7 / 50 page – 7 – CXA3106Q External VCO input. Programmable counter test input (controlled by a control register). When using the VCO TTL input, open the Pin 3 VCOH and Pin 4 VCOL PECL inputs. Phase detector disable signal. Active high. When this pin is high, the phase detector output is held. This pin goes to high level when open. (See the HOLD Timing Chart.) Sync input. When using the SYNC TTL input, open the Pin 7 SYNCH and Pin 8 SYNCL PECL inputs. The sync signal can be switched between positive/negative polarity by a control register. Control signal (enable) for setting the internal registers. When SENABLE is low, registers can be written; when high, registers can be read. (See the Control Register Table and Control Timing Chart.) Control signal (clock) for setting the internal registers. When SENABLE is low, SDATA is loaded to the registers at the rising edge of SCLK. When SENABLE is high, the register contents are output from SEROUT at the falling edge of SCLK. (See the Control Register Table and Control Timing Chart.) Control signal (data) for setting the internal registers. (See the Control Register Table and Control Timing Chart.) Programmable counter test input. This pin is normally open status and high. Register contents can be loaded immediately to Programmable counter by setting TLOAD low during the programmable counter test mode. 5 6 9 10 11 12 13 VCO HOLD SYNC SENABLE SCLK SDATA TLOAD TTL TTL TTL TTL TTL TTL TTL I I I I I I I 5 6 9 10 12 13 r/2 r 2r 1.5V IOVCC IOGND 11 Pin No. Symbol I/O Reference voltage level Equivalent circuit Description |
