Description

[7:6]

SELECT_RAW_DATA_NUM

Whole number divide value + 1 for raw data clock

(SYS_CLK/divide_value). When SELECT_RAW_DATA_NUM

is larger than 0, the divided clock is not a 50% duty cycle

clock.

•

2'd0: Whole number divide value + 1 = 1 (default)

•

2'd1: Whole number divide value + 1 = 2

•

2'd2: Whole number divide value + 1 = 3

•

2'd3: Whole number divide value + 1 = 4

[5]

RAW_DATA_CLK_DIV2

Further divides the raw data clock by 2 (after divided by

SELECT_RAW_DATA_NUM+1) to create a 50% duty cycle

raw data clock.

•

1'b0: No divide (default)

•

1'b1: Further divides the raw data clock by 2

[4]

RAW_DATA_DDR

Enables raw data double-data-rate (DDR) output.

In the DDR mode, raw data is valid on both pos/neg edges of

raw data clock.

Otherwise, raw data is valid only on positive edge of raw data

clock.

•

1'b0: Double-data-rate disabled (default)

•

1'b1: Double-data-rate enabled

[3]

ENABLE_RAW_DATA_CLK

Enables raw data clock.

•

1'b0: Raw data clock disabled (default)

•

1'b1: Raw data clock enabled

[2]

ENABLE_SPDIF_CLK

Enables SPDIF encoding clock.

•

1'b0: SPDIF clock disabled (default)

•

1'b1: SPDIF clock enabled

[1:0]
