Notes:
• For optimum VCO linearity (MHz/V), the following resistor ranges are recommended:
2.0 kΩ ≤ RX ≤ 2.7 kΩ (RY = 1.5 kΩ)
1.0 kΩ ≤ RY ≤ 2.0 kΩ (RX = 2.4 kΩ)
• TTL output maximum frequency = 50 MHz
• Simultaneous use of both ECL and TTL outputs are not recommended due to excessive power consumption for the EIAJ Type II
