AD1893Low Cost SamplePort 16-Bit ASRC | Encoders, Decoders, Converters | 4 | Active | The AD1893 SamplePort is a fully digital, stereo Asynchronous Sample Rate Converter (ASRC) that solves sample rate interfacing and compatibility problems in digital audio equipment. The AD1893 is intended for 16-bit, low cost, non-varispeed applications where low voltage, low power operation is required. (Refer to theAD1890/AD1891data sheet for other products in the SamplePort family.) This device is asynchronous because the frequency and phase relationships between the input and output sample clocks (both are inputs to the AD1893 ASRC) are arbitrary and need not be related by a simple integer ratio. There is no need to explicitly select or program the input and output sample clock frequencies, as the AD1893 automatically senses the relationship between the two clocks. The input and output sample clock frequencies can nominally range from 8 kHz to 56 kHz, and the ratio between them can vary from approximately 1:2 to 2:1.The input and output control signals allow for considerable flexibility for interfacing to a variety of DSP chips, AES/EBU receivers and transmitters and for I2S compatible devices. Input and output data can be independently right- or left- (with or without a one bit clock delay) justified to the left/right clock edge. In the right-justified mode, the MSB is delayed 16 bit clock periods from the left/right clock edge transition. Input and output data can also be independently justified to the word clock rising edge. The data justification options are encoded on two mode pins for both the input port and the output port.The AD1893 is fabricated in a 0.8 µm single poly, double metal CMOS process and are packaged in a 0.6" wide 28-pin plastic DIP and a 10 mm by 10 mm body size 44-pin TQFP. The AD1893 operates from a +3 V to +5 V power supply over the temperature range of 0°C to +70°C. |

AD19338-Channel DAC with PLL and Differential Outputs, 192 kHz, 24 Bits | Integrated Circuits (ICs) | 4 | Active | The AD1933 is a high performance, single chip that provides eight digital-to-analog converters (DACs) with differential output using the Analog Devices, Inc., patented multibit sigma- delta (Σ-Δ) architecture. An SPI port is included, allowing a microcontroller to adjust volume and many other parameters. The AD1933 operates from 3.3 V digital and analog supplies. The AD1933 is available in a 64-lead (differential output) LQFP. Other members of this family include a single-ended DAC output and I2C® control port version.The AD1933 is designed for low EMI. This consideration is apparent in both the system and circuit design architectures. By using the on-board PLL to derive the master clock from the LR clock or from an external crystal, the AD1933 eliminates the need for a separate high frequency master clock and can also be used with a suppressed bit clock. The DACs are designed using the latest Analog Devices continuous time architectures to further minimize EMI. By using 3.3 V supplies, power consumption is minimized, further reducing emissions.Applications:Automotive audio systemsHome Theater SystemsSet-top boxesDigital audio effects processors |
