5 / 17 page 6-bit Digital Step Attenuator 400 to 4000 MHz IDTF1953 Glitch-Free TM Digital Step Attenuator 5 Rev2 April2014 F1953 DATASHEET PARALLEL CONTROL MODE The user has the option of running in one of two parallel modes: Direct Parallel Mode or Latched Parallel Mode. DIRECT-PARALLEL MODE: Direct-parallel mode is selected when VMODE (pin 13) is < VIL and LE (pin 5) is > VIH. In this mode the device will immediately react to any voltage changes to the parallel control pins [pins 1, 15, 16, 17, 19, 20]. Use direct-parallel mode for the fastest settling time. LATCHED-PARALLEL MODE: Latched-parallel mode is selected when VMODE (pin 13) is < VIL and LE (pin 5) is toggled from < VIL to > VIH To utilize latched-parallel mode: Set LE < VIL Adjust pins [1, 15, 16, 17, 19, 20] to the desired attenuation setting. (Note the device will not react to these pins while LE < VIL.) Pull LE > VIH. The device will then transition to the attenuation settings reflected by these pins. When the device is powered up In Latched Parallel Mode [VMODE < VIL and LE < VIL], the attenuation setting defaults to the state defined by the six parallel data pins [pins 1, 15, 16, 17, 19, 20] LATCHED PARALLEL MODE TIMING DIAGRAM: (Note the Timing Spec Intervals in Blue) LATCHED PARALLEL MODE TIMING TABLE: Interval Symbol Description Min Spec Max Spec Units A Serial to Parallel Mode Setup Time 100 nsec B Parallel Data Hold Time 10 nsec C LE minimum pulse width 10 nsec D Parallel Data Setup Time 10 nsec D[5:0] Data Word Latched into Active Register LE VMODE Spec Interval s A D C B |
