TSDP1808 - Octal PDM to 24-bit TDM Converter

General Description

The TSDP18xx is an ultra low-power, high-performance, 8 channel PDM to Linear PCM converter.

It supports Digital MEMS Microphone (DMIC) over sample rates up to 6.144MHz; and output sampling rates of 8KHz up to 384KHz enabling support for Ultrasonic capable DMICs.

Key Features

  • High-Fidelity Octal PDM to Linear PCM Converter.
  • Internal processing takes place at the DMIC clock rate.
  • > 142dB SNR / DNR / THD+N Level (20Hz ~ 20kHz).
  • Output Fs supports 8kHz up to 384kHz.
  • Configurable DMIC fixed output clock, based on Fs of supplied LRCLK and specified oversampling mode.
  • Support for wide range of SLCK to LRCLK / FRMCLK ratios: 32x, 48x, 64x, 96x, 128x, 192x, 256x, 384x, and 512x with automatic detection of SCLK.

® Tempo Semiconductor, Inc. OCTAL PDM TO 24-BIT TDM CONVERTER Data Sheet TSDP18xx GENERAL DESCRIPTION The TSDP18xx is an ultra low-power, high-performance, 8 channel PDM to Linear PCM converter. It supports Digital MEMS Microphone (DMIC) over sample rates up to 6.144MHz; and output sampling rates of 8KHz up to 384KHz enabling support for Ultrasonic capable DMICs. TSDP18xx supports 2 channel I2S or Left-Justified (LJ) format output as well as up to 8 channels using the Time-Division Multiplexed (TDM) format. The device enables a wide variety of configurations 32-bit, 24-bit or 16-bit word lengths, clock polarity inversion, and more to maximize compatibility with almost any DSP, Audio Processor, Codec or SOC.
