4. POWER SUPPLIES
The CS5376A has three sets of power supply in-
puts. Two sets supply power to the I/O pins of the
device (VDD1, VDD2), and the third supplies
power to the logic core (VD). The I/O pin power
supplies determine the maximum input and output
voltages when interfacing to peripherals, and the
logic core power supply largely determines the
power consumption of the CS5376A.
4.1 Pin Descriptions
VDD1, GND1 - Pins 54,53
Sets the interface voltage to a microcontroller and
system telemetry. Can be driven with voltages from
3.3 V to 5 V.
VDD1 powers pins 1-5 and 41-64:
TRST, TMS, TCK, TDI, TDO
GPIO6 - GPIO11:EECS
SSO, SCK1, SSI, MISO, MOSI, SINT,
RESET, BOOT, TIMEB, CLK, SYNC
SDDAT, SDRDY, SDCLK, SDTKO, SDTKI
VDD2, GND2 - Pins 11, 25, 24, 38
Sets the interface voltage to the modulators, test
DAC, and serial peripherals. Can be driven with
voltages from 3.3 V to 5 V.
VDD2 powers pins 8-37:
TBSCLK, TBSDATA
MCLK/2, MCLK, MSYNC
MDATA1 - MDATA4
