4 / 25 page IDT5P49EE802 VERSACLOCK® LOW POWER CLOCK GENERATOR EEPROM CLOCK GENERATOR IDT™ VERSACLOCK® LOW POWER CLOCK GENERATOR 4 IDT5P49EE802 REV C 061810 Note 1: Outputs are user programmable to drive single-ended 1.8V/2.5V/3.3V LVTTL. Alway completely power up VDD and VDDx prior to applying VDDO power. Always power up device into “Active” configuration modes, prior to asserting Power Down/Sleep mode SEL=00. Note 2: Default configuration CLK4=Buffered MHz Reference output and CLK2=Buffered 32.768kHz output. All other outputs are off. OUT2 13 O Adjustable Configurable clock output 2. Single-ended output voltage levels are register controlled by either VDDO1, VDDO2 or VDDO3. SEL1 14 I LVTTL Configuration select pin. Weak internal pull down resistor. OUT1 15 O Adjustable Configurable clock output 1. Single-ended output voltage levels are register controlled by either VDDO1, VDDO2 or VDDO3. VDD 16 Power Device power supply. Connect to 1.8V. VDD 17 Power Device power supply. Connect to 1.8V. OUT0 18 O Adjustable Configurable clock output 0. Single-ended output voltage levels are register controlled by either VDDO1, VDDO2 or VDDO3. VDDO3 19 Power Device power supply. Connect to 1.8 to 3.3V. Using register settings, select output voltage levels for OUT0-OUT6. SCLK 20 I LVTTL I2C clock. OUT6B 21 O Adjustable Configurable clock output 6B. Output voltage level is controlled by VDDO1. OUT6A 22 O Adjustable Configurable clock output 6B. Output voltage level is controlled by VDDO1. SDA 23 I/O LVTTL Bidirectional I2C data. VDD 24 Power Device power supply. Connect to 1.8V. VDD 25 Power Device power supply. Connect to 1.8V. GND 26 Power Connect to Ground. XIN/ REF 27 I LVTTL MHz CRYSTAL_IN -- Reference crystal input or external reference clock input. XOUT 28 O LVTTL MHz CRYSTAL_OUT -- Reference crystal feedback. EP -- Exposed thermal pad should be externally connected to ground. Pin Name Pin # I/O Pin Type Pin Description |
