Programmable Clock Generator
5P49V5935
DATASHEET
Description
The 5P49V5935 is a programmable clock generator intended
for high performance consumer, networking, industrial,
computing, and data-communications applications.
Configurations may be stored in on-chip One-Time
Programmable (OTP) memory or changed using I2C
interface. This is IDTs fifth generation of programmable clock
technology (VersaClock® 5).
The 5P49V5935 by default uses an integrated 25MHz crystal
as input reference. It also has a redundant external clock
input. A glitchless manual switchover functions allows
selection of either one as mentioned above as input reference
during normal operation.
Two select pins allow up to 4 different configurations to be
programmed and accessible using processor GPIOs or
bootstrapping. The different selections may be used for
different operating modes (full function, partial function, partial
power-down), regional standards (US, Japan, Europe) or
system production margin testing.
The device may be configured to use one of two I2C
addresses to allow multiple devices to be used in a system.

Description
Differential clock input. Weak 100kohms internal pull-down.
Complementary differential clock input. Weak 100kohms internal pull-down.
No connect.
No connect.
Analog functions power supply pin. Connect to 1.8V to 3.3V. VDDA and VDDD
should have the same voltage applied.
Input clock select. Selects the active input reference source, when in Manual
switchover mode.
0 = Integrated crystal (default)
1 = CLKIN, CLKINB
CLKSEL Polarity can be changed by I2C programming as shown in Table 4.
Enables/disables the outputs (OE) or powers down the chip (SD). The SH bit
controls the configuration of the SD/OE pin. The SH bit needs to be high for
SD/OE pin to be configured as SD. The SP bit (0x02) controls the polarity of the
signal to be either active HIGH or LOW only when pin is configured as OE
(Default is active LOW.) Weak internal pull down resistor. When configured as
SD, device is shut down, differential outputs are driven high/low, and the single-
ended LVCMOS outputs are driven low. When configured as OE, and outputs are
disabled, the outputs can be selected to be tri-stated or driven high/low,
depending on the programming bits as shown in the SD/OE Pin Function Truth
table.
Configuration select pin, or I2C SDA input as selected by OUT0_SEL_I2CB.
Weak internal pull down resistor.
Configuration select pin, or I2C SCL input as selected by OUT0_SEL_I2CB.
Weak internal pull down resistor.
Output power supply. Connect to 1.8 to 3.3V. Sets output voltage levels for
OUT4/OUT4B.
Output Clock 4. Please refer to the Output Drivers section for more details.
Complementary Output Clock 4. Please refer to the Output Drivers section for
more details.
Complementary Output Clock 3. Please refer to the Output Drivers section for
more details.
Output Clock 3. Please refer to the Output Drivers section for more details.
Output power supply. Connect to 1.8 to 3.3V. Sets output voltage levels for
OUT3/OUT3B.
Complementary Output Clock 2. Please refer to the Output Drivers section for
more details.
Output Clock 2. Please refer to the Output Drivers section for more details.
Output power supply. Connect to 1.8 to 3.3V. Sets output voltage levels for
OUT2/OUT2B.
Complementary Output Clock 1. Please refer to the Output Drivers section for
more details.
Output Clock 1. Please refer to the Output Drivers section for more details.
Output power supply. Connect to 1.8 to 3.3V. Sets output voltage levels for
OUT1/OUT1B.
Digital functions power supply pin. Connect to 1.8 to 3.3V. VDDA and VDDB
should have the same voltage applied.
Power supply pin for OUT0_SEL_I2CB. Connect to 1.8 to 3.3V. Sets output
voltage levels for OUT0.
Latched input/LVCMOS Output. At power up, the voltage at the pin
OUT0_SEL_I2CB is latched by the part and used to select the state of pins 8
and 9. If a weak pull up (10Kohms) is placed on OUT0_SEL_I2CB, pins 8 and 9
will be configured as hardware select pins, SEL1 and SEL0. If a weak pull down
(10Kohms) is placed on OUT0_SEL_I2CB or it is left floating, pins 8 and 9 will
act as the SDA and SCL pins of an I2C interface. After power up, the pin acts as
a LVCMOS reference output which is the same frequency as the input reference.
At default, 25MHz integrated crystal is used so OUT0 will also be 25MHz.
Connect to ground pad.
