Description
The M3-2300LQL F/2F decoder integrated
circuit is designed for use in magnetic strip card
reader system.
The F/2F read/decoder IC will recover clock
and data signals from an F/2F data stream
generated from a magnetic head. M3-2300LQL
will function for data rates from 200 to 15,000
bits per second. Acquisition and tracking of the
data within this range is automatically.
M3-2300LQL is consisted by two major blocks
at each channel.
Amplify block-
This block amplifies and filters the signal read
from the magnetic reader head, rejects common
mode noise and detects signal peaks. It also
includes protection circuit to protect the
component.
And latches onto the data rate and performs the
recovery of individual bits from the F/2F data
stream.
Control block-
The enable and disable counters provide
initialization for the recovery block. These
counters initialize both bit recovery and the
signal conditioning and detection block.

M3-2300LQL application example (Vcc = 5.0V DC, tolerance ±5%)
Note1: Recommend RB2 use 10K~100K to increase circuit reliability and RB2 line should be short.
Note2. If your application must read Track2 with both bit density 75 BPI (ISO) and 210 BPI (non-ISO), you can adjust CP5 to 68P and CP6 to 4700P. The reader’s performance usually gets worse than the original one for only reading 75 BPI (ISO).
