mb15f74uv 11 3. power saving mode (intermittent mode control circuit) the intermittent mode control circuit reduces the pll power consumption. by setting the ps pin low, the device enters into the power saving mode, reducing the current consumption. see the electrical characteristics chart for the specific value. the phase detector output, do, becomes high impedance. for the dual pll, the lock detector, ld, is as shown in the ld output logic table. setting the ps pin high, releases the power saving mode, and the device works normally. the intermittent mode control circuit also ensures a smooth startup when the device returns to normal operation. when the pll is returned to normal operation, the phase comparator output signal is unpredictable. this is because of the unknown relationship between the comparison frequency (fp) and the reference frequency (fr) which can cause a major change in the comparaor output, resulting in a vco frequency jump and an increase in lockup time. to prevent a major vco frequency jump, the intermittent mode control circuit limits the magnitude of the error signal from the phase detector when it returns to normal operation. notes : when power (vcc) is first applied, the device must be in standby mode. ps pin must be set l at power-on. status ps pin normal mode h power saving mode l on off v cc clock data le ps (1) (2) (3) t ps 3 100 ns t v 3 1 m s (1) ps = l (power saving mode) at power-on (2) set serial data at least 1 m s after the power supply becomes stable (v cc 3 2.2 v) .

mb15f74uv 23 n n n n usage precautions (1) v ccrf and v ccif must be equal voltage. even if either rf-pll or if-pll is not used, power must be supplied to v ccrf and v ccif to keep them equal. it is recommended that the non-use pll is controlled by power saving function. (2) to protect against damage by electrostatic discharge, note the following handling precautions : store and transport devices in conductive containers. use properly grounded workstations, tools, and equipment. turn off power before inserting or removing this device into or from a socket. protect leads with conductive sheet, when transporting a board mounted device n n n n ordering information part number package remarks MB15F74UVPVB 18-pin plastic bcc (lcc-18p-m05)
