This pin is used to bypass the on–chip V
DD
/2 voltage reference for the V
AG
output pin.
This pin should be bypassed to V
SS
with a 0.1
μ
F ceramic capacitor using short, low
inductance traces. The V
REF
pin is only used for generating the reference voltage for the
V
AG
pin. Nothing is to be connected to this pin except the bypass capacitor.
Inverting output of the receive smoothing filter. This pin can typically drive a 2k
Ω
load to
0.886V
PEAK
referenced to analog ground.
Inverting input to the power amplifier. The non-inverting input is tied internally to V
AG
voltage.
Inverting power amplifier output. The PAO- and PAO+ can drive a 300
Ω
load differentially
to 1.772V
PEAK
.
Non-inverting power amplifier output. The PAO- and PAO+ can drive a 300
Ω
load
differentially to 1.772V
PEAK
.
Power supply. Should be decoupled to V
SS
with a 0.1
μ
F ceramic capacitor.
8kHz Frame Sync input for the PCM receive section. FSR can be asynchronous to FST in
either Long Frame Sync or Short Frame Sync mode.
PCM input data receive pin. The data needs to be synchronous with the FSR and BCLKR
pins.
PCM receive bit clock input pin. Can accept any bit clock frequency from 256 to 4800kHz.
When not clocked it can be used to select the 16 sign-bit extended synchronous mode
(BCLKR=0) or the receive gain adjust synchronous mode (BCLKR=1)
Power up input signal. When this pin is tied to V
DD
, the part is powered up. When tied to
V
SS
, the part is powered down.
System master clock input. Possible input frequencies are 256kHz, 512kHz, 1536kHz,
1544kHz, 2048kHz, 2560kHz, 4096kHz & 4800kHz. For performance reasons, it is
recommended that MCLK be synchronous and aligned to the FST signal. This is a
requirement in the case of 256 and 512kHz frequencies.
PCM transmit bit clock input pin. Can accept any bit clock frequency from 256 to
4800kHz.
PCM output data transmit pin. The output data is synchronous with the FST and BCLKT
pins.
8kHz transmit frame sync input. This pin synchronizes the transmit data bytes.
This is the supply ground. This pin should be connected to 0V.
High-pass Bypass. Determines if the transmit high-pass filter is used (HB=’0’) or
bypassed (HB=’1’). When the high pass is bypassed the frequency response extends to
DC.
Inverting input of the first gain stage in the transmit path.
Non-inverting input of the first gain stage in the transmit path.
Mid-Supply analog ground pin, which supplies a V
DD
/2 volt reference voltage for all-
analog signal processing. This pin should be decoupled to V
SS
with a 0.01
μ
F capacitor.
This pin becomes high impedance when the chip is powered down.
