DSPB56362AG120 - 24-bit Audio DSP, 120MHz, 144-LQFP | NXP
MPN: DSPB56362AG120 ⚠ Lần mua cuốiDSPB56362AG120 Tóm tắt
An audio DSP is a specialized microprocessor optimized for real-time numeric computation on streaming sample data. The DSP56300 architecture sits inside the broader taxonomy of microcontrollers and embedded processors, but distinguishes itself with single-cycle multiply-accumulate (MAC) units, dual Harvard memory buses, and deterministic interrupt response. Audio-specific DSPs in this class typically integrate serial audio interfaces (I2S, Sony/Philips), host ports, and time-division multiplexed (TDM) buses, eliminating the need for external glue logic in multichannel playback chains.
Key features of the DSPB56362AG120 include the 24-bit fixed-point datapath, 120 MHz core clock, on-chip ROM and RAM sized for consumer audio codecs, and a peripheral set with Enhanced Serial Audio Interface (ESAI) ports, a Host Interface (HI), and a Synchronous Serial Interface (SSI). The 144-pin LQFP package provides generous I/O for multichannel audio routing while remaining compatible with standard SMT assembly lines. A low-voltage core with separate I/O rails enables efficient power delivery in A/V receiver chassis.
Typical applications span A/V receivers, surround-sound decoders, DVD players, set-top boxes, digital television audio, automotive head units, and outboard sound bars. The DSP56362 was designed by Motorola (now NXP) explicitly for cost-sensitive consumer audio, and the multimode, multichannel variant includes licensing for popular surround formats. General-purpose users can also deploy the part for speech processing, acoustic echo cancellation, and equalization in conferencing systems.
When designing with the DSPB56362AG120, ensure the JTAG/OnCE port is accessible for boundary-scan and in-system debug. The 3.3V I/O and 1.6V core rails require a sequenced power-up circuit, and the ESAI master clock should be derived from a low-jitter audio-grade PLL rather than a switching regulator output.

Ứng dụng tiêu biểu
DSPB56362AG120 phù hợp cho 6 Áp dụngs: A/V Receiver Audio Decoding, Surround-Sound Soundbar Processor, DVD / Blu-ray Player Audio Engine, Automotive Head Unit Audio DSP, Digital TV Audio Subsystem, Conferencing System Acoustic Processing.
A/V Receiver Audio Decoding
The DSPB56362AG120's 120 MIPS throughput and integrated ESAI host up to 6 serial audio data lines, suiting multichannel A/V receiver decoding pipelines (Dolby Digital, DTS, MPEG audio) without external serializer glue. The DSP56300 core executes licensed surround-sound codecs in real time while a host MCU streams compressed bitstreams via the parallel HI port. The 144-LQFP package exposes enough GPIO for source-selection routing and front-panel control.
Được đề xuất
Surround-Sound Soundbar Processor
Single-chip cost-optimized surround processing for soundbar designs benefits from the DSPB56362AG120's on-chip codec licensing and 24-bit fixed-point MAC pipeline, which handles psychoacoustic virtualization (virtual surround) within a 120 MIPS budget. ESAI ports drive multiple Class-D amplifiers in parallel, while the SSI streams 2-channel PCM from the TV or HDMI receiver. The 3.3V I/O and 1.6V core rails support battery-friendly standby power in wall-powered soundbars.
Được đề xuất
DVD / Blu-ray Player Audio Engine
DVD and Blu-ray players benefit from the DSPB56362AG120's combination of licensed audio codecs and a deterministic DSP56300 interrupt model that maintains lip-sync during disc playback. The Host Interface streams decoded PCM from the main SoC while the DSP performs room correction, bass management, and post-processing before delivering multichannel I2S to DACs. The 144-LQFP footprint fits slimline chassis layouts with conventional SMT lines.
Được đề xuất
Automotive Head Unit Audio DSP
In automotive head units, the DSPB56362AG120's DSP56300 core delivers 120 MIPS sufficient for ANC (active noise cancellation), road-noise compensation, and cabin-tuned equalization in real time. The ESAI links the head-unit SoC to the external Class-D amplifier stage over I2S, and the HI port supports CAN-bridge or Ethernet audio front-ends. Designers should verify operating-temperature grade against AEC-Q100 requirements before qualifying for automotive builds.
Được đề xuất
Digital TV Audio Subsystem
Integrated digital televisions use the DSPB56362AG120 to decode broadcast audio formats (AC-3, MPEG-1 Layer 2/3) and apply virtualization on stereo speaker enclosures. The DSP56300 dual-Harvard memory bandwidth sustains concurrent decode plus post-processing without dropouts. ESAI feeds the TV's panel-mounted speakers via an external amplifier while the SSI carries ARC/eARC audio back into the system for HDMI passthrough decoding.
Được đề xuất
Conferencing System Acoustic Processing
Conference phones and beam-forming microphone arrays leverage the DSPB56362AG120's deterministic MAC pipeline for acoustic echo cancellation (AEC), noise suppression, and beam-forming across multiple microphone channels. ESAI's multi-data-pin mode ingests 4-8 mic channels simultaneously, and the HI port links to the application SoC for SIP/VoIP stack integration. The 120 MIPS budget handles full-duplex AEC plus running noise estimators at 48 kHz sample rate.

Ghi chú thiết kế
The DSPB56362AG120 requires two rails: 1.6V core and 3.3V I/O. Power sequencing is required (core first, then I/O) to prevent latch-up. Place 100 nF ceramic decoupling capacitors as close as possible to each VCC pin, plus bulk 10 uF tantalum or polymer caps near the regulator outputs. Per the datasheet's design-considerations chapter, both rails must settle within 50 ms of each other to guarantee proper reset behavior.
Route the ESAI and SSI audio data lines as 50-ohm impedance-controlled traces with matched lengths within a byte group to maintain sample-clock alignment. Keep ESD-protected areas away from the analog supply filter network. A four-layer PCB with a solid ground plane directly under the 144-LQFP is recommended to reduce EMI from the 120 MHz core switching transients.
Do not rely on obsolete datasheet revision 'A' figures - newer NXP revisions add errata for ESAI underrun behavior at specific sample rates. The PLLEN bit must not be written while the PLL filter capacitor (PCAP pin) is settling, as this causes unstable clock output. Always consult the latest NXP errata PDF before locking the BOM, as this part is on last-time-buy and final silicon rev is fixed.
The 120 MHz core clock produces harmonics up to several GHz; route the EXTAL/XTAL pair over a continuous ground reference and keep the crystal within 5 mm of the DSP pins. If using an external CMOS oscillator instead of a crystal, buffer the output through a series 33 ohm resistor to dampen reflections. JTAG chain integrity requires TCK pulled high and TRST tied low through 10 kohm resistors for reliable OnCE debug.
