Chau Light ZSRGB-2017H-08-Z3

The ZSRGB-2017H-08-Z3 features high efficiency, high power consumption, wide viewing angle, and a compact package form factor, making it an ideal LED for all lighting applications. The chip uses single-wire communication, transmitting signals via a return-to-zero encoding scheme. After power-on reset, the chip receives data from the DIN pin; once 24 bits have been received, the DOUT port begins forwarding data to provide input to the next chip. Prior to forwarding, DOUT remains pulled low. At this point, the chip will not accept new data. The three PWM output pins — OUTR, OUTG, and OUTB — generate signals with corresponding duty cycles based on the received 24-bit data, at a signal frequency of 4 kHz. If a RESET signal is applied to the DIN pin, the chip sends the received data to the display output. After the RESET signal ends, the chip resumes receiving new data; once the first 24 bits are received, data is forwarded via DOUT. Before receiving a RESET code, the outputs on OUTR, OUTG, and OUTB remain unchanged. Upon receiving a low-level RESET code of 80μs or longer, the chip outputs the 24-bit PWM pulse-width data just received to the OUTR, OUTG, and OUTB pins. The chip employs automatic reshaping and forwarding technology, so the number of cascadable chips is not limited by signal transmission constraints — only by refresh rate requirements. For example, in a 1024-stage cascade design, the refresh time is 1024 × 0.4 × 2 = 0.8192 ms (chip data propagation delay is 0.4μs), with no flickering whatsoever.
