µ
PC1663
DC to VHF WIDEBAND DIFFERENTIAL INPUT AND OUTPUT AMPLIFIER IC
DESCRIPTION
The
µ
PC1663 is a differential input, differential output wideband amplifier IC that uses an high frequency silicon
bipolar process. This process improves bandwidth phase characteristics, input noise voltage characteristics, and low
power consumption when compared to conventional HF-band differential amplifier ICs.
These features make this device suitable as a wideband amplifier in high-definition TVs, high-resolution monitors,
broadcasting satellite receivers, and video cameras, as a sense amplifier in high-density CCD and optical pick-up
products, or as a pulse amplifier for optical data links.
TM
These ICs are manufactured using NEC’s 6 GHz f
T
NESAT I silicon bipolar process. This process uses silicon
nitride passivation film and gold electrodes. These materials can protect chip surface from external pollution and
prevent corrosion/migration. Thus, these ICs have excellent performance, uniformity and reliability.

NOTES ON CORRECT USE
(1)
(2)
(3)
(4)
(5)
Observe precautions for handling because of electro-static sensitive devices.
Form a ground pattern as wide as possible to minimize ground impedance (to prevent undesired
oscillation).
The bypass capacitor should be attached to V
CC
line.
When gain between Gain 1 and Gain 2 is necessary, insert adjustment resistor (0 to 10 kΩ) between
Ω
G
1A
and G
1B
to determine gain value.
Due to high-frequency characteristics, the physical circuit layout is very critical. Supply voltage line
bypass, double-sided printed-circuit board, and wide-area ground line layout are necessary for stable
operation. Two signal resistors connected to both inputs and two load resistors connected to both
outputs should be balanced for stable operation.
