L64733/L64734 Tuner and Satellite Receiver Chipset
Channel Data Output Interface
The Channel Data Output interface is the output path from the L64734.
It is typically connected to the input of the transport demultiplexer in a
set-top decoder application.
BCLKOUT
Byte Clock Out
This signal indicates valid data bytes on the CO[7:0] bus
when the L64734 is in Parallel Channel Output mode.
This signal cycles once every valid output data byte. It is
used by the transport demultiplexer to latch output data
from the L64734 at the BCLKOUT rate. Disregard the
BCLKOUT signal when the L64734 is in Serial Channel
Output mode.
Output
CO[7:0]
Channel Data Out
The CO[7:0] signals form the decoded output data port.
When the OF bit is 1 (Group 4, APR17), the L64734
operates in the Parallel Channel Output mode. In this
mode, the L64734 outputs the channel data as eight-bit-
wide parallel data on the CO[7:0] signals. In Serial
Channel Output mode (OF = 0), the L64734 outputs the
channel data as serial data on CO[0]. The data is latched
on every bit clock cycle. The chronological ordering in
Serial Channel output mode is: MSB oldest, LSB newest.
Output
COEn
Channel Output Enable
When asserted, the COEn signal enables the
ERROROUTn, CO[7:0], DVALIDOUT, BCLKOUT, and
FSTARTOUT signals. Operation of the receiver continues
regardless of the state of the COEn signal.
Input
DVALIDOUT
Valid Data Out
The DVALIDOUT signal indicates that the CO[7:0] signals
contain the corrected channel data. New data is valid on
the CO[7:0] signals when the DVALIDOUT signal is
asserted. DVALIDOUT is not asserted during the
propagated check and GAP bytes. The DVALIDOUT
signal is deasserted after the FEC_RST register bit
(Group 4, APR 55) is set to 1.
Output
ERROROUTn Error Detection Flag
The L64734 asserts the ERROROUTn signal at the
beginning of any frame that contains an uncorrectable
error; it deasserts ERROROUTn at the end of the frame
