PIN DESCRIPTION
NOTES:
1. Outputs are user programmable to drive single-ended 3.3V LVTTL, differential LVDS, or differential LVPECL interface levels.
2. 3-level inputs are static inputs and must be tied to V
3. The JTAG (TDO, TMS, TCLK, TRST, and TDI) and I

Description
Input Clock
CRYSTAL_IN - Reference crystal input or external reference clock input
CRYSTAL_OUT -Reference crystal feedback
Multi-purpose inputs. Can be used for Frequency Control, SDAT(I
Multi-Purpose inputs. Can be used for Frequency Control, SCLK(I
Multi-Purpose inputs. Can be used for Frequency Control or TMS (JTAG)
Multi-Purpose inputs. Can be used for Frequency Control or as a suspend mode control
input (active HIGH).
Multi-Purpose inputs. Can be used for Frequency Control or TRST (JTAG)
Multi-Purpose inputs. Can be used for Frequency Control or input clock selector.
Enables/disables the outputs or powers down the chip. The SP bit (0x1C) controls the
polarity of the signal to be either active HIGH or LOW. (Default is active HIGH.)

Configurable clock output 1. Can also be used to buffer the reference clock.
Configurable clock output 2
Configurable clock output 3
Configurable clock output 4, Single-Ended or Differential when combined with OUT4
Configurable complementary clock output 4, Single-Ended or Differential when
combined with OUT4
Configurable clock output 5, Single-Ended or Differential when combined with OUT5
