UV1316, UV1336
General description of
UV1316:
The UV1316 tuner belongs to the UV 1300 family 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 UV1316:
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 Digitally controlled (PLL) tuning via IýC-bus
n Off-air channels, S-cable channels and Hyperband
n World standardized mechanical dimensions and world standard pinning
n Compact size
n Complies to “CENELEC EN55020” and “EN55013”
