DESCRIPTION

Output

Status signal output. Indicates a TRS error or a mismatch

between the embedded TRS and the flywheel TRS when the

flywheel is enabled. This signal is set high when an error in the

EAV TRS is detected or when the internal flywheel indicates

there is a mismatching EAV TRS. Refer to Fig. 3 for timing

information of EAV_ERR relative to LUMA (DATA_OUT[19:10])

and CHROMA (DATA_OUT [9:0]).

TEST Test pin. Used for test purposes only. This pin must be

connected to GND for normal operation.

N/A Must be connected to VDD for normal operation.

Input

Must be connected to GND for normal operation.

Input data bus. DATA_IN [19] is the MSB of the signal (pin 103).

DATA_IN [0] is the LSB of the signal (pin 126).

This data is typically scrambled and not word aligned.

DETAILED DESCRIPTION

1. DATA INPUT AND OUTPUTS

Data enters and exits the device on the rising edge of

PCLK_IN as shown in Figures 1 and 2. This data can be

scrambled or unscrambled and framed or unframed.

2. DESCRAMBLER AND FRAMER

Both the descrambler and framer can be enabled or

disabled independently of each other to allow the input to

remain scrambled or unscrambled. If the data is

unscrambled, it can be word aligned (framed) or passed

through unaltered.

3. STANDARDS INDICATION

VD_STD[3:0] indicates the standard that the device has

detected. The states of VD_STD[3:0] are shown in the

following standards indication tables.
