General description of UV1315:
The UV1315 tuner belongs to the UV 1300 familiy of tuners, which are designed to meet a wide range of applications.
It is a combined VHF, UHF tuner suitable for CCIR systems B/G, H, L, L, I and I. The low IF output impedance has been
designed for direct drive of a wide variety of SAW filters with sufficient suppression of triple transient.
Features of UV1315:
n Member of the UV1300 family small sized UHF/VHF tuners
n Systems CCIR:B/G, H, L, L, I and I; OIRT:D/K
n Voltage synthesized tuning (VST)
n Off-air channels, S-cable channels and Hyperband
n Standardized mechanical dimensions and pinning
n Compact size
