General description
The PCA9527 is a 3-channel bidirectional open-drain bus buffer for Display Data Control
(DDC) clock, data and Consumer Electronic Control (CEC) for HDMI application. The
device has two power supply pins to allow voltage level shift from 2.7 V to 5 V, and a
rise time accelerator on port A of each DDC clock and data for driving longer cable (up
to 18 meters or 1400 pF reliably without violating the bus rise time). The 5 V tolerant
CEC channel is internally connected to VCC(B) and has no rise time accelerator. The CEC
channel can be used as an interrupt or reset.
2
While retaining all the operating modes and features of the I C-bus system during the
2
level shift, it also permits extension of the I C-bus by providing bidirectional buffering for
data (SDA), clock (SCL), and CEC. Using the PCA9527 enables the system designer
to isolate bus capacitance to meet HDMI DDC version 1.3 distance specification.
The SDAx and SCLx pins are overvoltage tolerant and are high-impedance when the
PCA9527 is unpowered. The port B drivers (SDAB, SCLB, CECB) with static level
offset behave much like the drivers on the PCA9515 device, while the SDAA and SCLA
drivers integrate the rise time accelerator, sink more current and eliminate the static
offset voltage. The CECA driver has the same current and static offset voltage features
as the SDAA and SCLA, but it does not have the rise time accelerator and is powered
and referenced to VCC(B). This results in a LOW on the port B translating into a nearly
0 V LOW on port A, providing zero offset. The static level offset design of the port B
I/O drivers prevent them from being connected to another device that has rise time
accelerator including the PCA9507 (port B), PCA9510, PCA9511, PCA9512, PCA9513,
PCA9514, PCA9515, PCA9516A, PCA9517 (port B), or PCA9518A. Port A of two or
more PCA9527s can be connected together, however, to allow a star topography with
port A on the common bus, and port A can be connected directly to any other buffer with
static or dynamic offset voltage. Multiple PCA9527s can be connected in series, port A
to port B, with no build-up in offset voltage with only time of flight delays to consider. Rise
time accelerators on the SDAA and SCLA pins are turned on when input threshold is
above 0.3VCC(A). The PCA9527 SDA and SCL drivers are not enabled unless VCC(A) and
VCC(B) are above 2.7 V. The EN pin can also be used to turn the drivers on and off under
system control. Caution should be observed to only change the state of the enable pin
when the bus is idle. The output pull-down on the port B internal buffer LOW is set for
approximately 0.5 V, while the input threshold of the internal buffer is set about 70 mV
lower (0.43 V). When the port B I/O is driven LOW internally, the LOW is not recognized
as a LOW by the input. This prevents a lock-up condition from occurring.

Functional description
Refer to Figure 1.
The PCA9527 consists of 3 channels of bidirectional open-drain I/Os specifically
designed to support up-translation/down-translation between low voltages (as low as 2.7
2
V) and a 3.3 V or 5 V I C-bus and SMBus. The device contains a rise time accelerator,
specifically on port A of the SCLA and SDAA that enables the device to drive a long
2
cable or a heavier capacitive load for DDC, I C-bus and SMBus applications. With dual
supply rails, the device translates from voltage ranges 2.7 V to 5.5 V down to a voltage
as low as 2.7 V without degradation of system performance. Unlike the SDAA and
SCLA, the CECA is powered by the VCC(B) and does not have a rise time accelerator,
but is similar in that its port A has normal I/O and port B static level offset. All I/Os are
overvoltage tolerant to 5.5 V even when the device is un-powered (VCC(B) and/or VCC(A) =
0 V).
The PCA9527 includes a power-up circuit that keeps the SDA and SCL output drivers
turned off until VCC(A) and VCC(B) rise above 2.7 V. The CECA output drivers are turned
OFF until VCC(B) rises above 2.7 V. VCC(A) and VCC(B) can be applied in any sequence at
power-up.

Figure 3. Port A and port B I/O levels
When port B falls first and goes below 0.3VCC(B) the port A driver is turned on and port
A pulls down to 0 V. As port A falls below 0.3VCC(A) the port B pulls down to about 0.5 V.
The external port B driver must drive the port B to a LOW that is ≤ 0.4 V or else it is not
possible to know who is driving the port A LOW. The PCA9527 direction control assumes
that port A is controlling the part unless port B falls below 0.4 V. When the port B voltage
is ≤ 0.4 V the port A driver of the PCA9527 is on and holds port A down to nearly 0 V.
As the port B voltage rises because the external driver turns off, the port B voltage rises
up to ~0.5 V because port A is LOW; once port B rises to ~0.5 V the port A pull-down
driver turns off. Then port A rises with a rise time determined by the RC of port A when it
crosses the port A threshold ~0.3VCC(A) the port B driver is turned off and the rising edge
accelerator is turned on, which causes a faster rising edge until it reaches the turn-off

point for the rising edge accelerator ~0.7VCC(A). Then it continues to rise at the slower
rate determined by the RC of port A. When the port B driver turns off, port B rises with the
RC of port B.
VCC(A) powers the 0.3VCC(A) reference for SCLA and SDAA as well as the port A power
good detect circuit. VCC(B) powers the rest of the chip including the port B I/Os, the CEC
I/Os, and the support functions. Figure 3 illustrates the threshold and I/O levels for port A
and port B.
6.1 Enable
The EN pin is active HIGH with an internal ~100 kΩ pull-up to VCC(B) and allows the
user to select when the buffer is active. The enable pin puts the PCA9527 in a powerdown state when it is disabled, so that there is a recovery delay and a lower power-down
power. This can be used to isolate the line when the HDMI DDC transmitter or receiver
is not ready, or from a badly behaved target on power-up until after the system power2
up reset. It should never change state during an I C-bus operation, because disabling
during a bus operation will hang the bus and enabling part way through a bus cycle could
2
confuse the I C-bus parts being enabled. The enable pin should only change state when
the global bus and the buffer port are in an idle state, to prevent system failures.
6.2 Rise time accelerators
PCA9527 has rise time accelerators on port A of SCL and SDA only; the CECA pin
does not have a rise time accelerator. During port A positive bus transitions a current
source is switched on to quickly slew the SDAA and SCLA lines HIGH once the input
level of 0.3VCC(A) is exceeded for the PCA9527 and turns off as the 0.7VCC(A) voltage is
approached.
6.3 Resistor pull-up value selection
6.3.1 Port A (SDAA and SCLA)
SDAA and SCLA are open-drain I/O that have rise time accelerators and strong pulldown. When the inputs transition above 0.3VCC(A), the rise time accelerator activates and
2
boosts the pull-up current during rising edge to meet the I C-bus rise time specification
when the device drives a long cable or heavier capacitance load. The strong pull-down
enables the output to drive to nearly zero voltage for logic LOW. The selection for pullup resistors are defined in the HDMI DDC specification shown in Table 4. For HDMI
transmitter applications like digital video player, recorder, or set-top box, the pull-up
resistor is in the range of 1.5 kΩ to 2 kΩ. For HDMI receiver applications like in LCD TV
or video card, the pull-up resistor is 47 kΩ on the SCLA line, and there is no pull-up on
the SDAA line. Please refer to Table 4, Figure 6 and Figure 7 for more details. Figure 4
shows the port A pull-up resistor values (in kΩ) versus capacitance load (in nF) for 5 V
2
supply voltage complied with 1 μs rise time per I C-bus Standard-mode specification.
The graph contrasts a shaded and unshaded region. Any resistor value chosen within the
unshaded region would comply with 1 μs rise time, while any value chosen in the shaded
region would not.

6.3.2 Port A (CECA)
CECA does not have a rise time accelerator, but has a standard open-drain I/O. In
addition to incurring no offset voltage, it has edge rate control and a lower capacitance
than those of standard discrete MOSFET, and isolates the input/output capacitance. It is
designed for a lower speed channel for consumer electronic control (less than 10 kHz) or
general purpose interrupt or reset over long cable.
CECA does not have internal pull-up. The pull-up resistor is calculated using standard
2
I C-bus pull-up resistor formula, as shown in Section 6.3.3CECB)".
6.3.3 Port B (SDAB, SCLB, CECB)
2
SDAB and SCLB are standard I C-bus with static level offset that has no rise time
accelerator. The static level offset produces an output LOW of 0.5 V (typical) at 6 mA.
2
As with the standard I C-bus system, pull-up resistors are required to provide the logic
HIGH levels. The size of these pull-up resistors depends on the system requirement, and
should meet the current sinking capability of the device that drives the buffer, as well as
that of the buffer. The minimum and maximum pull-up resistors are determined and the
pull-up resistor’s value is chosen to be within the minimum and maximum range.
Using Equation 1, calculate the minimum pull-up resistor value:

Where:
RPU(min) is the minimum pull-up resistor value for the open-drain SCLB and SDAB.

Vpu(max) is the maximum supply rail of the pull-up resistor and should not exceed 5.5
V.
0.4 V is the maximum VOL of the device that drives the buffer on logic LOW.
IOL(max) at VOL = 0.4 V is the maximum sink current of the device that drives the buffer
on logic LOW.
The maximum pull-up resistor should also be sized such that the RC time constant meets
2
the standard I C-bus rise time, which is 1 μs for Standard-mode (100 kHz) or 300 ns for
2
Fast-mode (400 kHz). DDC bus complies with the I C-bus Standard-mode and operates
below 100 kHz, and maximum rise time is 1 μs using a simplified RC equation.
Using Equation 2, calculate the maximum pull-up resistor value:
(2)
Where:
RPU(max) is the maximum allowable pull-up resistor on the SCLB and SDAB in order to
2
meet the I C-bus rise time specification.
CL(max) is the maximum allowable capacitance load (include the capacitance of driver,
the line, and the buffer) in order to meet the rise time specification.
tr is the rise time specified as 1 μs (for bus speed 100 kHz or lower) and 300 ns (for
bus speed 400 kHz or lower).
The chosen pull-up resistor RPU is: RPU(min) ≤ RPU ≤ RPU(max).

Application design-in information
A typical application is shown in Figure 5. In this example, the system controller is
2
running on a 3.3 V I C-bus while the target is connected to a 5 V bus. Both buses run
at 400 kHz. Controller devices can be placed on either bus. HDMI DDC applications
for DVD/R and LCD TV are shown in Figure 6 and Figure 7, respectively. In these
applications the HDMI transmitter or receiver is 3.3 V, while the DDC line is 5 V,
PCA9527 behaves like a voltage level shift, a buffer and long cable bus extender to
ensure signal integrity for accessing the EDID on the DDC line.

According to Figure 5, when port A of the PCA9527 is pulled LOW by a driver on the I Cbus, a comparator detects the falling edge when it goes below 0.3VCC(A) and causes the
internal driver on port B to turn on, causing port B to pull down to about 0.5 V. When port
B of the PCA9527 falls, first a CMOS hysteresis type input detects the falling edge and
causes the internal driver on port A to turn on and pull the port A pin down to ground.
In order to illustrate what would be seen in a typical application, refer to Figure 11 and
Figure 12.
If the bus controller in Figure 5 were to write to the target through the PCA9527,
waveforms shown in Figure 11 would be observed on the A bus. This looks like a normal
2
I C-bus transmission except that the HIGH level may be as low as 2.7 V, and the turn on
and turn off of the acknowledge signals are slightly delayed.
The controller drives the B bus to ground or lets it float to VCC(B) as it sends data to the
th
target at the falling edge of the 8 clock, controller releases SDAB on the B bus and
target pulls SDAA on the A bus to ground, causing the PCA9527 to pull SDAB on the B
th
bus to 0.5 V. At the falling edge of the 9 clock, the controller again drives the B bus and
target releases the A bus.
Multiple PCA9527 port A sides can be connected in a star configuration (Figure 8),
allowing all nodes to communicate with each other.
Multiple PCA9527s can be connected in series (Figure 9) as long as port A is connected
2
to port B. I C-bus target devices can be connected to any of the bus segments. The
number of devices that can be connected in series is limited by repeater delay/time-offlight considerations on the maximum bus speed requirements.

Times are specified with loads of 1.35 kΩ pull-up resistance and 57 pF load capacitance on port B, and 450 Ω pull-up resistance and 57 pF load
capacitance on port A. Different load resistance and capacitance will alter the RC time constant, thereby changing the propagation delay and transition
times.
Pull-up voltages are VCC(A) on port A and VCC(B) on port B.
Typical values were measured with VCC(A) = 3.3 V at Tamb = 25 °C, unless otherwise noted.
The tPLH delay data from port B to port A is measured at 0.5 V on port B to 0.3VCC(A) on port A.
The proportional delay data from port A to port B is measured at 0.3VCC(A) on port A to 0.3VCC(B) on port B.
The enable pin, EN, should only change state when the global bus and the repeater port are in an idle state.
If the VCC(A) ramp up is fast, then the trec(pd-act) time must be allowed before the inputs are switched. If the supply ramp up is slow, the channels may be
connected even before the final supply voltage is reached.
If the VCC(B) ramp up is fast, then the trec(pd-act) time must be allowed before the inputs are switched. If the supply ramp up is slow, the channels may be
connected even before the final supply voltage is reached.

13 Soldering of SMD packages
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note AN10365 “Surface mount reflow
soldering description”.
13.1 Introduction to soldering
Soldering is one of the most common methods through which packages are attached
to Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides
both the mechanical and the electrical connection. There is no single soldering method
that is ideal for all IC packages. Wave soldering is often preferred when through-hole
and Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is
not suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.
13.2 Wave and reflow soldering
Wave soldering is a joining technology in which the joints are made by solder coming
from a standing wave of liquid solder. The wave soldering process is suitable for the
following:
• Through-hole components
• Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solder lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.
The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solderable.
Key characteristics in both wave and reflow soldering are:
•
•
•
•
•
•
Board specifications, including the board finish, solder masks and vias
Package footprints, including solder thieves and orientation
The moisture sensitivity level of the packages
Package placement
Inspection and repair
Lead-free soldering versus SnPb soldering
13.3 Wave soldering
Key characteristics in wave soldering are:
• Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
• Solder bath specifications, including temperature and impurities
13.4 Reflow soldering
Key characteristics in reflow soldering are:

• Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads
to higher minimum peak temperatures (see Figure 19) than a SnPb process, thus
reducing the process window
• Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
• Reflow temperature profile; this profile includes preheat, reflow (in which the board
is heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enough for the solder to make reliable solder joints (a solder
paste characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in accordance with Table 8
and Table 9

Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reflow
soldering, see Figure 19.
