Pin Name Pin No I/O Description
HSDI1_AMCLK_IN 169 I Audio Master Clock Input. This clock is used to decode the bi-
phase encoding of 60958 data.
This pin is also used to input the 1.5*BCK for Flow Control
mode.
MLPCM Interface, HSDI1 Audio Port, and HSDI1 video port
share buffer 1. Only one interface can access the buffer at a
time.
HSDI1_AMCLK_OUT 170 O Audio Master Clock Output. This clock is derived from the
VCO_CLK input. 60958 data output from iceLynx-Micro is bi-
phase encoded using this clock.
HSDI1_AUDIO_ERR 171 O Audio Error Signal. iceLynx-Micro asserts this signal
whenever an Audio Error condition occurs. (Receive from
1394 only.)
HSDI1_AUDIO_MUTE 172 O Audio Mute Status. iceLynx-Micro asserts this signal
whenever an Audio Mute condition has occurred, and
hardware has muted the HSDI1 audio interface. (Receive
from 1394 only.)
HSDI1_AV 155 O HSDI Port 1 Available. Programmable. Default active low.
For receive from 1394, this signal indicates if a 1394 packet is
available in the receive buffer for reading. The HSDI_AV
signal for MPEG2 data also depends on time stamp based
release.
For transmit onto 1394, this signal can be used to indicate
buffer level in HSDI TX mode 8 and 9 by programming a CFR.
This pin can be used to indicate buffer level in transmit mode
by programming a CFR. If the buffer level is above a
programmed level, HSDI_AV is asserted.
HSDI1_CLK 153 I/O HSDI Port 1 Clock. Programmable. Default rising edge
sample. This clock is used to operate the HSDI port 1 logic.
In parallel mode, the maximum clock is 27MHz. In serial
mode, the maximum clock is 70MHz.
This signal can be used as HSDI1_SACD_MCLK for SACD
Transmit and Receive.
MLPCM Interface, HSDI1 Audio Port, and HSDI1 video port
share buffer 1. Only one interface can access the buffer at a
time.
HSDI1_D0 158 I/O HSDI Port 1 Data 0 Pin. Data 0 is the least significant bit on
the HSDI data bus. In serial mode, only HSDI0_D0 is used.
This signal can be used as HSDI1_SACD_D0 for SACD
Transmit and Receive.
