Output
PARALLEL DATA BUS
Please refer to the Output Logic parameters in the DC Electrical
Characteristics table for logic level threshold and compatibility.
20-bit mode
20bit/10bit = HIGH
SMPTE mode (SMPTE_BYPASS = HIGH
and DVB_ASI = LOW):
Chroma data output for SD and HD
data rates.
DVB-ASI mode (SMPTE_BYPASS = LOW
and DVB_ASI = HIGH):
Not defined
Data-Through mode (SMPTE_BYPASS =
LOW and DVB_ASI = LOW):
Data output
10-bit mode
20bit/10bit = LOW
Forced LOW
G3RC_BYP
Input
CONTROL SIGNAL INPUT
Please refer to the Input Logic parameters in the DC Electrical
Characteristics table for logic level threshold and compatibility.
When this pin is LOW, the serial digital output is the buffered
version of the input serial data. When this pin is HIGH, the serial
digital output is the reclocked version of the input serial data.
G7
SMPTE_BYPASS
Input/Output
CONTROL SIGNAL INPUT/OUTPUT
Please refer to the Input/Output Logic parameters in the DC
Electrical Characteristics table for logic level threshold and
compatibility.
Indicates the presence of valid SMPTE data.
When the AUTO/MAN bit in the host interface register is HIGH
(Default), this pin is an OUTPUT. SMPTE_BYPASS is HIGH when the
device locks to a SMPTE compliant input. SMPTE_BYPASS is LOW
under all other conditions.
When the AUTO/MAN bit in the host interface register is LOW, this
pin is an INPUT:
No SMPTE scrambling takes place, and none of the I/O processing
features of the device are available when SMPTE_BYPASS is set
LOW.
When SMPTE_BYPASS is set HIGH, the device carries out SMPTE
scrambling and I/O processing.
When SMPTE_BYPASS and DVB_ASI are both set LOW, the device
operates in Data-Through mode.
