No Preview Available ! I C R O ADVANCE C LOC K INFORMATION Communications MK2042-01 Clock Monitor Description The MK2042-01 is designed to switch between two clock sources. The switching can be externally controlled by an input pin or configured to switch automatically if the primary input clock stops. The part also provides clock detection by reporting when the primary input clock has stopped. The MK2042-01 is optimized for use with our MK2049 family of Communication Clock Synthesizers. When used together, the MK2042-01 and MK2049 provide a complete system for switching to an alternate source when the primary clock is lost, or for maintaining a stable frequency on the MK2049 output. For switching between clock sources with no output glitches or short pulses, use the ICS580 or ICS581 multiplexers. Features • Packaged in 16 pin SOIC • User controlled or automatic switching • Clock detect feature • Does not add jitter or phase noise to the clock • Ideal for systems with backup or redundant clocks • Selectable timeouts for clock loss detection • Accepts input frequencies from 0 Hz to 160 MHz • Works with all MK2049-xx to provide enhanced operation • 3.3 V or 5 V operation Block Diagram VDD GND SELB OE INB INA REFIN S2:S0 CENTER 3 Clock Loss Detector VDD CLKOUT NO_INA HIGH GND LOW MDS 2042-01 1 Revision 102600 Printed 11/15/00 Integrated Circuit Systems, Inc. • 525 Race Street • San Jose • CA • 95126 • (408)295-9800tel• www.icst.com 1 page I C R O ADVANCE C LOC K INFORMATION Communications MK2042-01 Clock Monitor VDD S0 S1 S2 INB INA GND SELB REFIN OE VDD CLKOUT NO_INA HIGH LOW GND CENTER 0.01µF 10 kΩ 10 kΩ 8 kHz clock from network FS1 FS0 X2 RES X1 CAP2 VDD GND FCAP CAP1 VDD VDD GND GND CLK ICLK CLK/2 FS3 8K FS2 (Not all connections for MK2049-34 are shown.)
