Cautions for use • Set the variable L (between pins 9 and 10) of RFVCO so that the RF output frequency becomes 67.25MHz when 2.7 V is applied to V12 (pin 12) in the US4ch mode for the US specifications, 97.25MHz when 2.6V is applied to V12 (pin 12) in the JPN2ch mode for the JPN specifications, and 211.25MHz when 2.5V is applied to V12 (pin 12) in the TWN13ch mode for the TWN specifications. Set the C (pins 9-10) value of RF VCO, so that the V12 (pin 12) voltage difference ∆V12 CH between US 4CH and US3CH in the US specification and the V12 (pin 12) voltage difference ∆V12CH between JPN2CH and JPN1CH in the JPN specification becomes ∆V12CH≤±0.25V. (This is necessary because the oscillation frequency during free run (without PLL control) of PF VCO differs due to the floating capacity of pattern.) • Handle pins 9 and 10 with care to prevent electrostatic breakdown because their high frequency characteristics are extremely important.
