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 differential output for noise performance, which eliminates shielding requirements. The package is 8-pin SSOP (Shrink Small Outline Package) suitable for surface mount.

UPC3218GV
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/migration. Thus, these ICs have excellent performance, uniformity and reliability. NEC's stringent quality assurance and test procedures ensure the highest reliability and performance.

Gain control pin. This pin's bias govern the AGC output level. Minimuim Gain at VAGC = 0.5 V Maximum Gain at VAGC = 4.5 V Recommended to use a 0 to 5 V AGC range for the system and divide this voltage through a resistive bridge (see evaluation board). This helps make the AGC slope less steep. Ground pin. This pin should be connected to system ground with minimum inductance. Ground pattern on the board should be formed as wide as possible. 2.2 Signal output pins of video amplifier
