ISDB-T Single-Segment Low-IF Tuners
General DescriptionThe MAX2160/EBG tuner ICs are designed for use in
Japanese mobile digital TV (ISDB-T single-segment)
applications. The devices directly convert UHF band
signals to a low-IF using a broadband I/Q downconvert-
er. The operating frequency range extends from
470MHz to 770MHz.
The MAX2160/EBG support both I/Q low-IF interfaces
as well as single low-IF interfaces, making the devices
universal tuners for various digital demodulator IC
implementations.
The MAX2160/EBG include an LNA, RF variable-gain
amplifiers, I and Q downconverting mixers, low-IF variable-
gain amplifiers, and bandpass filters providing in excess of
42dB of image rejection. The parts are capable of operat-
ing with either high-side or low-side local oscillator (LO)
injection. The MAX2160/EBG’s variable-gain amplifiers pro-
vide in excess of 100dB of gain-control range.
The MAX2160/EBGalso include fully monolithic VCOs
and tank circuits, as well as a complete frequency syn-
thesizer. The devices include a XTAL oscillator as well
as a separate TCXO input buffer. The devices operate
with XTAL/TCXO oscillators from 13MHz to 26MHz
allowing the shared use of a VC-TCXO in cellular hand-
set applications. Additionally, a divider is provided for
the XTAL/TCXO oscillator allowing for simple and low-
cost interfacing to various channel decoders.
The MAX2160/EBGare specified for operation from
-40°C to +85°C and available in a 40-pin (6mm x 6mm)
thin QFN lead-free plastic package with exposed pad-
dle (EP), and in a 3.175mm x 3.175mm lead-free wafer-
level package (WLP).

MAX2160/MAX2160EBG
ISDB-T Single-Segment Low-IF Tuners
Detailed DescriptionAll registers must be written after power-up and no ear-
lier than 100µs after power-up.
Register DescriptionsThe 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.

BIT NAMEBIT LOCATION
(0 = LSB)
RECOMMENDED
DEFAULTFUNCTIONTUN[2:0]7, 6, 5000
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
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
FLTS41
Selects which registers set the baseband bandpass filter center frequency.
1 = selects internal factory-set register
0 = selects manual trim register TUN[2:0]

RECOMMENDED
DEFAULTFUNCTIONMXSD30
Used for factory trimming of the baseband filters.
1 = disables the quadrature mixers for filter tuning
0 = enables the quadrature mixers
D[2:0]2, 1, 0000
Control diagnostic features as follows:
000 = normal operation
001 = force charge-pump source current
010 = force charge-pump sink current
011 = force charge-pump high-impedance state
100 = power-detector RMS voltage at PWRDET
101 = N-divider output at TEST pin
110 = R-divider output at TEST pin
111 = local oscillator output at TEST pin

RECOMMENDED
DEFAULTFUNCTIONCP[1:0]7, 611
Set the charge-pump current.
00 = ±1.5mA
01 = ±2mA
10 = ±2.5mA
11 = ±3mA
CPS51
Sets the charge-pump current selection mode between automatic and manual.
0 = charge-pump current is set manually through the CP[1:0] bits
1 = charge-pump current is automatically selected based on ADC read values
in both VAS and manual VCO selection modes
EPB41
Controls the charge-pump prebias function.
0 = disables the charge-pump prebias function
1 = enables the charge-pump prebias function
RPD30
Sets the prebias on-time control from reference divider.
0 = 280ns
1 = 650ns
NPD20
Sets the prebias on-time control from VCO/LO divider.
0 = 500ns
1 = 1000ns
TON10
Sets the charge-pump on-time control.
0 = 2.5ns
1 = 5ns
VAS01
Controls the VCO autoselect (VAS) function.
0 = disables the VCO autoselect function and allows manual VCO selection
through the VCO[1:0] and VSB[2:0] bits
1 = enables the on-chip VCO autoselect state machine

DEFAULTFUNCTIONVCO[1:0]7, 611
Control which VCO is activated when using manual VCO programming mode.
This will also serve as the starting point for the VCO autoselect mode.
00 = select VCO 0
01 = select VCO 1
10 = select VCO 2
11 = select VCO 3
VSB[2:0]5, 4, 3011
Select a particular sub-band for each of the on-chip VCOs. Together with the
VCO[2:0] bits a manual selection of a VCO and a sub-band can be made. This
will also serve as the starting point for the VCO autoselect mode.
000 = select sub-band 0
