The PCM510x – THD+N: - 93/-92/90dB @ - 1dBfs (Typical) uses the latest generation of TI ’s advanced segment DAC architecture to achieve excellent dynamic – Full Scale Output: 2.1VRMS (Ground Center) performance and improved tolerance to clock jitter. – No DC Blocking Capacitors Required The PCM510x devices are simpler hardware – Market leading low out of band noise. controlled 2VRMS DACs, with filter select, PLL and • Digital Filter Latency & Performance Select auto-mute functions. • Normal 8 × Oversampling Digital Filter: The PCM510x provides 2.1VRMS ground centered – Stopband Attenuation: –60dB outputs, allowing designers to eliminate DC blocking – Passband Ripple: ±0.02dB capacitors on the output, as well as external muting • Low Latency 8 × Oversampling Digital Filter: circuits traditionally associated with single supply line – Stopband Attenuation: –52dB drivers. – Passband Ripple: ±0.0001dB The integrated line driver surpasses all other • Sampling Frequency: 8kHz To 384kHz charge-pump based line drivers by supporting loads • System Clock Multiples (fSCK): 64, 128, 192, down to 1k Ω. 256, 384, 512, 768, 1024, 1152, 1536, 2048, 3072 By supporting loads down to 1k Ω, the PCM510x can • Accepts 16-, 24-, And 32-Bit Audio Data essentially drive up to 10 products in parallel. (LCD • PCM Data Formats: I2s, Left-Justified TV, DVDR, AV Receivers etc). • Intelligent Muting System, Soft Up/Down Ramp The integrated PLL on the device removes the & Analog Mute For 120dB Mute SNR With requirement for a system clock (commonly known as Popless Operation. master clock). This allows a 3-wire I2S connection, • Integrated Power On Reset along with reduced system EMI. • Integrated Negative Charge Pump Intelligent clock error and PowerSense under voltage • Integrated High-Performance Audio PLL With protection utilizes a two level mute system for BCK Reference To Generate SCK Internally pop-free performance. Upon clock error or system • Automatic Power-Save Mode When LRCK And power failure, the device digitally attenuates the data BCK Are Deactivated. (or last known good data), then mutes the analog circuit • Internal Pop-Free Control For Sample-Rate Changes Or Clock Halts Compared with existing DAC technology, the • Single Supply Operation: PCM510x family offers up to 20dB lower out-of-band – 3.3V Analog, 3.3V Digital noise, reducing EMI and aliasing in downstream amplifiers/ADCs. (from traditional 100kHz OBN • 3.3V Failsafe LVCMOS Digital Inputs measurements all the way to 3MHz) • Small 20-pin TSSOP Package The PCM510x accepts industry-standard audio data APPLICATIONS formats with 16- to 32-bit data. Sampling rates up to 384kHz are supported. • A/V Receivers • DVD, BD Players • HDTV Receivers • Other Applications Requiring 2Vrms output 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 System Two Cascade, Audio Precision are trademarks of Audio Precision. 3 DirectPath is a trademark of Texas, Instruments, Inc..
