The MC145157–2 has a fully programmable 14–bit reference counter, as well

as a fully programmable ÷ N counter. The counters are programmed serially

through a common data input and latched into the appropriate counter latch,

according to the last data bit (control bit) entered.

The MC145157–2 is an improved–performance drop–in replacement for the

MC145157–1. Power consumption has decreased and ESD and latch–up

performance have improved.

• Operating Temperature Range: – 40 to 85°C

• Low Power Consumption Through Use of CMOS Technology

• 3.0 to 9.0 V Supply Range

• Fully Programmable Reference and ÷ N Counters

• ÷ R Range = 3 to 16383

• ÷ N Range = 3 to 16383

• fV and fR Outputs

• Lock Detect Signal

• Compatible with the Serial Peripheral Interface (SPI) on CMOS MCUs

• “Linearized” Digital Phase Detector

• Single–Ended (Three–State) or Double–Ended Phase Detector Outputs

• Chip Complexity: 6504 FETs or 1626 Equivalent Gates
