CDTA-type High-speed Tapped Delay Lines

Features

• This high-speed Tapped Delay Line can be used as either a Tapped Output or Tapped Input type Delay Line.
• Because we have developed this component to be used for Tapped In/Output for 70%, 80%, 90% or 100% of the total Delay Time; and, by reversing the In/Output orientation of the In/Out termination, for 10%、20%、30% and 100%, you can select the desired Delay Time in 10% steps.
• When using as a Tapped Output Delay Line, as indicated in Application Example 1, with either Input 50Ω/Output 50Ω, or Input 100Ω/Output 100Ω, you can apply over 5ｋΩ load connections on any of the 4 outputs.
• When using as a Tapped Input Delay Line, as indicated in Application Example 2, by matching the In/Out terminal impedance to 100Ω, with Input 50Ω/Output 100Ω the device can be used as a Variable Delay Line. Because this Tapped device can use a 100Ω line, high-speed operation is maintained.
• In the future, we are planning the release of 25%, 50%, 75% mid-range Output Tapped Delay Lines.
• Samples will be ready: 2009/4Q

  Package Dimensions and Pin Configuration (Provisional) Unit:mm(inch)

  Soldering Conditions Reflow Soldering Maximum Reflow Cycles：2 MSL Levels are not guaranteed. Baking is recommended prior to reflow. Baking Conditions：120°C, 24 hours; or 80°C, 100 hours However, as baking of Tape & Reel packaging is not possible, we recommend transferring to trays prior to baking.

  Soldering Iron：350°C, under 5 seconds

  Application Examples (1) Tapped Output Delay Line For Tapped Output, please apply over 5kΩ load. When connecting multiple taps, the Passband will decrease when compared to a single connection. (Please see Note (1).)
  5pin Input：Output Signal Delay Time

  (2) Tapped Input Delay Line For 50Ω In/Output applications, this connection example is not recommended.（Please see Note (3).）
  5pin Output Signal Delay Time
  	1pin Input：100% 2pin Input：90% 3pin Input：80% 4pin Input：70%
  1pin Output Signal Delay Time
  	2pin Input：10% 3pin Input：20% 4pin Input：30% 5pin Input：100%

  Notes (1)When using as a Tapped Output Delay Line, please apply over 5kΩ load to the Tapped Output connection. When making multiple Tapped connections, please note that the Passband will be approx 40% reduced when compared to a single connection. (2)When using as a Tapped Input Delay Line, because the Input Impedance will be reduced to approx 1/2 of the Intrinsic Impedance of the Delay Line, Input and Output Impedances cannot both be 50Ω. (3)For 50Ω In/Output applications, when using a Tapped Input Delay Line, the Input Impedance will become 25Ω requiring an IC to drive the Delay Line. This is not recommended.

  RoHS Compliance Status 1. Compliance Status RoHS-compliant（Pb85%+ High-temperature solder is used internally. RoHS exemption 7a is applied.） 2. Terminal Plating Sn coating
