SLAS564F – AUGUST 2007 – REVISED MARCH 2010
S1/SDA and S2/SCL pins of the CDCE937/CDCEL937 are dual function pins. In default configuration they are
defined as SDA/SCL for the serial interface. They can be programmed as control-pins (S1/S2) by setting the
relevant bits in the EEPROM. Note that the changes to the Control register (Bit [6] of Byte [02]) have no effect
until they are written into the EEPROM.
Once they are set as control pins, the serial programming interface is no longer available. However, if VDDOUT is
forced to GND, the two control-pins, S1 and S2, temporally act as serial programming pins (SDA/SCL).
S0 is not a multi-use pin, it is a control pin only.
DEFAULT DEVICE SETTING
The internal EEPROM of CDCE937/CDCEL937 is preconfigured as shown in Figure 6. (The input frequency is
passed through to the output as a default). This allows the device to operate in default mode without the extra
production step of program it. The default setting appears after power is supplied or after power-down/up
sequence until it is re-programmed by the user to a different application configuration. A new register setting is
programmed via the serial SDA/SCL Interface.
Figure 6. Default Device Setting
Table 4 shows the factory default setting for the Control Terminal Register (external control pins). In normal
operation, all 8 register settings are available, but in the default configuration only the first two settings (0 and 1)
can be selected with S0, as S1 and S2 configured as programming pins in default mode.

In default mode or when programmed respectively, S1 and S2 act as serial programming interface, SDA/SCL. They do not have any
control-pin function but they are internally interpreted as if S1=0 and S2=0. S0, however, is a control-pin which in the default mode
switches all outputs ON or OFF (as previously predefined).
