10 / 27 page NXP Semiconductors TD1600ALF-4 Tuner module for digital terrestrial (OFDM) applications TD1600ALF-4 © NXP B.V. 2006. All rights reserved. Preliminary data sheet Rev.c — 23-04-2007 10 of 27 8.3 Overall performance from RF input to RF output Table 7. Overall performance from RF input to RF output Specification data refer to the overall performance from RF-input to RF-output. (valid for all tuners out of this family) Parameter Min Typ Max Unit Frequency range (referred to channel center) 51 858 MHz Power gain 0 3 dB Overall gain taper 2.5 dB Noise figure (tuners w/o remod) 5 dB CSO / CTB (acc. EN50083) -57 dBc RF-output return loss (referred to 75 Ω) 10 dB 9. Application information 9.1 Programming of tuner PLL The tuner control (frequency selection and band switching) is done via the I 2C bus. One address byte and four data bytes are needed to fully program the tuner. A PLL lock flag can be read from the tuner during 'READ' - mode. Four independent PLL addresses are available; which one is actually valid depends on the address select voltage that is connected to terminal 3. TD1300ALF tuners comply to the 5V I 2C – Bus specification.
