2.3.2 60-Pin HD Connector
The 60-pin HD connector provides the high speed LVDS data, control signals (SPI, UART, I
2
C, NRST,
NERR, SOPs) and JTAG debug signals. The connector can be connected to the MMWAVE-DEVPACK
board to further get to the standard TSW1400 EVM.
Figure 6 shows the HD connector, and Table 3
provides the connector information.
Figure 6. HD Connector
(1)
Indicates the state of the onboard VIO supply for the AWR device coming from the onboard PMIC. A HIGH on the PGOOD
signal (3.3 V) indicates the supply is stable. Because the I/Os are not failsafe, the MCU must not drive any I/O signals to the
AWR device before this I/O supply is stable to avoid leakage current into the I/Os.
