| CA3318E CA3318E PDF Programming of multiple CA3318E in parallel with different data is also easily accomplished by using the Program Inhibit Mode. Except for CE , all like inputs of the parallel CA3318E may be common. A TTL low-level program pulse applied to an CA3318E CE input with OE /VPP = 12.75 0.25V will program that CA3318E. A high-level CE input inhibits the other CA3318E from being programmed. CA3318E Datasheet OSC: The fixed frequency PWM in the UCC3305 oper- ates at the frequency programmed by the OSC pin. Typically, a a 200pF capacitor from OSC to GND pro- grams the PWM frequency at 100kHz. In addition, this programs the charge pump at 50kHz and the QOUT and QOUT signals at 192Hz. The actual oscillator frequency is a function of both the capacitor from OSC to GND and the resistor from ISET to GND.

The µPA1812 features a low on-state resistance and excellent switching characteristics, and is suitable for applications such as power switch of portable machine and so on. The SEL input selects between the phase-detect and frequency-detect circuits. When the PLL drifts out of lock, taking SEL low reverses the drift by switching in the frequency-detect circuit. Connecting the LOCK output directly to the SEL input should ensure that frequency lock is maintained in the absence of data. It is recommended, however, that a low-pass filter be added between LOCK and SEL to allow for orderly transitions between these circuits. Once the PLL frequency is within 500 PPM of the reference, the LOCK output returns high. As the SEL input goes high, the phase-detect circuit again maintains lock to the incoming NRZ data. |
