FD5T Series Programmable
CMOS Clock Oscillator
November 2008
Description:
The FD5T series Programmable CMOS Clock Oscillator is a modular PLL-based low cost, highperformance oscillator. The frequency range is from 12KHz to 230MHZ.
The FD5T base frequency, as noted in the device part number, is established during manufacture and is
permanently fixed. For convenience, the divider for output OUT characteristics may be pre-programmed
at the factory, or field programmed.
The FD5T has a separate output supply pin, VDDOUT, for either 1.8, 2.5 or 3.3V output logic levels. The
device supply, VDD which provides power to all the internal circuits, is nominally 1.8V.
The deep M/N PLL divider ratio allows the generation of zero-ppm clocks for applications such as WLAN,
BlueTooth, Ethernet, USB, IEEE1394, etc. from the base frequency.
The PLL supports Spread Spectrum Clocking (SSC). SSC may be programmed to be either centerspread or down-spread. This is an important technique to reduce electro-magnetic interference (EMI).
The device supports non-volatile eePROM programming for easy customization of the device. As
shipped, the device is pre-programmed. Standard combinations are denoted by three characters in the
device part number. However, the FD5T may be reprogrammed to a different configuration.
Reprogramming may be either prior to assembly, or in-circuit via a 2-wire SDA/SCL I2C bus. In-circuit
programming is not allowed if the VCXO function is needed.
Two programmable control inputs, S1 and S2, may be used to control various aspects of FD55T operation
including selection of alternative frequency set(s), selection of SSC functionality, output tri-state and
power-down.
Reference Oscillator
The Reference Oscillator is an AT cut quartz crystal based oscillator. This oscillator is very similar to the
Pletronics SM77xxH product oscillator. This signal is the lowest jitter and can be an output or can be
divided down by the Divider #1. The user may specify any frequency between 12MHz and 32MHz for
this reference. All output frequencies are derived from (referenced to) this Reference Oscillator.
The VCXO input has a limited voltage range, the VCXO is associated with the internal 1.8V core. A
resistor in series with the Vcontrol input will permit interfacing to 3.3V analog circuits, the voltage range
that changes the frequency will still be limited but the larger voltages swings will not cause problems.
The VCXO function is only enabled (internally connected) if the part number indicates a VCXO
specification. When the VCXO function is enabled the I2C programming mode will be disabled.
PLL Multipliers
The PLL Multiplier can multiply the Reference Oscillator frequency from 1 (bypass mode) to any value
that is <=230MHz (the lowest frequency is the Reference Oscillator frequency).
The PLL Multipliers can have two setup options, 0 or 1, depending on which option is chosen and set by
the Sx control signals and the user’s definitions are stored in eePROM.

FD5T Series Programmable
CMOS Clock Oscillator

Each PLL has its individual Spread Spectrum (SS) function that can be enabled. This permits the
modulation of the output frequency by a user-set amount. The modulation can be centered on the
output frequency or down side only. Which of the 1 of 8 SS settings is being used is set by the Sx input
and the user definition. The value is a percentage of the output frequency that will be modulated.

Divider Section
The dividers operate on the output of the PLL. The divider on the PLL can divide by 1 through 127, the
value is user defined. There is only 1 setting allowed per divider. These are not set by the Sx input
state.
The dividers add very little jitter to the output signals.
Multiplexers
MUX #1 selects the input to the Divider #1, this can be the reference oscillator signal or the output from
PLL Multiplier #1. MUX #3 connect various divider outputs to the output buffer.
The device can make only one of the setting of connections shown in the block diagram (only one
pattern stored in eePROM).
Output Buffer
The output buffer can have 3 modes of operation:
1) Tri State
2) Active Low
3) The signal output of the Multiplexer
There can be two options stored for the Output Buffer, State 0 and State 1. The four Sx input settings
can have assigned one of the two Output Buffer states for each of Output Buffer sets.
Control Inputs
The two inputs, S1/SDA and S2/SCL can be configured in two ways.
1) Used as 2 user inputs to permit up to 4 states, Sx input setting.
2) The SDA and SCL become clock and data inputs to write to the FD5T internal setting memory.
The interface follows the I2C protocol. If the SDA and SCL are not set then the internal eePROM
sets the operation. (Not allowed if the VCXO function is specified.)

Data is taken under the following conditions: 1-PLL; 27MHz Crystal, (measured at Out3).
Frequency Tolerance:
For the FD5115T and the FD5110T devices, Pletronics recommends that the tight
tolerance be required on the PLL outputs only. In this case the reference frequency
output would only achieve ±25ppm tolerance. This will reduce the cost of the device.
