Part Number: PCM1808-Q1 Hi support team.
I received a inquiry from my customer regarding difference between Q1 and non-Q1.
I think that the difference is operating temperature range only, is it correct?
If it is incorrect, let me know about the difference…
Part Number: PCM1808-Q1 Hi,
Please tell me about the center voltage input range.
The data sheet describes a minimum of 0.2Vcc and a maximum of 0.8Vcc.
Is this the range of variation of the Vref voltage built into the IC?
If this is the case, then Vref…
Part Number: PCM1808-Q1 Other Parts Discussed in Thread: PCM1808 Hi,
I'm looking at PCM1808 and the internal antialiasing filter.
According to the datasheet the cutoff frequency for the LPF is 1.3MHz and the delta-sigma modulator is 64 times FS.
Does…
Part Number: PCM1808-Q1 Other Parts Discussed in Thread: PCM1808 Hi Team,
I use PCM1808 in slave mode. And input SCLK=256fs,BCK=64fs. If change sampling rate 48kHz to 44.1kHz (change SCLK 12.288MHz to 11.2896MHz too,)
･How many sec does it take from SCKI…
Part Number: PCM1808-Q1 Hi team,
Could you advise a definition of t(LRDO) Delay time, LRCK edge to DOUT valid in Figure 22?
I measured LRCK falling edge to DOUT and the waveform was like the Figure 21 below.
DOUT output at second BCK falling edge, while…
Part Number: PCM1808-Q1 Hi team,
I measured start up delay from system clock in to DOUT.
System clock : 12.288MHz
fs = 48kHz
It should be 1024*system clocks + 8960/fs = 186.78ms.
But the measured value is 197ms.
Could you advise what is this 10ms delta…
Part Number: PCM1808-Q1 Other Parts Discussed in Thread: PCM1808 Hi team,
I have a question about the data format of PCM1808 in FORMAT=Low setting below.
#1. How many BCLK cycles or DATA bits in 1 LRCK cycle?
#2. Does DOUT hold the last data value after…
Part Number: PCM1808-Q1 Hi team,
In Slave mode, what happens if BCK and LRCLK rise time and fall time do not meet 20ns? It is assumed that the other interface timings can be satisfied with a margin.
regards,
Part Number: PCM1808-Q1 Other Parts Discussed in Thread: PCM1808 , Hi team,
Is there test mode (debug or trimming purpose) in PCM1808?
I concern if it accidentally fall into that mode during operation.
regards,
Hello,
I have reviewed our internal databases and the ESD ratings for the PCM1808-Q1 are:
HBM: 3kV
CDM: 1kV
MM: 200V
The PCM1808-Q1 was not tested up to 4kV like the commercial product was. It passed up to 3kV without issue so there's a chance it may…
