CXA1396D
8-bit 125 MSPS Flash A/D Converter
Description
The CXA1396D are 8-bit ultrahigh-speed flash A/D
converter ICs capable of digitizing analog signals at
the maximum rate of 125 MSPS. The digital I/O
levels of these A/D converters are compatible with
the ECL 100K/10KH/10K.
The CXA1396D is pin-compatible with the earlier
model CX20116. They can replace the earlier models
respectively, without any design changes, in most
cases. Compared with the earlier models, these new
models have been greatly improved in performance,
by incorporating advanced process, new circuit
design and carefully considered layout.
Features
Ultrahigh-speed operation with maximum
conversion rate of 125 MSPS (Min.)
Wide analog input bandwidth: 200MHz (Min. for
full-scale input)
Low power consumption: 870mW (Typ.)
Single power supply: –5.2V
Low input capacitance
Built-in integral linearity compensation circuit
Low error rate
Operable at 50% clock duty cycle
Good temperature charactcristics
Capable of driving 50loads
42 pin DIP (Ceramic)
Structure
Bipolar silicon monolithic IC
Applications
Digital oscilloscopes
HDTV (high-definition TVs)
Other apparatus requiring
conversion

Description
Analog GND.
Used as GND for input buffers
and latches of comparators.
Isolated from DGND1, DGND2.
Analog VEE.
–5.2V (Typ.).
Internally connected with DVEE
(resistance: 4 to 6).
A ceramic chip capacitor of at
least 0.1µF should be used to
connect to AGND and be
placed near the pins.
CLK input
Complementary input to CLK.
With open connection, kept at
threshold voltage (–1.3V).
Device is operable without CLK
input, but use of omplementary
inputs of CLK and CLK is
recommended to obtain the
stable high-speed operation.
Digital GND for internal
circuits.
Digital GND for output
transistors.
Digital VEE.
Internally connected with AVEE
(resistance: 4 to 6).
A ceramic chip capacitor of at
least 0.1µF should be used to
connect to DGND near the
pins.
