Exercise 1.1
Q:
How do I calculate the value of the series dropping resis-
tor R1, shown in Figure 3
A:
The values for R1, R
Q
, R
R
and R
VPO
can be determined
by using Equations 1 (A, B, C, and D).
Where:
V
PO
= Voltage between pins P0 and P- (U1 - U22
and U1 - U16).
I
QPO
= Quiescent current flowing into pin P0.
I
QPTO
= Quiescent current of the HBR-2521 fiber-
optic receiver.
I
VDR
= Current flowing through R3 and R4 (volt-
age divider reference).
I
RP
= Current flowing through pull up resistor R2
(in “ON” or “OFF” state)

= 30V DC
I
QPO
= 2.75mA at V
P0
= 15V
I
OPTO
= 5mA
I
VDR
= 2.5mA
I
RP(ON)
= 5mA, R2 = 1K, VR2 = 5V
Use V
P0
= 15V
3. Solve for R
