SRC4190 (1) 192kHz Stereo Asynchronous Sample Rate Converters

DESCRIPTION

The SRC4190 is an asynchronous sample rate converter designed for professional and broadcast audio applications. The SRC4190 combines a wide input-to-output sampling ratio with outstanding dynamic range and low distortion. Input and output serial ports support standard audio formats, as well as a Time Division Multiplexed (TDM) mode. Flexible audio interfaces allow the SRC4190 to connect to a wide range of audio data converters, digital audio receivers and transmitters, and digital signal processors. The SRC4190 is a standalone pin-programmed device, with control pins for mode, data format, mute, bypass, and low group delay functions. The SRC4190 may be operated from a single +3.3V power supply. A separate digital I/O supply (V IO) operates over the +1.65V to +3.6V supply range, allowing greater flexibility when interfacing to current and future generation signal processors and logic devices. The SRC4190 is available in a SSOP-28 package.

PIN DESCRIPTIONS (SRC4190) ELECTROSTATIC DISCHARGE SENSITIVITY This integrated circuit can be damaged by ESD. Texas Instru- ments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

www.ti.com PIN COMPATIBILITY WITH THE ANALOG DEVICES AD1895 AND AD1896 The SRC4190 is pin-and function-compatible with the AD1895 and AD1896 when observing the guidelines indicated in the following paragraphs. Power Supplies. To ensure compatibility, the VDD_IO and VDD_CORE supplies of the AD1895 and AD1896 must be set to +3.3V, while the V IO and VDD supplies of the SRC4190 must be set to +3.3V. Pin 1 connection. For the AD1895, pin 1 is a no connect (N.C.) pin. For the SRC4190, pin 1 functions as the low group delay selection input, and should not be left unconnected. Pin 1 must be connected to either digital ground or the V IO supply, dependent upon the desired group delay. Crystal Oscillator. The SRC4190 does not have an on-chip crystal oscillator. An external reference clock is required at the RCKI input (pin 2). Reference Clock Frequency. The reference clock input frequency for the SRC4190 must be no higher than 30 MHz, in order to match the master clock frequency specification of the AD1895 and AD1896. In addition, the SRC4190 does not support the 768f S reference clock rate. Master Mode Maximum Sampling Frequency. When the input or output ports are set to Master mode, the maximum sampling frequency must be limited to 96kHz in order to support the AD1895 and AD1896 specification. This is de- spite the fact that the SRC4190 supports a maximum sam- pling frequency of 212kHz in Master mode. The user should consider building an option into his or her design to support the higher sampling frequency of the SRC4190. Matched Phase Mode. Due to the internal architecture of the SRC4190, it does not require or support the matched phase mode of the AD1896. Given multiple SRC4190 de- vices, if all reference clock (RCKI) inputs are driven from the same clock source, the devices will be phase matched.
