FUNCTIONAL BLOCK DIAGRAM AND DESCRIPTION

Figure 1:  Functional Block Diagram 

HyperStream ADC

The Sabre ADC uses ESS’ patented Hyperstream architecture for performing super accurate analog-to-digital conversion.

The HyperStream ADC uses a hybrid combination of high-speed digital and precision analog circuits to sample and convert

the analog input signal. The oversampled signal is then passed to the digital core of the Sabre ADC for further processing.

Decimation Filter

A decimation filter structure is used to perform downsampling of the digital output from the HyperStream ADC. The purpose

of the decimation filter is to remove any high frequency data before downsampling the data to a lower sampling rate. The

decimation filter is a two stage FIR structure, and is fully programmable.

Programmable Filter

A fully programmable biquad filter is available after the decimation filter. The biquad filter structure contains eight full

biquads per channel, and is completely customizable, with up to 20dB of headroom in each biquad. The programmable filter

uses the RIAA filter by default, and can be reprogrammed using I

Serial Output Interface

Output data can be formatted to use either the SPDIF or the I

are available (including LJ, RJ and I

Control/Status Interface

The Sabre ADC is fully programmable using I

an external microcontroller.
