Clock Source
• Single Power Supply:
Bus-Powered: 5 V, Typical (VBUS)
The PCM2704/5/6/7 is TI's single-chip USB stereo
Self-Powered: 3.3 V, Typical
audio DAC with USB-compliant full-speed protocol
• 16-Bit Delta-Sigma Stereo DAC
controller and S/PDIF. The USB-protocol controller
works with no software code, but USB descriptors
Analog Performance at 5 V (Bus-Powered),
can be modified in some parts (for example, vendor
3.3 V (Self-Powered):
ID/product ID) through the use of an external ROM
THD+N: 0.006% RL > 10 kΩ,
(PCM2704/6), SPI (PCM2705/7), or on request. (1)
Self-Powered
The PCM2704/5/6/7 employs SpAct™ architecture,
TI's unique system that recovers the audio clock from
THD+N: 0.025% RL = 32 Ω
USB packet data. On-chip analog PLLs with SpAct
SNR = 98 dB
enable playback with low clock jitter.
Dynamic Range: 98 dB
PO = 12 mW, RL = 32 Ω
Oversampling Digital Filter
Pass-Band Ripple = ±0.04 dB
Stop-Band Attenuation = –50 dB
Single-Ended Voltage Output
Analog LPF Included
• Multiple Functions:
Up to Eight Human Interface Device (HID)
Interfaces (Depending on Model and

The modification of the USB descriptor through external ROM
Settings)
or SPI must comply with USB-IF guidelines, and the vendor
ID must be your own ID as assigned by the USB-IF. The
Suspend Flag
descriptor also can be modified by changing a mask; contact
S/PDIF Out With SCMS
your representative for details.
