3 / 8 page For Communications Equipment MN6152U Pin Descriptions Pin No. Symbol Function Description 1XIN Crystal oscillator connection pins: 2XOUT XIN =Oscillator circuit input pin; XOUT=Oscillator circuit output pin. 3FV Frequency divider output signal in comparator stage. Phase comparator input monitor. 4VDD Power supply 5DOP Low-pass filter connection pin. Use a passive filter. 6VSS Ground 7LD Phase comparator output pin: "H" level for locked; "L"level for unlocked. 8FIN Frequency divider input pin in comparating stage. 9 CLK Shift register clock input pin. The chip latches data at the rising edge of the CLK signal. 10 DATA Shift register data input pin. The final two bits in the data select the write latch: "11" for R-latch; "01" for N-latch. 11 LE Load enable signal input pin. This is the latch-write-enable signal. It is at "H" level for write. 12 PS Power save control signal input pin. "H" level input starts the frequency divider and places the chip in operational mode. "L" level input places the chip in standby mode, which saves power. The chip switches the internal charge pump output to the H-z state and the loop is opened. 13 FR Reference frequency divider output signal. Phase comparator input monitor. 14 LC Charge pump control signal output pin. When frequency divider operation is stopped, this pin is at "L" level, the internal charge pump output is in the high-impedance state, and the loop is opened. 15 OV Phase comparator output pin for external charge pump. 16 OR |
