M52957FP
DISTANCE DETECTION SIGNAL PROCESSING FOR 3V SUPPLY VOLTAGE
DESCRIPTION
M52957FP is a semiconductor integrated circuit containing
distance detection signal processing circuit for 3V supply voltage.
This device transforms each optical inflow current I1 and I2 from
PSD SENSOR into the voltage, and integrates that output after
doing calculation corresponds to I1/(I1+I2), and outputs it as the
time data(pulse term).
FEATURES
• Wide supply voltage range Vcc=2.2 to 5.5V
• Includes clamp level switching circuit
(Switch is 16 kinds by outside control)
• Includes standby function
• Includes power on RESET function
APPLICATION
Auto focus control for the CAMERA
Sensor for short distance etc
RECOMMENDED OPERATING CONDITION
Supply voltage range......................................................2.2 to 5.5V
Rated supply voltage.................................................................3.0V

CONTROLS
(1) STB
This terminal enables IC to operate. IC is Standby at HIGH in
this terminal. IC can operate at LOW in this terminal.
(2) RESET
This terminal resets the whole IC including a logic. This terminal
resets IC at HIGH. This terminal cancel resetting IC at the edge
from HIGH to LOW. IC includes power on reset function. The
control from external is also possible. The reset term in IC
takes OR between power on reset and control signal from
external.

While this terminal is HIGH,dielectric divide pole
countermeasures circuit of integration condenser is active.
(3) CLALV
This terminal sets up clamp level.
As including D/A of 4bit,16way clamp level setting is possible by
inputting clock after reset is canceled(include none clamp).
Set up current value of each bit is on the right table.
The number of input clock and set up clamp level is as follows.

Clamp level is established with fall edge of input clock.
It repeats the same value after 16 clock.
