Electrical Parameters (Must Match):

• Maximum frequency: 1.536GHz
• Input signal types: LVCMOS, LVDS, LVPECL
• Output signal types: LVCMOS, LVDS, LVPECL
• Input:Output ratio: 2:14
• Differential input and output capability: Yes/Yes
• Supply voltage range: 3.15V ~ 3.45V
• Operating temperature range: -40°C ~ 85°C
• PLL functionality: Yes

Mechanical Parameters (Must Match):

• Package type: 64-WFQFN Exposed Pad
• Supplier device package: 64-WQFN (9x9)
• Mounting type: Surface Mount

Compliance Parameters:

• RoHS3 Compliant

Substitute parts differ only in packaging format (Cut Tape vs. Tape & Reel) or manufacturer designation, while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed maintain active product status and are suitable for direct substitution based on electrical and mechanical parameter equivalence. Selection between these parts should be based on the following factors:

Packaging Format: The LMK04808BISQE/NOPB and LMK04806BISQE/NOPB are supplied in Cut Tape (CT) & Digi-Reel® format, while the LMK04803BISQ/NOPB is supplied in Tape & Reel (TR) format. The LMK04808BISQ/NOPB is also available in Cut Tape & Digi-Reel® format. Packaging selection depends on assembly line requirements and order quantity.

Compliance Certification: The LMK04808BISQE/NOPB, LMK04803BISQ/NOPB, and LMK04808BISQ/NOPB carry explicit ROHS3 Compliant and MSL 3 (168 Hours) certifications. The LMK04806BISQE/NOPB does not specify these certifications in the provided data.

Inventory Availability: The LMK04808BISQ/NOPB offers the highest inventory level at 3361 units, followed by the LMK04808BISQE/NOPB at 2080 units, LMK04806BISQE/NOPB at 1406 units, and LMK04803BISQ/NOPB at 1120 units.

Frequently Asked Questions (FAQ)

Q: Can the LMK04803BISQ/NOPB replace the LMK04808BISQE/NOPB in my application?

A: Yes. Both parts are electrically and mechanically equivalent jitter cleaner ICs with identical frequency specifications (1.536GHz), signal type support (LVCMOS, LVDS, LVPECL), input:output ratio (2:14), supply voltage (3.15V ~ 3.45V), operating temperature range (-40°C ~ 85°C), and package type (64-WFQFN Exposed Pad, 64-WQFN 9x9). The primary difference is packaging format: LMK04803BISQ/NOPB uses Tape & Reel (TR) while LMK04808BISQE/NOPB uses Cut Tape (CT) & Digi-Reel®.

Q: What is the difference between LMK04808BISQE/NOPB and LMK04808BISQ/NOPB?

A: Both parts are manufactured by Texas Instruments with identical electrical specifications and package type (64-WFQFN Exposed Pad). The difference lies in packaging format: LMK04808BISQE/NOPB is supplied in Cut Tape (CT) & Digi-Reel® format with 2080 units in stock, while LMK04808BISQ/NOPB is also supplied in Cut Tape (CT) & Digi-Reel® format with 3361 units in stock. Both carry ROHS3 Compliant and MSL 3 (168 Hours) certifications.

Q: Is the LMK04806BISQE/NOPB a suitable substitute?

A: The LMK04806BISQE/NOPB is electrically and mechanically equivalent to the LMK04808BISQE/NOPB across all specified parameters: frequency (1.536GHz), signal types (LVCMOS, LVDS, LVPECL), input:output ratio (2:14), supply voltage (3.15V ~ 3.45V), operating temperature (-40°C ~ 85°C), and package type (64-WFQFN Exposed Pad, 64-WQFN 9x9). However, the LMK04806BISQE/NOPB is manufactured by National Semiconductor, and RoHS and MSL certifications are not specified in the provided data.

Q: What are the critical parameters that determine substitutability?

A: Substitutability is determined by matching the following parameters: maximum frequency (1.536GHz), input and output signal types (LVCMOS, LVDS, LVPECL), input:output ratio (2:14), differential input and output capability (Yes/Yes), supply voltage range (3.15V ~ 3.45V), operating temperature range (-40°C ~ 85°C), package type (64-WFQFN Exposed Pad), and supplier device package (64-WQFN 9x9). All listed substitute parts meet these criteria.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Cut Tape, Tape & Reel, or Digi-Reel®) affects only the physical delivery and handling method, not electrical performance or functional characteristics. All substitute parts deliver identical electrical functionality regardless of packaging format.

Q: Are all substitute parts RoHS compliant?

A: The LMK04808BISQE/NOPB, LMK04803BISQ/NOPB, and LMK04808BISQ/NOPB are explicitly ROHS3 Compliant. The LMK04806BISQE/NOPB does not specify RoHS compliance status in the provided data.
