Notes:
For optimum VCO linearity (MHz/V), the following resistor ranges are recommended:
2.0 k
RX
2.7 k
(RY = 1.5 k
)
1.0 k
RY
2.0 k
(RX = 2.4 k
)
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
