OSA pairs handle high-speed video transmission

The SX51 TOSA device transmits three video and one high-speed clock digital data lane at up to 3.5Gbit/s.

Omron Electronic Components Europe has released bi-directional optical subassembly (OSA) pairs that suit HDMI 1.3 high-definition (HD) video transmissions at speeds of up to 3.5Gbit/s.

Omron has also released an enhanced version of its existing SX4 DVI TOSA/ROSA pair.

The Omron P1TX/RX6A-SX51 TOSA/ROSA is a solution that offers video system designers an alternative to copper-based transmission lines, addressing the long-distance data transfer challenges of the bandwidth-intensive, high-speed data applications associated with HDMI 1.3 compliant HD video and audio formats.

The SX51 TOSA device transmits three video and one high-speed clock digital data lane at up to 3.5Gbit/s and the SX51 ROSA receives these signals and transmits and receives one low-speed signal, all on one multimode fibre.

This configuration enables the ROSA to output a control signal, which greatly increases the flexibility of system design, especially in HDMIT 1.3 applications, where manufacturers can implement their own system-specific features.

SX51 supports HDMI 1.3 requirements and specifications, enabling advanced deep-colour support, which uses up to 16 bits per pixel, effectively providing a dynamic colour spectrum of billions of shades, as well as true lossless audio playback through Dolby TrueHD and DTS-HD audio formats.

The SX4B is an enhanced version of its SX4A product, offering lower power consumption and a higher data rate.

The P1TX4B-SX4-01 TOSA will accept PECL, CML and LVDS inputs while the P1RX4B-SX4-01 ROSA outputs are compatible with CML.

An improved driver allows the transmitter to exhibit a 60% lower power consumption than the SX4A and the SX4B-D version can handle a data rate of 3.5Gbit/s per channel.

The SX4B also features a new angled optics block for improved mechanical mounting.

Omron is supporting the SX51 and the SX4 with design tools including a microcontroller reference circuit, reference circuits for the TOSA input and ROSA output, a reference circuit for the low-speed VCSEL (SX51), a reference circuit for the low-speed photo detector (SX51) and laser driver code .hex and .ee files.
