TDA6650TT; TDA6651TT
5 V mixer/oscillator and low noise PLL synthesizer
Linked to this noise improvement, some disturbances may become visible while they were
not visible because they were hidden into the noise in analog dedicated applications and
circuits.
This is especially true for disturbances coming from the I2C-bus traffic, whatever this traffic
is intended for the MOPLL or for another slave on the bus.
To avoid this I2C-bus crosstalk and be able to have a clean noise spectrum, it is necessary
to use a bus gate that enables the signal on the bus to drive the MOPLL only when the
communication is intended for the tuner part (such a kind of I2C-bus gate is included into
the NXP terrestrial channel decoders), and to avoid unnecessary repeated sending of the
same information.
8.
I2C-bus protocol
The TDA6650TT; TDA6651TT is controlled via the two-wire I2C-bus. For programming,
there is one device address (7 bits) and the R/W bit for selecting read or write mode. To be
able to have more than one MOPLL in an I2C-bus system, one of four possible addresses
is selected depending on the voltage applied to address selection pin AS (see Table 8).
The TDA6650TT; TDA6651TT fulfils the fast mode I2C-bus, according to the NXP I2C-bus
specification, except for the timing as described in Figure 4. The I2C-bus interface is
designed in such a way that the pins SCL and SDA can be connected to 5 V, 3.3 V
or to 2.5 V pulled-up I2C-bus lines, depending on the voltage applied to pin BVS (see
Table 5).
8.1 Write mode; R/W=0
After the address transmission (first byte), data bytes can be sent to the device (see
Table 6). Five data bytes are needed to fully program the TDA6650TT; TDA6651TT. The
I2C-bus transceiver has an auto-increment facility that permits programming the device
within one single transmission (address + 5 data bytes).
The TDA6650TT; TDA6651TT can also be partly programmed on the condition that the
first data byte following the address is byte 2 (divider byte 1) or byte 4 (control byte 1). The
first bit of the first data byte transmitted indicates whether byte 2 (first bit = 0) or byte 4
(first bit = 1) will follow. Until an I2C-bus STOP condition is sent by the controller, additional
data bytes can be entered without the need to re-address the device. The fractional
calculator is updated only at the end of the transmission (STOP condition). Each control
byte is loaded after the 8th clock pulse of the corresponding control byte. Main divider
data are valid only if no new I2C-bus transmission is started (START condition) during the
computation period of 50
µs.
Both DB1 and DB2 need to be sent to change the main divider ratio. If the value of the
ratio selection bits R2, R1 and R0 are changed, the bytes DB1 and DB2 have to be sent in
the same transmission.
