10 / 20 page FREQSET ICN CLOCKSYNC FREQSET IC1 RN TTL LOGIC CLOCKSYNC FREQSET IC2 CLOCKSYNC R1 UC1875-SP SLUSAQ9 – DECEMBER 2011 www.ti.com Synchronizing The Oscillator The CLOCKSYNC pin of the oscillator may be used to synchronize multiple UC1875-SP device by connecting the CLOCKSYNC of each UC1875-SP to the others: Figure 5. ALL ICs will sync to the chip with the fastest local oscillator. R1 and RN may be needed to keep sync pulse narrow due to capacitance on line. R1 and RN may also be needed to properly terminate R(SYNC) line. Syncing to External TTL/CMOS Figure 6. ICs will sync to the fastest chip or TTL clock if it is higher frequency. R1 and RN may be needed to keep sync pulse narrow due to capacitance on line. R1 and RN may also be needed to properly terminate R(SYNC) line. Although the UC1875-SP has a local oscillator frequency, the device will synchronize to the fastest oscillator driving the CLOCKSYNC pin. This arrangement allows the synchronizing connection between ICs to be broken without any local loss of functionality. Synchronizing the device to an external clock signal may be accomplished with a minimum of external circuitry, as shown in Figure 6. Capacitive loading on the CLOCKSYNC pin will increase the clock pulse width, and may adversely effect system performance. Therefore, a resistor to ground from the CLOCKSYNC pin is optional, but may be required to offset capacitive loading on this pin. These resistors are shown in the oscillator schematics as R1, RN. 10 Submit Documentation Feedback Copyright © 2011, Texas Instruments Incorporated Product Folder Link(s): UC1875-SP |
