LM2512SMs are dual, low-voltage-differential signaling (LVDS) serdes designed for applications where noise, jitter, and switch times have to be kept to a minimum. The LM2512SM/NOPB is a non-operational version of the device which can be used to evaluate the device\'s performance, as well as its various features.

The LM2512SM/NOPB is a single-chip serializer/deserializer (SerDes) designed to provide clock and data recovery, differential signal multiplexing, and LVDS compliant outputs. It is designed for applications such as Gigabit Ethernet, FibreChannel, and Infiniband. The device supports data rates up to 5.25 Gbps and can be configured for full-duplex or half-duplex operation.

The device is powered by a 3.3V power supply and has an operating temperature range of -40°C to +85°C. It is also RoHS compliant and can be operated in a range of environmental conditions. The pinout and package option are also adaptable to a variety of applications.

The working principle of the LM2512SM/NOPB is based on a differential signal multiplexing technique. The serial input is demultiplexed into two separate differential output channels, each of which is then encoded into a separate LVDS data stream. The differential output data is transmitted over a pair of LVDS-compliant lines, with the output from each line being inverted from the input. The output from each line is then deserialized and sent in parallel format back to the input for serialization.

The device also features an integrated phase-locked loop (PLL) for clock and data recovery. The PLL uses a combination of a voltage-controlled oscillator (VCO) and a phase detector to lock the clock portion of the data stream, while a digital phase-locked loop (DPLL) is used to lock the data portion. This ensures the data is recovered accurately while allowing the clock to track the data. The device also features a jitter attenuator circuit which can reduce jitter on the output. And lastly, the device has programmable control registers, allowing the user to configure the various parameters of the device, such as the data rate, phase adjustment, and output drive strength.

The LM2512SM/NOPB is a multi-functional, low-voltage-differential signaling (LVDS) SerDes designed for a wide variety of applications that require high-speed, low-power, and low-jitter signals. The device features a differential signal multiplexing technique for serialization and deserialization, an integrated phase-locked loop for clock and data recovery, and a jitter attenuator circuit for reduced jitter on the output. The device is also configurable through programmable control registers, allowing the user to customize the device\'s parameters for their application.

The LM2512SM/NOPB is a versatile, low-power device that enables reliable operation in a variety of applications, such as Gigabit Ethernet, FibreChannel, and Infiniband. The device\'s small size, low-voltage operation, and reliable performance make it an ideal solution for demanding applications that require high-speed, low-power, and low-jitter signals.
