The LDC3114 is a 4-channel inductance-to-digital converter for low-power proximity and touch button sensing

The LMK1D1208I is an I2C programmable LVDS clock AD5293BRUZ-100 buffer. The device features two inputs and eight pairs of differential LVDS clock outputs (OUT0 to OUT7) with minimal clock distribution skew. Inputs can be LVDS, LVPECL, LVCMOS, HCSL or CML.

The LMK1D1208I is designed for driving 50Ω transmission lines. When driving the input in single-ended mode, apply an appropriate bias voltage to the unused negative input pin.

I2C programming enables the device to be configured as a single bank buffer (one of two inputs assigned to eight output pairs) or dual bank buffers (each input assigned to four output pairs). Each output can be configured to have standard (350 mV) or enhanced (500 mV) swing. The device also integrates individual output channel enable/disable via I2C programming. The LMK1D1208I has fail-safe inputs that prevent the output from oscillating in the absence of an input signal and allow an input signal before VDD is supplied.

The device operates in a 1.8-V, 2.5-V, or 3.3-V power supply environment and is characterized from –40°C to 105°C (ambient temperature).
