Pin Descriptions Pin Pin No. Type Function Equivalent circuit name LC72121 Xtal • Crystal oscillator element connections (4.5 or 7.2 MHz) XIN XOUT 1 22 1 24 LC72121M LC72121V Local oscillator signal input • FMIN is selected when DVS in the serial data is set to 1. • Input frequency: 10 to 160 MHz • The signal is passed through an internal divide-by-two prescaler and then input to the swallow counter. • The divisor can be set to a value in the range 272 to 65535. Since the internal divide-by-two prescaler is used, the actual divisor will be twice the set value. FMIN 16 17 Local oscillator signal input • AMIN is selected when DVS in the serial data is set to 0. • When SNS in the serial data is set to 1: • Input frequency: 2 to 40 MHz • The signal is input to the swallow counter directly. • The divisor can be set to a value in the range 272 to 65535. The set value becomes the actual divisor. • When SNS in the serial data is set to 0: • Input frequency: 0.5 to 10 MHz • The signal is input to a 12-bit programmable divider directly. • The divisor can be set to a value in the range 4 to 4095. The set value becomes the actual divisor. AMIN 15 16 Continued on next page. |
