Product data sheet
1. General description
The TDA18218HN is a Silicon Tuner IC designed for digital terrestrial (DVB-T) TV
reception. The TDA18218HN integrates the overall tuning function, including selectivity
and provides a low-IF output signal.
The TDA18218HN uses integrated IF filters to support 6 MHz, 7 MHz or 8 MHz channel
bandwidths. The TDA18218HN requires only one single 16 MHz crystal for clock
generation. A clock signal is available on crystal oscillator output pins (XTO_P / XTO_N)
to synchronize the channel decoder.
The TDA18218HN is a low cost Silicon Tuner targeting digital terrestrial applications. The
TDA18218HN matches the performance of the conventional can tuners. Additionally, the
following benefits can be stated:
• Easy on-board integration
• Drastically reduces:
– the size of the tuner function
– the power consumption

8. Functional description
The RF input signal is driven to a low-noise amplifier. It is then amplified and fed to the
image rejection mixer. The mixer down-converts the RF signal to a low IF frequency, which
depends on channel bandwidth (standard IF filters are implemented for 6 MHz, 7 MHz

and 8 MHz channel bandwidths). The TDA18218HN requires a single 16 MHz crystal for
clock generation, a 16 MHz differential sine wave clock reference is available to drive a
channel decoder.
8.1 AGC1 stage
The TDA18218HN embeds 2 different RF amplifiers with internal gain control.
The first stage, AGC1, behaves like a LNA (Low noise amplifier); its gain can take 4
different values (15 dB, 12 dB, 9 dB and 6 dB). Purpose of this amplifier is to ensure a low
noise figure for the tuner.
In order to optimize noise and linearity performances an internal level detector selects the
appropriate gain:
• If the signal level at the tuner is low, the gain is set to the maximum value (15 dB).
• If the signal level at the tuner input is high, the gain is set to the minimum value (6 dB).
• In between the gain is set to an intermediate value 12 dB or 9 dB.
The strategy of the level detection is a proprietary algorithm from NXP, managed by the
driver.
It should be noted that:
1. The level detector measures the signal level within the complete RF frequency range,
i.e. from 50 MHz to 870 MHz. Consequently, AGC1 gain is adapted to the complete
RF power. If a strong signal is present at the tuner input, it will determine AGC1 gain
(even if it is not the wanted signal). This concept prevents the tuner from overloading.
2. The level control is always operating.
8.2 AGC2 stage
The second stage, AGC2, is also an amplifier with a gain controlled thanks to a level
detector.
The gain is controlled between −12 dB and +16.4 dB, it is adapted by steps of 0.2 dB.
It should be noted that:
1. The level control is always operating. Consequently, this amplifier is responsible for
adapting the daily level changes.
2. The level detector measures the signal level within the complete RF frequency range
(same as AGC1)
The strategy of the level detection is a proprietary algorithm from NXP, managed by the
driver.
8.3 IF AGC
Finally, in order to adapt the tuner output level, a last amplifier is used (IF AGC). This
amplifier delivers the appropriate level to the DVB-T channel decoder. The output level is
therefore controlled thanks to the DC voltage applied on VIFAGC pin. This voltage is
commonly delivered by the channel decoder.

It should be noted that the level control is always operating.
The strategy of the level detection has to be adapted for each type of channel decoder. It
must be defined to satisfy ADC sampling (minimum level, ADC headroom).
All AGC amplifiers are controlled independently.
8.4 Power-down mode
The TDA18218HN can be programmed in Standby mode. The following blocks are turned
off when programming a power-down:
•
•
•
•
•
AGC2 and its level detector
BP filter
Mixer and VCO
IF selectivity LPFc
IF AGC
Remaining functions are:
• Loop-Through
• 16 MHz clock output (to drive a channel decoder)
• I2C-bus Core (to wake-up the IC later on)
9. Control interface
9.1 I2C-bus format, write and read mode
I2C-bus uses two pins (SDA and SCL) to transfer information between devices connected
to the bus. The SDA pin provides bidirectional data transfer. While the SCL pin provides
the timing sequences. Data can be read and written as follows:
Write mode:
• Any register can be written to using its subaddress
• Any following (contiguous) registers can be written using the subaddress of the first
register
Read mode:
• The read after Restart mode is not allowed. In addition, registers cannot be read using
the subaddress of the register. However, registers can be read as follows:
– from 00h to 16h
– from 00h to 27h
– from 00h to 3Ah
– from 00h to any register subaddress, if MSB = 1 for the next register

The programmable module address bits MA[1:0] allow up to four tuners to be addressed
in one system. Bits MA[1:0] are programmed by applying a specific voltage (VAS) to pin
AS. The relationship between the status of bits MA[1:0] and the voltage applied to pin AS
is shown in Table 5.

9.3 Crystal buffer output
TDA18218HN embeds a Xtal oscillator and a buffer to drive another IC. The buffer can be
configured through register XTOUT (I2C-bus sub address 19h). This buffer has been
designed to be AC coupled. This output can be used in differential or sinusoidal mode
(using XTO_N and XTO_P pins) or in asymmetrical or square mode (just leaving one pin
open).
It should be noted that TDA18218HN specification refers to differential output with no
load.
