Serial input PLL frequency synthesizer NIPPON PRECISION CIRCUITS-1 NIPPON PRECISION CIRCUITS INC. OVERVIEW The SM5158A is a serial data programma- ble PLL Frequency Synthesizer LSI fabricated in NPC's proprietary Molybdenum-gate CMOS technology. Ratios of reference frequency divider and input frequency divider can be independently set.

FEATURES

• Up to 200MHz input frequency (VDD=4.5V) - Up to 35MHz reference frequency (VDD=4.5V) - 5 to 65535 programmable reference frequency divider ratio - 1056 to 65535 programmable input frequency divider ratio - Lock detector - Either Active or Passive filter can be externally used. - 16-pin plastic DIP and 16-pin S-SOP - Molybdenum gate CMOS structure PIN OUT 16-pin SSOP 16-pin DIP 158A OR OV TEST FR DOA LE DATA CLK XIN XOUT FV VDD DOP VSS LD FIN 8 9 SM158AP OR OV TEST FR DOA LE DATA CLK XIN XOUT FV VDD DOP VSS LD FIN 8 9

Final bit(17th bit) is assigned to the control bit. Data are written into shift register at the ris- ing edge of the CLK signal. When LE is HIGH,data is transferred from the shift register to either the latch of refer- ence divider or input divider. Thus data must be written on the shift register while LE is remaining LOW . While all bits of the N latch to are "0", the N counter will be disabled, DOA, DOP are floating,and the supply current will be decreased. While all bits of the R latch are "O", oscilla- tor will be disabled. While all bits of R and N latches are "0", sup- ply current decreases to 10uA or less. CONTROL LSB MSB
