Additional Information

Bipolar Analog SMT ICs

The uPC2798GR is a Silicon monolithic IC designed for use as QAM IF down converter for digital CATV. This IC consists of AGC amplifier, mixer, oscillator, and video amplifier.

Features:
- Low distortion AGC amplifier - IIP3 = -9dBm
- On chip IF convertor - fin = 30 to 250MHz
- On chip video amplifier - VOUT = 3.0VP-P (differential, @ RL = 1k
- Supply voltage: 5 V

Recommended Operating Range
Supply Voltage 1: 4.5V to 5.5V
Supply Voltage 2: 4.5V to 10.0V
Operating Ambient Temperature 1 (VCC1=VCC2=4.5V to 5.5V): -40 to 85C
Operating Ambient Temperature 1 (VCC1=4.5V to 5.5V, VCC2=4.5V to 10.0V): -40 to 75C

Electrical Characteristics (TA=25C):

TOTAL BLOCK (RL = 1kΩ, by measurement circuit 5)
Circuit Current 1 (no input signal, Vcc1 = Vcc2 = 5 V): 35.5mA typ.
Maximum Conversion Gain 1 (VAGC = 4.0 V, G1A-G1B pins: short): 74dB typ.
Maximum Conversion Gain 2 (VAGC = 4.0 V, G1A-G1B pins: open): 58dB typ.
Circuit Current 2 (no input signal, Vcc1 = 5 V, Vcc2 = 9 V): 47mA typ.
Minimum Conversion Gain 3 (VAGC = 1.0 V, G1A-G1B pins: short): 43.5dB typ.
Minimum Conversion Gain 4 (VAGC = 1.0 V, G1A-G1B pins: open): 22.5dB typ.

AGC AMPLIFIER + MIXER BLOCK (@Vcc1 = 5 V, RL = 50Ω, by measurement circuit 1)
Circuit Current 3 (no input signal): 23.0mA typ.
RF Input Frequency Range: 30 - 250MHz
IF Output Frequency Range: DC - 150MHz
AGC Dynamic Range (VAGC = 1.0 to 4.0 V): 32dB typ.
AGC Voltage High Level (@ Maximum Gain): 4.0V min.
AGC Voltage Low Level (@ Minimum Gain): 1.0V max.
