sp8792 Zarlink Semiconductor, sp8792 Datasheet - Page 3

• Manufacturer Part Number: sp8792
• Description: With On-chip Voltage Regulator
• Manufacturer: Zarlink Semiconductor

+85 C.They divide by 80(40) when control input is in the high
state and by 81(41) when in the low state. An internal voltage
regulator allows operation from a wide range of supply
voltages.
