The DAC34SH84 is a very low-power, high-dynamic range, quad-channel, 16-bit digital-to-analog converter (DAC) with a sample rate as high as 1.5 GSPS.

The device includes features that simplify the design of complex transmit architectures: 2× to 16× digital interpolation filters with over 90 dB of stop-band attenuation simplify the data interface and reconstruction filters. Independent complex mixers allow flexible carrier placement.

A high-performance low-jitter clock multiplier simplifies clocking of the device without significant impact on the dynamic range. The digital quadrature modulator correction (QMC) enables complete IQ compensation for gain, offset and phase between channels in direct upconversion applications.

Digital data is input to the device through a 32-bit wide LVDS data bus with on-chip termination. The wide bus allows the processing of high-bandwidth signals. The device includes a FIFO, data pattern checker, and parity test to ease the input interface. The interface also allows full synchronization of multiple devices.

The device is characterized for operation over the entire industrial temperature range of –40°C to 85°C and is available in a 196-ball, 12-mm × 12-mm, 0.8-mm pitch NFBGA package.

The DAC34SH84 low-power, high-bandwidth support, superior crosstalk, high dynamic range, and features are an ideal fit for next-generation communication systems.

TIDA-00072 — 寬頻數位至射頻發送解決方案

TSW308x 是寬頻數位至 RF 傳輸解決方案的設計範例,可產生 600MHz 連續 RF 頻譜。  系統示範了如何使用 DAC34x8x、TRF3705 IQ 調變器和 LMK0480x 來達成此目標。  此參考 EVM 結合模式發生器(例如 TSW1400EVM),可在 RF 下任意產生窄頻和寬頻訊號。  其中提供了產生符合標準 WCDMA 測試訊號的配置範例。

TIDA-00077 — 適用於 DAC348x 和調變器的類比介面網路

此參考設計中的類比介面電路通常用於電流來源型數位轉類比轉換器 (DAC) 和正交調變器之間。雖然 DAC348x 可作為 TI 高速 DAC 範例,但只要稍加修改,電路仍可套用至其他電流來源轉換器。預設情況下,DAC348x 和 TRF3705 類比介面會安裝在 TSW308xEVM 上。DAC348x 與 TRF3705 皆採用相同的 DC 偏壓與 AC 擺幅規格,以提供無縫的介面。介紹其他電路拓撲,以考慮其他 DC 偏壓與 AC 擺幅規格。透過計算正確的 DC 偏壓和適當的 AC 擺幅,系統設計人員可以根據其應用需求套用這些電路,以實現最佳性能。
