4.1.1 Serial Interface Connector (J1)
Evaluate this EVM by preparing a signal pattern generator like an FPGA, CPLD, MCU or some equipment
like the DG2020 for the input signals. J1 connects the signals BLANK (pin 7), SIN (pin 10), SCLK (pin 9),
LAT (pin 8), and GND (pin 6).
4.1.2 Serial Connector (J2)
Evaluation of the series connection of several TLC59282 is possible with this EVM. Connect J1 of the
second EVM with the serial connector, J2, of the first EVM. The signals BLANK (pin 7), SCLK (pin 9), LAT
(pin 8), and GND (pin 6) of the first EVM are directly connected to the second EVM. The output signal
SOUT (pin 10) of the first EVM is connected to the input signal SIN of the second EVM.
4.1.3 LED Connector (J3)
J3 can connect to the WLEDEVM-132 (not included), or single LEDs, or LED strings between V
LED
and
OUTx. WLEDEVM-132 contains 16 white LEDs connected with the anode to V
LED
and the cathode to
OUTx of TLC59282. J3 can also be connected to single LEDs or LED strings between V
LED
and OUTx.
The lower pins of J3 are connected to V
LED
, the upper pins of J3 are connected to the OUTx pins of the
TLC59282.
4.1.4 GND Connector (J4)
J4 connects to GND making the reference voltage available for measurement purposes.
4.1.5 V
LED
Connector (J5)
J5 supplies the LEDs (not included) with the anode voltage. Connect V
LED
between the positive node (pins
1 and 2, closer to J3) and the GND node (pins 3 and 4).
4.1.6 V
CC
Connector (J6)
J6 supplies the TLC59282 with the supply voltage. Connect V
CC
between the positive node (pins 1 and 2,
closer to J2) and the GND node (pins 3 and 4).
