Linear ReDrivers deliver enhanced signal integrity performance
14-05-2021 | Diodes Inc | Power
Diodes Incorporated has boosted its position in the linear ReDriver IC market by launching the 1.8V PI2DPX1066, PI2DPX1217, and PI2DPX1263. Ideal for multiple applications, including notebook and desktop PCs, smartphones, docking stations, gaming consoles, tablets, monitors, and virtual reality equipment. These parts utilise a lower level supply voltage and use less power than competing products. They meet the expanding demand within the consumer electronics, computing, and communications sectors for USB Type-C and DisplayPort 2.0 (DP2.0) ReDrivers.
The PI2DPX1066 and PI2DPX1217 are power-efficient, 1.8V-rated 4-to-4 channel configuration ICs for USB Type-C implementation and support data rates of 10Gbps per channel. Both devices feature four different modes – specifically, SuperSpeed USB 10Gbps, SuperSpeed USB 20Gbps, SuperSpeed USB 10Gbps/2-lane DP1.4/DP2.0 (UHBR10), and 4-lane DP1.4/DP2.0 (UHBR10).
Configuration of the new USB Type-C ICs is done through their respective I2C interfaces. This results in the option to select between 16 different equaliser settings and four different flat gain settings. These protocol-agnostic devices are transparent to channel link training and display latencies below 300ps and deliver industry-leading signal integrity parameters within the domain of linear ReDrivers. The PI2DPX1066 powers up in a high-impedance safe state for notebook PC applications, while the PI2DPX1217 reverts to a default USB bypass state when powering up, as required in smartphone applications.
The devices provide engineers with a compelling mix of lower power operation, compact size (with no heavy pin count), and significant application flexibility (due to their signal integrity adjustment capabilities). All three ICs support an industrial temperature range comprising -40C to +85C. They all support power-saving operation when idle, unplugged, or disabled states apply.
The ICs are provided in a low-profile 32-pin TQFN package with 2.85mm x 4.5mm x 0.35mm dimensions.
