C1,C2 ----------- These capacitors are for stabilization of Vcc and VREF.
VR1 ----------- It is decided considering a current capability of VREF. (The capability is about 5mA.)
Recommended value is around 10k
C3,D1 ----------- They are for a soft start function. A time constant is decided considering VR1.
Cagc1,2 ----------- These capacitors are for stabilization of AGC circuit. A larger capacitor improves a
stability of the system, however a system response is degraded.
Recommended capacitor value is around 1μF.
Cosc ---------- This capacitor is for the saw-wave generation.
Recommended capacitor value is around 1000pF.
R1,R2,R3,R4 ----- They are for the gain setting of the error Amp. R2 should be several k
to dozens of k
C4,C5 to set a voltage gain 20dB to 40dB at f = 1kHz, so that the feed back loop is stable.
When the voltage gain is too low, it causes jitter.
Recommended values of C4, C5 and R1 are ; C4 = dozens of pF to several hundreds pF,
C5 = several thousands pF to tens of thousands pF, R1 = dozens of k
to several
hundreds k
.
Ragc ----------- This resistor is for the AGC setting of DOUT. Recommended value is 27k
.
R5 ----------- It is a pull-up resister of DOUT output, because DOUT is configured by the open
collector circuit. Recommended value is several k
.
