Characteristics specification 1) IF select specification SELECT pin control enables you to switch IF as below: SELECT = low → fOUT = 129.55 MHz, fR = 50 kHz (P = 16, N = 161, A = 15, R = 256) SELECT = high → fOUT = 178 MHz, fR = 400 kHz (P = 16, N = 27, A = 13, R = 32) 2) Unlock detection and LD output specification LD output is high in a lock mode and low in an unlock mode. Lock signal is outputted in a power save mode. SELECT = high : Detection time is 2.6 µs. About detection accuracy, when a dividing output shifts by ±(78 × 3) ns for fREF = 400 kHz, it generates an unlock output. SELECT = low : Detection time is 20 µs. About detection accuracy, when a dividing output shifts by ±(78 × 3) ns for fREF = 50 kHz, it generates an unlock output. 3) Power save control specification When power save control pin (PS) is high, it is set to an operating mode. When it is low, it is set to power save mode. 4) Analog SW control specification CPSUB is controlled by SW pin. SW.
