description
The SN65LVDS1023 serializer and SN65LVDS1224 deserializer comprise a 10-bit serdes chipset designed to
transmit and receive serial data over LVDS differential backplanes, at equivalent parallel word rates from
30 MHz to 66 MHz. Including overhead, this translates into a serial data rate between 360 Mbps and 792 Mbps
payload encoded throughput.
Upon power up, the chipset link can be initialized via a synchronization mode with internally generated SYNC
patterns, or the deserializer can be allowed to synchronize to random data. By using the synchronization mode,
the deserializer establishes lock within specified, shorter time parameters.
The device can be entered into a power-down state when no data transfer is required. Alternatively, a mode is
available to place the output pins in the high-impedance state without losing PLL lock.
The SN65LVDS1023 and SN65LVDS1224 are characterized for operation over ambient air temperature of
–40°C to 85°C.
