8.4 Data Input and Output
8.4.1 Bi-phase mark modulated digital data input (RXIN)
RXIN is an input pin for bi-phase mark modulated digital data.
The RXIN pin supports TTL levels. This allows a 5V-optical reception module to be connected directly.
8.4.2 Setting the bi-phase mark modulated input data reception range
The LC89052T allows the user to set the upper limit sampling frequency of the receivable input data and can receive
input data of specific sampling frequencies.
These are set with FLIMIT and FSSEL[3:0].
However, this function does not work in modes where the reception range is not limited with the FLIMIT.

The notation 32kHz to 96kHz means 32k, 44.1k, 48k, 64k, 88.2k, or 96kHz.
The table above only applies when the input fs calculation mode (FS4XIN) is set to "0". When FS4XIN is set to "1",
input data reception range is doubled.
Input data out of the set range is treated as an error, in which case the XIN source clock is output. At this time, the
DATAO output data is subject to the RDTSEL setting.
When the PLL follows a source with a variable fs, such as a CD player with variable pitch control, from the state
where the oscillator amplifier is stopped while PLL is locked, the fs is not calculated. As a result, an input frequency
not within the set range is not regarded as an error. The oscillator amplifier must be set to a continuous operation
mode to support such sources.
The reception range of input data can not be limited when setting up a system where no oscillator is required as XIN
and CKOUT are connected, because fs calculation is impossible in that case.
