Analog Inputs
LINL, LINR - Left and Right Channel Line Level Inputs, Pins 18(L), 16(L), 24(Q), 20(Q)
Line level input connections for the right and left channels.
MINL, MINR - Left and Right Channel Microphone Inputs, Pins 17(L), 15(L), 22(Q), 18(Q)
Microphone level input connections for the right and left channels.
Analog Outputs
LOUTR, LOUTL - Line Level Outputs, Pins 33(L), 32(L), 66(Q), 64(Q)
One pair of line level outputs are provided. The output level for right and left outputs can be
independently varied. These outputs can be muted.
HEADR, HEADL - Headphone Outputs, Pins 29(L), 31(L), 52(Q), 60(Q)
HEADR and HEADL are intended to drive a pair of headphones. Additional current drive,
along with an optional +3 dB of gain, ensures reasonable listening levels. These outputs can be
muted.
HEADC - Common Return for Headphone Outputs, Pin 30(L), 56(Q)
HEADC is the return path for large currents when driving headphones from the HEADR and
HEADL outputs. This pin is nominally at 2.1 V.
CMOUT - Common Mode Output, Pin 19(L), 31(Q)
Common mode voltage output. This signal may be used for level shifting the analog inputs. The
load on CMOUT must be DC only, with an impedance of not less than 10k
. CMOUT should
be bypassed with a 0.47
μ
F to AGND. CMOUT is nominally at +2.1V.
MOUT1, MOUT2 - Mono Speaker Outputs, Pins 28(L), 27(L), 45(Q), 43(Q)
Mono external loudspeaker differential output connections. The loudspeaker output is a mix of
left and right line outputs. Independent muting of the speaker is provided. MOUT1 and
MOUT2 output voltage is nominally at 2.1 V with no signal.
VREF - Voltage Reference Output, Pin 21(L), 33(Q)
The on-chip generated ADC/DAC reference voltage is brought out to this pin for decoupling
purposes. This output must be bypassed with a 10
μ
F capacitor in parallel with a 0.1
μ
F
capacitor to the adjacent AGND1 pin. No other external load may be connected to this output.
Digital Interface Signals
SDIN - Serial Data Input, Pin 1(L), 87(Q)
Audio data for the DACs and control information for all functions is presented to the CS4215
on this pin.
SDOUT - Serial Data Output, Pin 44(L), 85(Q)
Audio data from the ADCs and status information concerning all functions is written out by the
CS4215 onto this pin.
