Description
The CRD44600-PH-FB PWM Amplifier demonstrates the CS44600, Cirrus’ multi-channel pure digital PWM controller. This reference design implements a twochannel amplifier which delivers 100 W per full-bridge channel into 8 Ω loads using a single +50 V supply (at 1% THD+N). A 155 W unregulated linear power supply is used to power the CRD44600-PH-FB.
As shown below, the CS44600 IC takes two stereo digital audio PCM inputs and converts them to PWM outputs. This 64-pin LQFP PWM controller provides an integrated sample rate converter for 32 kHz-192 kHz input sample rate support, volume up/down, speaker load compensation, peak limiting to prevent amplifier clipping, power supply ripple compensation, and AM frequency interference elimination.
This reference design uses the the Philips TDA8939, an integrated power stage back end for digital amplifiers (two TDA8939 parts configured as full-bridges are used for this two-channel design). Current limiting and thermal protection are provided by the TDA8939.
The inductor/capacitor 2nd order low pass filter (LPF) removes high frequency components from the output signal effectively converting it from digital to analog.

General Description
The CS42418 codec provides two analog-to-digital and eight digital-to-analog delta-sigma converters, as well as an integrated PLL.
The CS42418 integrated PLL provides a low-jitter system clock. The internal stereo ADC is capable of independent channel gain control for single-ended or differential analog inputs. All eight channels of DAC provide digital volume control and differential analog outputs. The general-purpose outputs may be driven high or low, or mapped to a variety of DAC mute controls or ADC overflow indicators.
The CS42418 is ideal for audio systems requiring wide dynamic range, negligible distortion and low noise, such as A/V receivers, DVD receivers, digital speaker and automotive audio systems.

Description
 The CS5460A is a highly integrated power measurement solution which combines two ∆Σ
Analog-to-Digital Converters (ADCs), high speed power calculation functions, and a serial interface on a single chip.
It is designed to accurately measure and calculate: Real (True) Energy, Instantaneous Power, IRMS, and VRMS for single phase 2- or 3-wire power metering applications.
The CS5460A interfaces to a low-cost shunt resistor or transformer to measure current, and to a resistive divider or potential transformer to measure voltage.
The CS5460A features a bi*directional serial interface for communication with a micro-controller and a pulse output engine for which the average pulse frequency is proportional to the real power.
The CS5460A has on-chip functionality to facilitate AC or DC system-level calibration.
The “Auto-Boot” feature allows the CS5460A to function ‘stand-alone’ and to initialize itself on system power-up.
In Auto-Boot Mode, the CS5460A reads the calibration data and start-up instructions from an external EEPROM.
In this mode, the CS5460A can operate without a microcontroller, in order to lower the total bill-of-materials cost.
