Circuit Operation
The LC78858V consists of three main blocks: the digital filter block, the sigma-delta D/A converter block, and the
analog filter block.
[Digital Filter Block]
The LC78858V performs the following calculations.
[Sigma-Delta D/A Converter Block]
This circuit accepts 8fs data input and outputs 256 fs or 384 fs 1-bit data sequence.
[Analog Low-Pass Filter Block]
This block consists of an analog low-pass filter that consists of on-chip resistors, capacitors, and operational amplifiers.
This block converts the 256 fs or 384 fs 1-bit data streams A and B directly to an analog voltage output.
