Notes
1. One band switch buffer ON with 40 mA.
2. One buffer ON, Io = 40 mA; two buffers ON, maximum sum of Io = 50 mA.
3. The power dissipation is calculated as follows:
PD = VCC1 × ICC1 + VCC2 × ( ICC2 Io) + Io × VCE (satPNP) + ( V33 2) 2 27 k

The device is a single-chip PLL frequency synthesizer designed for TV and VCR tuning systems.

The circuit consists of a divide-by-eight prescaler with its own preamplifier, a 15-bit programmable divider, a crystal oscillator and its programmable reference divider and a phase/frequency detector combined with a charge-pump which drives the tuning amplifier and the 33 V output.

Four high-current PNP band switch buffers are provided for band switching. Two PNP buffers can be switched on simultaneously. The sum of the collector currents is limited to 50 mA.
