... All Band TV Tuner IC (VHF-CATV-UHF) Description The CXA3025N is a single chip TV tuner IC which performs as a mixer, oscillator for UHF and VHF- CATV bands amplifier is also provided. This IC adopts a 24-pin SSOP package (0.8mm pitch) in response to the trend towards miniaturizing the tuner and automatic IC mounting. ...

... Care should be taken for grounding, etc. when placing external parts as high operating frequencies are present. In addition, since the GND pins (Pins and 19) also serve as heat dissipation pins, care should be taken to prevent heat problems. Care should also be taken to prevent electrostatic damage to high frequency I/O pins. – 7 – CXA3025N ...
