The DIODES PI7C9X3G816GP is a PCIe® GEN3 packet switch that supports 16 lanes of GEN3 SERDES in flexible 2-port, 3-port, 4-port, 5-port and 8-port configurations. The architecture of the PCIe packet switch allows the flexible port configuration by allocating variable lane widths for each port. The packet switch can be configured to have different port types such as upstream port, downstream ports and Cross-Domain End-Point (CDEP) ports to support various applications, which include port fan-out, dual-host connectivity. Inside the packet switch, multiple DMA channels are embedded to facilitate data communication more efficiently among host(s) and end-points.

The PI7C9X752 (752), is a 1.62V to 3.6V dual Universal Asynchronous Receiver and Transmitter (UART) with 5V tolerant serial(modem) inputs. The highly integrated device is designed for high bandwidth requirement in communication systems.Each UART has its own 16C550 compatible set of configuration registers, TX and RX FIFOs of 64 bytes, fully programmable transmitand receive FIFO trigger levels, TX and RX FIFO level counters, automatic RTS/CTS hardware flow control with programmablehysteresis, automatic software (Xon/Xoff) flow control, RS-485 half-duplex direction control, Intel or Motorola bus interface andsleep mode for power saving.

16C550 Quad UART Bridge Controller

The PI7C9X760 is a I2C-bus/SPI to a single-channel high performance UART bridge controller. It offers data rates up to 33Mbps and guarantees low operating and sleeping current. The PI7C9X760 also has up to 8 additional programmable general purpose I/O [GPIO] pins. The device comes in very small package, which makes it ideally suitable for cost efficient, handheld, battery operated applications. These UART bridges provide protocol conversion from I2C -bus or SPI to RS-232/RS-485/RS-422 and are fully bidirectional.
