Key Parameters

Substitute Part Grouping Explanation

Substitution of the PLL1700E/2K is determined by strict equivalence across the following critical parameters:

• Functional Type: PLL Multi-Clock Generator with identical circuit count (1)
• Frequency Specification: Maximum frequency of 36.87MHz
• Signal Interface: TTL input with CMOS output
• Clock Ratio: 1:6 input-to-output ratio
• Supply Voltage: Dual voltage operation (3.3V, 5V)
• Operating Temperature Range: -25°C to 85°C
• Package Specification: 20-SSOP surface mount package with identical physical dimensions
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The PLL1700EG/2K meets all these parameters and is classified as a parametric equivalent to the PLL1700E/2K.

Parameter Comparison

Engineering Selection Recommendations

Both the PLL1700E/2K and PLL1700EG/2K are obsolete products from Texas Instruments. Selection between these parts is based on availability and compliance requirements. Both components maintain ROHS3 compliance and identical MSL Level 1 ratings, ensuring equivalent environmental and regulatory standing. The parametric equivalence across all electrical and mechanical specifications permits direct substitution in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the PLL1700EG/2K replace the PLL1700E/2K in existing designs?

A: Yes. The PLL1700EG/2K is a parametric equivalent with identical electrical specifications, frequency range, signal interface, supply voltage requirements, operating temperature range, and 20-SSOP package dimensions.

Q: Are there any package or pinout differences between these parts?

A: No. Both components use the 20-SSOP surface mount package with identical physical dimensions (0.209" × 5.30mm width). Pinout and package footprint are equivalent.

Q: What is the significance of the product status being obsolete?

A: Obsolete status indicates these components are no longer manufactured by Texas Instruments. Procurement must rely on existing inventory from authorized distributors. Both parts share this status, so neither offers a path to current production components.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PLL1700E/2K and PLL1700EG/2K are ROHS3 compliant with MSL Level 1 ratings, indicating equivalent environmental and regulatory compliance.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: PLL Multi-Clock Generator type, 36.87MHz maximum frequency, TTL input with CMOS output, 1:6 input-to-output ratio, 3.3V/5V dual supply voltage, -25°C to 85°C operating temperature, and 20-SSOP package specification.
