ISDB-T Single-Segment Low-IF Tuners
Detailed Description
All registers must be written after power-up and no ear-
lier than 100µs after power-up.
Register Descriptions
The MAX2160/EBG include eight programmable regis-
ters and two read-only registers. The eight programma-
ble registers include a test register, a PLL register, a
VCO register, a control register, a XTAL divide register,
an R-divider register, and two N-divider registers. The
read-only registers include two status registers.

FUNCTION
TUN[2:0]
7, 6, 5
Set the baseband bandpass filter center frequency. This filter’s center frequency
is trimmed at the factory, but may be manually adjusted by clearing the FLTS bit
and programming the TUN[2:0] bits as follows:
000 = 0.75 x fO
001 = 0.80 x fO
000
010 = 0.86 x fO
011 = 0.92 x fO
100 = fO (nominal center frequency of 571kHz)
101 = 1.08 x fO
110 = 1.19 x fO
111 = 1.32 x fO
FLTS
4
Selects which registers set the baseband bandpass filter center frequency.
1
1 = selects internal factory-set register
0 = selects manual trim register TUN[2:0]
