sp8789 ETC-unknow, sp8789 Datasheet - Page 2

• Manufacturer Part Number: sp8789
• Description: 225mhz ? 20/21 Two Modulus Divider
• Manufacturer: ETC-unknow

counter.lt divides by 20, when the control input is in the high
state and by 21 when in the low state. An internal voltage
regulator allows operation from a wide range of supply
voltages.
