General Description
The MAX2163 low-IF tuner IC is designed for use in
1-segment ISDB-T applications. The MAX2163 directly
converts UHF band signals to a low-IF using a broad-
band I/Q downconverter. The operating frequency
range covers the UHF band from 470MHz to 806MHz.
The MAX2163 includes LNAs, RF variable gain ampli-
fiers, I and Q downconverting mixers, a baseband vari-
able gain amplifier, and a low-IF filter. The MAX2163’s
variable gain amplifiers provide in excess of 100dB of
control range.
The MAX2163 also includes fully monolithic VCOs as
well as a complete frequency synthesizer including an
on-chip crystal oscillator and output buffer. The device
operates with a crystal from 32MHz to 36MHz.
The MAX2163 features a 2-wire I2C-compatible serial-
control interface. A low-power standby mode is avail-
able that shuts down the signal path leaving the control
interface and register circuits active. Additionally, an
external pin can shut down the entire device.
The MAX2163 is specified for operation in the extended
-40°C to +85°C temperature range and is available
in a 5mm x 5mm x 0.8mm, 28-pin thin QFN, lead-free
plastic package with exposed paddle (EP).

Register Descriptions
The MAX2163 includes 16 programmable registers and
2 read-only registers. Note:All programmable registers
must be written no earlier than 100µs after device power-
up or recovery from a brownout event (i.e., when VCC
drops below 1V). Follow up by rewriting the registers
needed for channel/frequency programming (i.e., regis-
ters 00–08) or simply rewrite all registers. The default val-
ues listed in Tables 1–15 are provided for informational
purposes only. The user must write all required register
values, including “factory use only” values.

0 = Charge-pump current is set manually through the CP[1:0] bits.
1 = Charge-pump current is automatically selected. Also requires ADE, ADL,
and VAS bits to be programmed to 1.
ADL 3 0
Enables or disables the VCO tuning voltage ADC latch.
0 = Disables the ADC latch.
1 = Latches the ADC value.
ADE 2 0
Enables or disables VCO tuning voltage ADC.
0 = Disables ADC read.
1 = Enables ADC read.
LTC[1:0] 1, 0 11
Sets the VCO autoselect wait time.
00 = 14336/fXTAL.
01 = 24576/fXTAL.
10 = 34816/fXTAL.
11 = 45056/fXTAL.

(0 = LSB)DEFAULTFUNCTION 7 0 Factory use only. Must be programmed to 0 upon power-up.
VCO[1:0] 6, 5 01
Controls which VCO band is activated when using manual VCO programming
mode. This also serves as the starting point for VCO autoselect mode when
VASS = 0.
00 = Select VCO-0.
01 = Select VCO-1.
10 = Select VCO-2.
11 = Not used.
