• WIDE AGC DYNAMIC RANGE:
GCR = 53 dB TYP
• ON-CHIP VIDEO AMPLIFIER:
VOUT = 1.25 VP-P at single-ended output
• SUPPLY VOLTAGE:

• PACKAGED IN 8 PIN SSOP SUITABLE FOR
SURFACE MOUNTING
DESCRIPTION
NEC's UPC3217GV and UPC3218GV are Silicon Monolithic
ICs designed for use as AGC amplifiers for digital CATV,
cable modems and IP telephony systems. These ICs consist
of a two stage gain control amplifier and a fixed video gain
amplifier. The devices provide a differential input and differ-
ential output for noise performance, which eliminates shield-
ing requirements.
The package is 8-pin SSOP (Shrink Small Outline Package)
suitable for surface mount.
These ICs are manufactured using NEC's 10 GHz fT
NESATΙΙ AL silicon bipolar process. This process uses
silicon nitride passivation film. This material can protect chip
surface from external pollution and prevent corrosion/migra-
tion. Thus, these ICs have excellent performance, uniformity
and reliability.
NEC's stringent quality assurance and test procedures en-
sure the highest reliability and performance.
