3-Channel High-Performance TCXO/LVCMOS
Clock Buffer Family
5PB12xx
DATASHEET
Description
The 5PB12xx is a high-performance TCXO/LVCMOS clock
fanout buffer family with individual OE pin for each output.
The CLKIN pin can accept either a square wave (LVCMOS)
or clipped sine wave (such as TCXO clipped sine wave
output) as input.
There are 3 different fan-out versions available: 1:3, 1:4 and
1:6.
The 5PB12xx has industry-leading low jitter and extremely
low current consumption, making it ideal for smart mobile
devices.
Applications
• Smart Mobile Handsets
• RF and baseband peripheral clock distribution
• Automotive
Features
• Extremely low operating and standby current consumption
• Low RMS Additive Phase jitter
• Family supports 1.8V to 3.3V power supply voltage:
• For 1.8V supply: 5PB1203, 5PB1204, 5PB1206
• For 2.5V / 3.3V supply: 5PB1213, 5PB1214, 5PB1216
• Three, four, and six outputs with individual Output Enable
pin
• One input
• OE_OSC control pin to enable/disable reference TCXO/XO
• Small 10-pin, 16-pin and 20-pin packages available
• Industrial -40º to +105ºC temperature range

Power supply ground.
Reference input pin. Connect to LVCMOS input or TCXO.
Input Crystal Oscillator enable pin. Follow Enable Function Truth Table.
If all OE pins are low then OE_OSC is low. Otherwise OE_OSC is high,
enabling reference crystal oscillator.
Output Enable pin for CLKOUT1. Active High. Internal 120kΩ pull-down.
Output Enable pin for CLKOUT2. Active High. Internal 120kΩ pull-down.
Output Enable pin for CLKOUT3. Active High. Internal 120kΩ pull-down.
Output Enable pin for CLKOUT4. Active High. Internal 120kΩ pull-down.
Output Enable pin for CLKOUT5. Active High. Internal 120kΩ pull-down.
Output Enable pin for CLKOUT6. Active High. Internal 120kΩ pull-down.
Clock Output 1. Same frequency as CLKIN.
Clock Output 2. Same frequency as CLKIN.
Clock Output 3. Same frequency as CLKIN.
Clock Output 4. Same frequency as CLKIN.
Clock Output 5. Same frequency as CLKIN.
