SAA7715AH

The SAA7715AH is designed as one kind of cost effective and powerful high performance 24-bit programmable DSP SAA7715AH that integrates a 24-bit DSP core with programmable memories (program RAM/ROM, data and coefficient RAM), 4 digital serial inputs, 4 digital serial outputs, 2 separate SPDIF receivers, a stereo FSDAC, a standard Philips I2C-bus interface, a phase-locked loop for the DSP clock generation and a second phase-locked loop for system clock generation (internal and external DAC clocks).

Features of the SAA7715AH are:(1)One stereo bitstream DAC (2 channels) with 64 fold oversampling and noise shaping; (2)Selectable clock output (pin SYSCLK) for external slave devices (128fs to 512fs); (3)Four stereo digital serial outputs (8 channels) with selectable I2S-bus or LSB-justified format; (4)Two SPDIF inputs combined with digital serial input; (5)On-board WS_PLL generates clock for on-board DAC and output pin SYSCLK; (6)I2C-bus controlled (including fast mode); (7)Programmable Phase-Locked Loop (PLL) derives the clock for the DSP from the CLK_IN input; (8)-40 to +85 °C operating temperature range; (9)Supply voltage only 3.3 V; (10)All digital inputs are tolerant for 5 V input levels; (11)Power-down mode for low current consumption in standby mode.etc.

The absolute maximum ratings of the SAA7715AH can be summarized as:(1)supply voltage: -0.5 to +3.6 V;(2)input voltage: -0.5 to +5.5 V;(3)input clamping diode current: ±10 mA;(4)output clamping diode current: ±20 mA;(5)output source or sink current: ±20 mA;(6)ambient temperature: -40 to +85 °C;(7)storage temperature: -65 to +125 °C;(8)ground supply voltage difference: 100 mV.
