        e                       DIGITAL ECHO(DIGITAL DELAY)                                              KARAOKE




DESCRIPTION
◊ The M65850P/FP is a CMOS IC for generating echo to be added to the voice through a
  "karaoke" microphone.
◊ It is optimal to provide the echo effect function for karaoke player, such as radio cassette
  recorders, mini audio components and television sets.
◊ Increased master clock frequency assures high-performance short delay,enabling the IC
  to be used for dolby prologic surround system.
                                                                                        PACKAGE
 FEATURES
• Built-in input/output filters, A-D and D-A converters,and memory
  realize a delay system with only a single chip.
• Built-in current control type clock oscillator circuit avoids clock
  affection outside,thus allowing prevention of undesired radiation.
• Delay time = 164 ms (with master clock set at 1MHz)
  (Selection of delay time in a range between 15ms and 200ms)                          Outline 1 4 P 4 ( P )
• Small package (14-pin DIP : 14P4,16-pin SOP:16P2N)                                   2.54mm pitch 300mil DIP
• Built-in 20Kbit SRAM
• Built-in auto reset circuit (The IC reset as power is turned on)
• Single power supply (5V)

     FUNCTION DESCRIPTION
 (1) Delay time Td
      The delay time can be calculated by the equation :

            Td=8N / fck ( N=the number of memory bits=20480 )

       When fck=1MHz ( fs=125kHz), Td can be set at 164ms.

       « Reference »
       The M65850P/FP adopts ADM ( Adaptive Delta Modulation ) system in A-D,D-A
       converters.
       The sampling frequency can be calculated by the following equation :
              fs=clock frequency / 8 ( Hz )
       For clock frequency ( fck )=1MHz, the calculated sampling frequency is :
              fs=1MHz / 8 =125kHz

(2) Clock oscillator circuit

    The M65850P incorporates a current control type clock                          Vcc
oscillator circuit in it, thus providing circuit configuration just by
connecting a resistor for current control to pin 13 ( FP:pin 14 )
CLOCK.
Fully internal clock supply prevents occurrence of undesired
radiation without affecting any external circuit.
                                                                         Rc                     Clock
                                                                                        *       oscillator
       The oscillator frequency is:                                                  13
                                                                              *   (FP:14)       circuit
                  fck = 1 MHz. ( Rc=120kΩ )

  The resistor for current control can be calculated using the
                                                                                            Clock

       (4) Mute
            When power is turned on, the mute function works automatically to
            prevent noise generation. (Here, however, "mute" means the
            function which prevents noise generation after the reset time.)
