DESCRIPTION
The STA020D is a monolithic CMOS device
which encodes and transmits audio data accord-
ing to the AES/EBU, IEC 958, S/PDIF, & EIAJ
CP-340 interface standards. It supports 96kHz
sample rate operation
The STA020D accepts audio and digital data
which is then multiplexed, encoded and driven
onto a cable.
The audio serial port is double buffered and ca-

The STA020D multiplexes the channel, user, and
validity data directly from serial input pins with
dedicated input pins for the most important chan-
nel status bits.

RST and CBL (TRNPT is low)
When RST goes low, the differential line drivers
are set to ground. In order to properly synchro-
nize the ST020 to the audio serial port, the trans-
mit timing counters, which include CBL, are not
enabled after RST goes high until eight and one
half SCK periods after reset is exited) of FSYNC.
When FSYNC is configured as a left/right signal
(all defined formats except 2), the counters and
CBL are not enabled until the right sample is be-
ing transmitted). This guarantees that channel A
is left and channel B is right as per the digital
audio interface specs.
As shown in Figure 4, channel block start output
(CBL), can assist in serially inputting the C, U and
V bits as CBL goes high one bit period before the
first bit of the preamble of the first sub-frame of
the channel status block is transmitted. This sub-
frame contains channel status byte 0, bit 0. CBL
returns low one bit period before the start of the
frame that contains bit 0 of channel status byte
16. CBL is not available when the CD subcode
port is enabled.
Figure 4 illustrates timing for stereo data input on
the audio port. Notice how CBL rises while the
right channel data (Right 0) is input, but the pre-
vious left channel (Left 0) is being transmitted as
the first sub-frame of the channel status block
(starting with preamble Z). The C, U, and V input
ports only need to be valid for a short period after
FSYNC changes. A sub-frame includes one
audio sample while a frame includes a stereo
pair. A channel status (C.S.) block contains 24
bytes of channel status and 384 audio samples
(or 192 stereo pairs, or frames, of samples).
Figure 4 shows the CUV ports as having left and
right bits (e.g. CUV0L, CUV0R). Since the C.S.
block is defined as 192 bits, or one bit per frame,
there are actually 2 C.S. blocks, one for channel
A (left) and one for channel B (right). When input-
ting stereo audio data, both blocks normally con-
tain the same information, so C0L and C0R from
the input port pin are both channel status bit 0 of
byte 0, which is defined as professional/con-
sumer. These first two bits from the port, C0L and
C0R, are logically OR’ed with the inverse PRO,
since PRO is a dedicated channel status pin de-
fined as C.S. bit 0.
Also, if in professional mode, C1, C6, C7 and C9
are dedicated C.S. pins. The inverse of C1 is logi-
cally OR’ed with channel status input ports bits
C1L and C1R. In similar fashion, C6, C7 and C9
are OR’ed with their respective input bits. Also,
the C bits in CUV128L and CUV128R are both
channel status block bit 128, which is bit 0 of
channel status byte 16.
