Deserializer Operation Mode
The operation of the deserializer is only dependent upon the
data received on the DSI data signal pair and the CKSI clock
signal pair. The following two sections describe the operation of
the deserializer under two distinct serializer source conditions.
References to the CKREF and STROBE signals refer to the sig-
nals associated with the serializer device used in generating the
serial data and clock signals that are inputs to the deserializer.
When operating in this mode the internal serializer circuitry is
disabled including the parallel data input buffers. If there is a
CKREF signal provided then the CKSO serial clock will continue
to transmit bit clocks. Upon device power-up (S1 or S2 = 1) all
deserializer output data pins will be driven low until valid data is
passed through the deserializer.
Deserializer Operation:
DIRI equals 0
(Serializer Source: CKREF equals STROBE)
When the DIRI signal is asserted LOW the device will be config-
ured as a deserializer. Data will be captured on the serial port
and deserialized through use of the bit clock sent with the data.
The word boundary is defined in the actual clock and data sig-
nal. Parallel data will be generated at the time the word bound-
ary is detected. The falling edge of CKP will occur
approximately 6 bit times after the next falling edge of CKSI.
The rising edge of CKP will go HIGH approximately 13 bit times
after CKP goes LOW. When no embedded word boundary
occurs then no pulse on CKP will be generated and CKP will
remain HIGH.
.
Deserializer Operation:
DIRI equals 0
(Serializer Source: CKREF does not equal STROBE)
The logical operation of the deserializer remains the same
regardless of if the CKREF is equal in frequency to the
STROBE or at a higher frequency than the STROBE. The
actual serial data stream presented to the deserializer will how-
ever be different because it will have non-valid data bits sent
between words. The duty cycle of CKP will vary based on the
ratio of the frequency of the CKREF signal to the STROBE sig-
nal. The frequency of the CKP signal will be equal to the
STROBE frequency. The falling edge of CKP will occur 6 bit
times after the data transition. The LOW time of the CKP signal
will be equal to (13 bit times) of the CKREF period. The CKP
HIGH time will be equal to STROBE period of the CKREF
period. Figure 5 is representative of a waveform that could be
seen when CKREF is not equal to STROBE. If CKREF was sig-
nificantly faster then additional non-valid data bits would occur
between data words.
