ACD0900 VHF/UHF CATV/TV Tuner Downconverter Data Sheet - Rev 2.2 FEATURES • • • • • • • • Integrated Monolithic Downconverter 8 dB Noise Figure 10 dB Conversion Gain High Linearity Small Size Low Cost High Reliability RoHS-Compliant Package Option S3 Package Modified 16 Pin SOIC PRODUCT DESCRIPTION The ACD0900 MMIC is a high performance downconverter fabricated entirely in GaAs. It is designed for use as the second conversion stage in double-conversion tuners and cable modems, downconverting 900 -1200 MHz RF inputs to a fixed IF of 35 - 150 MHz (depending on LO frequency). IF1,+5V The IC incorporates a low noise amplifier, high linearity double balanced mixer, phase splitter and oscillator in a modified SOIC 16 lead surface mount package. The high degree of functionality allows tuner manufactures to reduce size and cost by lowering the component count and decreasing the amount of production alignment steps, while significantly improving performance and reliability. 1 16 IF2, + 5V 15 GND 14 OSCOUT MXR GND 2 N/C 3 PHASE 13 SPLITTER GND 4 GND 12 5 OSC RFIN 6 ISET 7 GND 8 11 TCKT 10 +5V 9 N/C LOW NOISE AMP.

RF Input Power - + 10 dB m LO Input Power - + 17 dB m Thermal Resistance - 25 °C/W Storage Temperature Stresses in excess of the absolute ratings may cause permanent damage. Functional operation is not implied under these conditions. Exposure to absolute ratings for extended periods of time may adversely affect reliability. Note: (1) VTCKT : Maximum voltage that may be applied to pin 11 of the device without damaging the IC. DC blocking capacitor (1500 pF) between pin 11 and the external tuning circuit is mandatory.
