CY7C9335A SMPTE-259M Decoder
BYPASS
DVB_EN
Bypass SMPTE decoding. BYPASS is ignored if DVB_EN is active (LOW). If BYPASS is HIGH at the
rising edge of CKR (and DVB_EN is HIGH), the data latched into the input register is routed around both
the NRZI decoder and the SMPTE descrambler and presented to the output register. If BYPASS is LOW
at the rising edge of the CKR clock (and DVB_EN is HIGH), the data present in the input register is routed
through the NRZI decoder and SMPTE scrambler.
Reframe. This output is the inverted DVB-EN signal.
CY7B9334 Port Select. When in DVB-ASI mode, this output will alternately select either the INA± or
INB± receiver port based on errors detected in the data stream. This allows CY7C9335A to operate with
normal and inverted DVB-ASI data streams (as would be commonly found on DVB-ASI streams routed
through SMPTE switches). This requires the CY7B9334 INA± and INB± inputs to be connected to the
same signal, but with INB± connected to invert the signal.
Horizontal Sync. This output toggles once every time that the TRS field is recognized. It changes state
one clock cycle prior to the first character of the TRS field (3FF in 10-bit hex) appearing at the PD
outputs. This output also toggles to indicate detection of a TRS sequence, even when the TRS characters
are at a different offset from the present offset and SYNC_EN is active (HIGH). This toggling action is
disabled when DVB_EN is active (LOW).
