CXA1386P/K
8-bit 75MSPS Flash A/D Converter
Description
The CXA1386P/K are 8-bit high-speed flash A/D
converter ICs capable of digitizing analog signals at
the maximum rate of 75MSPS. The digital I/O levels
of these A/D converters are compatible with the
ECL 100K/10KH/10K.
The CXA1386P/K is pin-compatible with the
earlier models CXA1056P/K, CXA1016P/K,
respectively. They can be replaced by the
CXA1386P/K 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
• Differential linearity error: ±1/2LSB or less
• Integral linearity error: ±1/2LSB or less
• High-speed operation with maximum conversion
rate of 75MSPS (Min.)
• Wide analog input bandwidth: 150MHz (Min. for
full-scale input)
• Low Power consumption: 580mW (Typ.)
• Single power supply: –5.2V
• Low input capacitance: 17pF (Typ.)
• Built-in integral linearity conpensation circuit
• Low error rate
• Operable at 50% clock duty cycle
• Good temperature characteristics
• Capable of driving 50Ω loads

Description
Anlog GND.
Used as GND for input
buffers and latches of
comparators.
Isolated from DGND or
DGND 1/2.
Analog VEE
–5.2V (Typ.).
Internally connected
with DVEE
(resistance: 4 to 6Ω).
Ceramic chip
capacitors of at least
0.1µF should be used
to connect to AGND
and be placed near
the pins.
CLK input
Input complementary
to CLK.
With open connection,
kept at threshold
voltage (–1.3V).
Device is operable
without CLK input, but
use of complementary
inputs of CLK and CLK
is recommended to
obtain the stable high-
speed operation.
Digital GND (Used for
internal circuits and
output transistors)
