General Description


The LM4308 device adapts a 18-bit CPU style display interfaces to a MPL-2 SLVS differential serial link for displays. Two chip selects support a main and sub display up to and beyond 640 x 480 pixels. A mode pin configures the device as a Master (MST) or Slave (SLV). Both WRITE and READ operations are supported. CPU interface widths below 18-bits are supported by tieing unused inputs to a static level.

The differential line drivers and receivers conform to the JEDEC SLVS Standard. When noise is picked up as common-mode, it is rejected by the receivers. This is further enhanced with the 50 Ohm output impedance of the drivers. The 100 Ohm termination is integrated into the receivers.

Data integrity is insured with a 5-bit CRC field. CRC checking is done for both WRITE and READ operations. An Error (ERR) pin reports the occurrence of an error. A Write Only mode is also provided.

The interconnect is reduced from 23 signals to only 4 active signals with the LM4308 chipset easing flex interconnect design, size constraints and cost.

A low power sleep state entered when the PD* inputs are driven low.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
