PLL1706DBQR Equivalent & Substitute Parts

Part Overview

The PLL1706DBQR is a PLL Multi-Clock Generator IC manufactured by Texas Instruments, designed for clock and timing applications. This surface mount device operates at a maximum frequency of 36.87MHz with a 1:6 input-to-output ratio and supports both CMOS and Crystal inputs. The part is currently in active production status with 4060 units in stock. Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or specific packaging preferences while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the PLL1706DBQR are identified based on strict parametric equivalence. The following electrical and mechanical parameters must remain identical across all substitute parts:

Maximum frequency: 36.87MHz
Input-to-output ratio: 1:6
Input type: CMOS, Crystal
Output type: CMOS
Supply voltage range: 2.7V ~ 3.6V
Operating temperature range: -25°C ~ 85°C
Package type: 20-SSOP (0.154", 3.90mm Width)
Number of circuits: 1
Divider/Multiplier capability: Yes/No configuration
Differential input/output: No/No
RoHS and REACH compliance status
Moisture sensitivity level: 1 (Unlimited)

The PLL1705DBQR and PLL1708DBQR meet all these criteria and are classified as parametric equivalents. Differences in base product numbers and packaging designation (Tape & Reel availability) do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

All three parts—PLL1706DBQR, PLL1705DBQR, and PLL1708DBQR—are active production devices from Texas Instruments with identical electrical specifications and package configurations. Selection between these parts should be based on:

Inventory availability and lead time requirements
Packaging format preference (Tape & Reel availability noted for PLL1708DBQR)
Supply chain sourcing strategy
Compliance requirements (all three meet ROHS3 and REACH standards)

The PLL1708DBQR currently has the highest inventory level at 16,007 units, followed by PLL1706DBQR at 4,060 units, and PLL1705DBQR at 2,916 units. All parts maintain identical moisture sensitivity classification and thermal operating ranges suitable for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can PLL1705DBQR and PLL1708DBQR be used as direct replacements for PLL1706DBQR?

A: Yes. All three parts are parametric equivalents with identical electrical characteristics, frequency specifications, supply voltage ranges, operating temperature ranges, and 20-SSOP package dimensions. Direct substitution is supported without circuit modification.

Q: Are there differences in packaging between these parts?

A: The primary packaging difference is that PLL1708DBQR is available in Tape & Reel (TR) format, while PLL1706DBQR is specified with Tape & Reel packaging and PLL1705DBQR packaging designation is not specified. All three use the same 20-SSOP (0.154", 3.90mm Width) case. Tape & Reel format is suitable for automated assembly processes.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. PLL1706DBQR, PLL1705DBQR, and PLL1708DBQR are all ROHS3 compliant, REACH unaffected, and classified as Moisture Sensitivity Level 1 (Unlimited). All parts carry the same EAR99 export classification and HTSUS code.

Q: What is the input-to-output ratio for these PLL generators?

A: All three parts maintain a 1:6 input-to-output ratio, meaning the output frequency is six times the input frequency at the specified maximum of 36.87MHz.

Q: Are these parts suitable for both CMOS and Crystal input sources?

A: Yes. All three parts accept both CMOS and Crystal input types and provide CMOS output, offering flexibility in clock source selection for timing applications.
