Mindspeed Technologies M21165 asynchronous crosspoint switches available from Caelera

Supplier News

Mindspeed Technologies have announced the expansion of their crosspoint switch portfolio with the addition of M21165 160x160, 6.5 Gbps asynchronous crosspoint switch. The M21165 160x160, 6.5 Gbps asynchronous crosspoint switch, available from Caelera , can provide 25,600 switching paths on a single die.

This non-blocking crosspoint switch is protocol agnostic, with each independent channel operating at any data rate up to 6.5 Gbps. The device is suitable for a variety of applications such as broadcast video routing and switching, blade server, storage and dense wave division multiplexing (DWDM). Implemented in geometry complementary metal-oxide-semiconductors (CMOS), the M21165 160x160, 6.5 Gbps asynchronous crosspoint switch is a low power solution for large systems. Mindspeed Technologies observe that this low-power CMOS device offers high level of signal integrity and performance.

Each input features individually programmable input equalisation to compensate losses accumulated across the backplane. In addition, all outputs provide output de-emphasis, programmable on a per lane basis. These signal conditioning features are critical for maintaining signal integrity for high-speed designs system implementations.

The M21165 160x160 6.5 Gbps asynchronous crosspoint switch can be configured to switch each channel as individual lanes (lane mode) or in a group of four channels (group mode) with low intra-channel skew. The various options of the crosspoint switch and the switch state can be configured with registers accessed through both two-wire and four-wire serial interfaces, or through a parallel interface, offering flexibility.

The device requires a 1.2V core supply, while the input and output drivers may be powered by a 1.2V or 1.8V supply. When a 1.2V supply voltage is used, the M21165 asynchronous crosspoint switch typically consumes 22W. The M21165 asynchronous crosspoint switch features individual, per lane, loss of signal alarms, as well as integrated temperature sensors, easing failure diagnosis.
