It's the kind of part you find on a radio tuner board, a signal generator, or a comms module where the local oscillator needs to lock to a crystal or VCXO. ## Active lifecycle — no LTB panic The DS8908BN carries an Active product status. For a repair tech pulling a dead PLL off a board, or a broker filling a BOM line, this is the good news: you're not hunting NOS or paying a premium for a discontinued part. The RoHS non-compliant flag matters if your assembly process requires lead-free solder; if you're reworking a legacy board that was built with tin-lead, it's a non-issue. ## Cross-shopping the CD74HCT7046AE If you're looking for a functional alternative, the CD74HCT7046AE is a phase-locked loop from the 74HCT series, in a through-hole package, with a 4.5 V supply and a -55°C to 125°C temperature range. The DS8908BN is a dedicated frequency synthesizer, not a general-purpose PLL — the CD74HCT7046AE includes a VCO and phase comparator but lacks the programmable divider chain that makes the DS8908BN a synthesizer. For a direct swap, you'd need to check the pinout and the loop-filter design; they're not pin-compatible out of the gate.","metaTitle":"DS8908BN PLL Frequency Synthesizer, Active, Bulk","metaDescription":"DS8908BN PLL frequency synthesizer from * series.
