Digital isolators support up to 150 Mbps

5 August 2009 Analogue, Mixed Signal, LSI

The new Si84xx ISOpro digital isolator family from Silicon Laboratories supports as many as six unidirectional isolation channels capable of data rates up to 150 Mbps. Offering space-efficient packaging options, a choice of isolation ratings up to 2,5 kVRMS and highly integrated I²C isolators, the ISOpro family delivers system design flexibility for use in applications such as power supplies, motor control systems, hybrid electric vehicles, industrial networking, medical and consumer products.

The devices boast jitter performance of less than 250 ps to ensure robust and reliable data transmission over the -40°C to +125°C temperature range. Electrostatic discharge (ESD) performance is to 4 kV human body model (HBM), 2 kV charged device model (CDM) and 400 V machine model (MM) to enable reliability in harsh application environments. Over 25 kV/μs of common mode transient immunity (CMTI) and up to 50 V/m of electric field immunity provide safe operation in applications such as switch mode power supplies, motor control and industrial networking.

For systems with bidirectional communications ports, such as Power over Ethernet (PoE) power sourcing equipment (PSE), switch mode power supplies (SMPS) and isolated SMBus or PMBus interfaces, the ISOpro family includes single-chip, I²C-compatible isolators. The Si8400 provides bidirectional isolated channels on both the serial data and serial clock lines, combining the I²C transmit and receive lines to reduce BOM cost and complexity. The Si8405 offers two additional independent unidirectional channels for system signals such as a reset or interrupt. In addition, the Si8400 and Si8405 support bus speeds of up to 1,7 Mbps and I²C clock stretching to simplify the design task of matching bus speeds.

The devices feature typical power consumption of less than 1,7 mA at 10 Mbps and less than 4 mA at 100 Mbps, as well as an optional 200 μA sleep mode. The Si84xx also features typical propagation delays of less than 10 ns, enabling higher bandwidths in closed loop systems and higher data rates in communication links.
