8 / 28 page AD1846 REV. A –8– Analog Signals Pin Name PLCC I/O Description L_LINE 30 I Left Line Input. Line level input for the left channel. R_LINE 27 I Right Line Input. Line level input for the right channel. L_MIC 29 I Left Microphone Input. Microphone input for the left channel. This signal can be ei- ther line level or –20 dB from line level. R_MIC 28 I Right Microphone Input. Microphone input for the right channel. This signal can be either line level or –20 dB from line level. L_AUX1 39 I Left Auxiliary #1 Line Input R_AUX1 42 I Right Auxiliary #1 Line Input L_AUX2 38 I Left Auxiliary #2 Line Input R_AUX2 43 I Right Auxiliary #2 Line Input L_OUT 40 O Left Line Level Output R_OUT 41 O Right Line Level Output Miscellaneous Pin Name PLCC I/O Description XTAL1I 17 I 24.576 MHz Crystal #1 Input XTAL1O 18 O 24.576 MHz Crystal #1 Output XTAL2I 21 I 16.9344 MHz Crystal #2 Input XTAL2O 22 O 16.9344 MHz Crystal #2 Output PWRDWN 23 I Power-Down Signal. Active LO control places AD1846 in its lowest power consump- tion mode. All sections of the AD1846, including the digital interface, are shut down and consume minimal power. INT 57 O Host Interrupt Pin. This signal is used to notify the host that the DMA Current Count Register has underflowed. XCTL1:O 56 & 58 O External Control. These signals reflect the current status of register bits inside the AD1846. They can be used for signaling or to control external logic. XLTL1 and XLTL0 are open-drain outputs. VREF 32 O Voltage Reference. Nominal 2.25 volt reference available externally for dc-coupling and level-shifting. VREF should not be used where it will sink or source current. VREF_F 33 I Voltage Reference Filter. Voltage reference filter point for external bypassing only. L_FILT 31 I Left Channel Filter Input. This pin requires a 1.0 µF capacitor to analog ground for proper operation. R_FILT 26 I Right Channel Filter Input. This pin requires a 1.0 µF capacitor to analog ground for proper operation. NC 46–52, 55 No Connect. Do not connect. Power Supplies Pin Name PLCC I/O Description VCC 35 & 36 I Analog Supply Voltage (+5 V) GNDA 34 & 37 I Analog Ground VDD 1, 7, 15, 19, I Digital Supply Voltage (+5 V) 24, 45, 54 GNDD 2, 8, 16, 20, I Digital Ground 25, 44, 53, 64 |
