analog ASIC & digital ASIC

is there anything like analog asic and digital asic????

if yes than whts the difference.............

An application-specific integrated circuit (ASIC) is an integrated circuit (IC) customized for a particular use, rather than intended for general-purpose use.
So I assume that you know the difference between analog IC and digital IC. It quiet same.
A digital ASIC is comprised with the digital section of the design and analog ASIC controls the analog section like signal conditioning. The ASIC design may comprise both also.
Like for example, A combination of the digital ASIC and the analog ASIC controls a semiconductor laser so as to pulse-width-modulate and amplitude-modulate the light emitted by the semiconductor laser that may be pulse-width-modulated and amplitude-modulated. The digital ASIC comprises a reference pulse generator having delay time control unit and a pulse width generator for generating a plurality of different pulse widths using pulses having a plurality of phases generated by the reference pulse generator. The analog ASIC comprises control/modulation unit for controlling the semiconductor laser so as to pulse-width-modulate and amplitude-modulate the light emitted by the semiconductor laser using the plurality of different pulse widths generated by the pulse width generator. The reference pulse generator comprises an oscillator comprising combined multiple delay-time control unit, and control unit for controlling the oscillator so as to make the frequency supplied by the oscillator identical to the clock of the pixel data.
