Read/Write Amplifier (with Built-in Filters) for FDDs
32 pin QFP (Plastic)
CXA1720Q
• Supply voltage detection circuit prohibits error
writing during power ON/OFF or abnormal voltage.
• Power consumption is kept down to 115 mW (typ.)
and this IC is suitable for use with battery-driven
FDDs.
• Built in Time constant capacitors for monostable
multivibrator Nos. 1 and 2. (The pulse width for
monostable multivibrator No. 2 is fixed.)
• Power saving function reduces power consumption
when the IC is not in use. When in power saving
mode (5 mW typ.), only the power supply ON/OFF
detector functions.
• The Write driver has a built-in reset circuit. When
the mode is switched from Read mode to Write
mode, the Write current flows from head 0A if head
side 0 is selected and from head 1A if head side 1
is selected.
Description
The CXA1720Q is an IC for use with floppy disk
drives, and contains a Read circuit (with built-in
filters), Write circuit, Erase circuit, and supply
voltage detection circuit, all into a single chip.
Features
• Single 5 V power supply.
• Filter system can be switched among four modes:
1M/2M, and inner track/outer track. This allows for
a significant reduction in the number of external
parts such as differentiator constants, low-pass
filters, and switches. (Compared with conventional
Sony products, the number of parts has been
reduced by one-half.)
• Filter characteristics can be customized.
• Low pre-amplifier input conversion noise voltage of
2.0 nV/
√ Hz (typ.) keeps Read data output jitter to
a minimum. The pre-amplifier voltage gain can be
selected as either 100
× or 200×.
• The monostable multivibrator No. 1 pulse width
switching function for the time domain filter permits
switching between 1M and 2M mode.
• Write current switching function permits switching
of the Write current among four modes: 1M/2M
and inner track/outer track. (Filter inner track/outer
track switching is separate.)
