)據(jù)轉(zhuǎn)換為模擬格式的器件進行性能或特性評估。重點器件涵蓋范圍從以適合學(xué)生或愛好者使用的方式實現(xiàn)的適度功能器件，到適合電信基礎(chǔ)設(shè)施應(yīng)用的高級器件。

描述 Description

The CS4362A is a complete 6-channel digital-to-analog system. This D/A system includes digital de-emphasis, one-dB step size volume control, ATAPI channel mixing, selectable fast and slow digital interpolation filters followed by an oversampled, multi-bit delta sigma modulator which includes mismatch shaping technology that eliminates distortion due to capacitor mismatch. Following this stage is a multi-element switched capacitor stage and low-pass filter with differential analog outputs.

The CS4362A also has a proprietary DSD processor which allows for 50 kHz on-chip filtering without an intermediate decimation stage.

The CS4362A accepts PCM data at sample rates from 4 kHz to 216 kHz, DSD audio data, and delivers excellent sound quality. These features are ideal for multichannel audio systems including SACD players, A/V receivers, digital TV’s, mixing consoles, effects processors, sound cards and automotive audio systems.
