• Description: 3.3V EEPROM PROGRAMMABLE CLOCK GENERATOR
• Manufacturer: Integrated Device Technology, Inc.

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

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.)
I
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
Configurable complementary clock output 5, Single-Ended or Differential when
combined with OUT5
Configurable clock output 6
Multi-Purpose Output. Can be programmed to use as PLL LOCK signal, LOSS_LOCK
or TDO in JTAG mode
