GS9060 Data Sheet
When H_CONFIG is set HIGH, TRS based blanking is enabled. In this case, the H
output will be HIGH for the entire horizontal blanking period as indicated by the H
bit in the received TRS ID words.
The timing of these signals is shown in Figure 3-3.

3.8 DVB-ASI Functionality
The GS9060 conforms to DVB-ASI standard EN 50083-9:1998.
The GS9060 is said to be in DVB-ASI mode once the device has detected 32
consecutive DVB-ASI words without a single word or disparity error being
generated. The device will remain in DVB-ASI mode until 32 consecutive DVB-ASI
word or disparity errors are detected, or until SMPTE TRS ID words have been
detected.
The lock detect block may also drop out of DVB-ASI mode under the following
conditions:
•
•
•
•
RESET_TRST is asserted LOW
CDx is HIGH
SMPTE_BYPASS is asserted HIGH
DVB_ASI is asserted LOW
K28.5 sync patterns in the received DVB-ASI data stream will be detected by the
device in either inverted or non-inverted form.
The application layer must set SMPTE_BYPASS LOW and DVB_ASI HIGH in
order to enable DVB-ASI operation.
