LMK04828BISQ/NOPB

LMK04828BISQ/NOPB is a Texas Instruments dual-loop PLLatinum jitter cleaner with JESD204B support, in a 9 by 9 mm WQFN-64, for radio, medical-imaging and test systems whose converters need sample clocks cleaner than the system reference. It achieves 88 fs RMS jitter integrated from 12 kHz to 20 MHz (91 fs from 100 Hz to 20 MHz) with a -162.5 dBc/Hz noise floor at 245.76 MHz, and generates up to fourteen differential device clocks plus seven SYSREF outputs from the second PLL — the complete JESD204B clocking set for multi-converter arrays from one chip. Maximum clock output frequency is 3.1 GHz and the second PLL accepts phase-detector rates up to 155 MHz, giving wide freedom in reference selection; the supply is 3.15 V to 3.45 V and the range is -40 to +85 degrees C. Selection advice: the BISQ/NOPB code is the 1,000-piece reel in the NKD package — BISQE (250 pieces) and BISQX (2,000 pieces) are the same device in other reel sizes, so match the suffix to production volume. Device marking is K04828BISQ. Parameters verified against TI documentation for the LMK04828.
