Description

      TC9142P is a C2-MOS LSI developed for controlling the motor of a quartz-lock D.D. recond player.Since an 8-bit D/A converter system has been employed for each of the speed control system (AFC) and the phase control system (APC),a wide reduction of external parts can made in comparison with coventional capacitor-type S/H systems,thus having realized adjustment free operation.Here you can get some information about the features.First,the speed-changeover positions are available at 33 1/3 and 45-rpm.Secondly,the crystal can be used up to 12 MHz,and crystal reference dividing frequency is selectable from three positions of 1/4,1/32 and 1/128 to increase the degree of freedom in the number of FG pulses of motor or crystal frequency,which allows a wide range of design to be made.Thirdly,the external oscillator makes possible fine adjustment of speed.The last one is that it is provided with strobe reference output and reverse signal output.
      The following is about the maximum ratings (Ta=25) of TC9142P .The supply voltage (VDD) is from -0.3 to 10.0 V.The input voltage (VIN) is from -0.3 to VDD+0.3 V.The power dissipation (PD) is 300 mW.The operating temperature (Topr) is from -30 to 75.The storage temperature (Tstg) is from -55 to 125.Then is about the electrical characteristics (VDD=7.5 V,Ta=25).The minimum operating supply voltage (VDD(1)) is 5.0 V and the maximum is 9.5 V at X'tal=6MHZ,CPIN=1.5MHz.The minimum operating supply voltage (VDD(2)) is 7.5 V and the maximum is 9.5 V at X'tal=12MHZ,CPIN=3.0MHz.The typical operating supply current (IDD) is 5.5 mA and the maximum is 12 mA at X'tal=12MHZ,CPIN=3.0MHz.The maximum FGIN operating frequency range (fFG) is 10kHz at VDD=5.0 to 9.5 V and VIN=0.5Vpp.The minimum FGIN threshold voltage range (VTH(FG)) is from 0.2*VDD to 0.8*VDD V at VDD=5.0 to 9.5 V at time of DC connection.The typical ladder resistor temperature factor is +0.55 %/deg. and the maximum is 0.8 %/deg.The minimum amplifier feedback resistor (Rf) is 100 k,the typical is 200 k and 500 k.
