SY605JZ - 255-Tap Programmable Delay Line | Microchip
부품 번호: SY605JZ ✓ 활성SY605JZ 개요
A programmable delay line is a timing-control integrated circuit that introduces a digitally selectable interval between an input edge and its corresponding output. It belongs to the clock-and-timing IC hierarchy, where delay lines support calibration, phase alignment, pulse positioning, and clock compensation. Unlike a general-purpose digital delay, this device provides a calibrated tap-based delay structure for fine timing adjustment.
Key features include 255 programmable taps, a 4 ns delay to the first tap, a 40 ns maximum total delay, and 15 ps resolution. Its differential TRIGGER and delay WRITE inputs support robust control-interface design. The less-than-±1-LSB timing-accuracy specification gives engineers a quantified basis for selecting tap values when precise event placement is required.
The SY605JZ is intended for high-speed timing systems where deterministic delay calibration and repeatable retriggering matter. Its 125 MHz retrigger rate allows successive trigger events to be accepted at high repetition rates, while the programmable tap count provides fine control over relative timing. The component is packaged as a 28-LCC J-lead device, with tube packaging identified for SY605JZ and tape-and-reel identified for the SY605JZ TR ordering variant.
Typical uses include clock phasing, pulse-width calibration, time-interval measurement, communication timing alignment, and laboratory or industrial test equipment. Because it is a delay-line IC rather than a general clock generator, designers should evaluate input edge requirements, output timing, control logic, and PCB propagation effects together when defining the external timing budget.
A key design consideration is to preserve controlled edge rates and isolate sensitive timing paths from unnecessary noise. The datasheet-supported TRIGGER and delay WRITE interface should be driven with compatible logic, while power and ground connections should be routed to minimize return-path disturbance. Engineers should also verify all operating conditions against the manufacturer datasheet.
This page consolidates distributor pricing, verified timing specifications, package details, and application guidance. It also distinguishes the SY605JZ from SY605JZ TR as a packaging variant rather than presenting the TR suffix as a different functional device, while clearly identifying where a full pinout or verified drop-in substitute is unavailable in the supplied data.

일반적인 애플리케이션
SY605JZ 적합 용도: 6 애플리케이션s: Clock Phase Alignment, Pulse-Width Calibration, Communication Timing Alignment, Time-Interval Measurement, Industrial Test Equipment, Signal-Integrity Calibration.
Clock Phase Alignment
The SY605JZ is suitable for clock phase alignment because its 255 taps cover a 4 ns to 40 ns adjustment range while providing 15 ps delay resolution. Place the device between a source clock and a receiving circuit, select the required tap through the delay WRITE interface, and preserve clock edge quality across the delay path. The less-than-±1-LSB accuracy specification helps constrain nominal tap error. The main design consideration is fixed input-to-output delay: engineers should include that delay, receiver threshold variation, and board skew in the phase-budget calculation.
추천
Pulse-Width Calibration
The SY605JZ can calibrate pulse position when an instrument or fixture must offset one edge relative to another by a known interval. Its selectable 4 ns to 40 ns range and 15 ps resolution provide enough control granularity for fine timing correction, while the true 125 MHz retrigger rate supports rapidly repeated measurements. Use the differential TRIGGER and delay WRITE controls according to the datasheet and measure the complete channel, including comparator, logic, and propagation delay. Calibration data should be stored if board or temperature variation materially affects the chosen tap.
추천
Communication Timing Alignment
The SY605JZ fits communication test and signal-conditioning systems that require a calibrated variable delay rather than a fixed passive delay line. A 255-tap architecture and 15 ps resolution allow the receiver timing window to be swept around the desired decision point, while the 125 MHz retrigger rate supports repetitive data patterns. Differential control inputs can reduce sensitivity to common-mode noise when implemented exactly as specified. Designers should budget connector, cable, logic-device, and PCB delay separately, and should avoid assuming that 15 ps tap resolution equals 15 ps end-to-end uncertainty.
추천
Time-Interval Measurement
The SY605JZ is useful in time-interval measurement setups that need a programmable reference interval for comparing an event under test with a local timing event. The available 4 ns to 40 ns span and 15 ps increment support fine sweep resolution around a critical threshold. Its high retrigger rate allows repeated launches without depending on a slow one-shot delay network. For defensible measurements, include input comparator delay, jitter, reference-clock uncertainty, and temperature drift in the uncertainty budget, then verify selected taps against a calibrated reference.
추천
Industrial Test Equipment
The SY605JZ can support programmable timing in industrial test equipment that repeatedly stimulates a device under test and evaluates its response at selected offsets. Its 255 taps allow systematic timing sweeps, while 15 ps resolution supports fine placement of the comparison window. The 125 MHz retrigger rate is valuable for high-throughput test sequences, although fixture loading and DUT behavior may impose practical limits. Keep the delay path short, use controlled impedance routing where appropriate, and characterize fixture delay separately from the IC's tap delay.
추천
Signal-Integrity Calibration
The SY605JZ is applicable to signal-integrity calibration systems that require repeatable insertion delay when aligning a probe, fixture, or receiver. Its programmable 4 ns to 40 ns span and 15 ps tap increment let a calibration routine search for the reference crossing point and record the corresponding setting. Differential TRIGGER and delay WRITE inputs support controlled interface implementation when the surrounding logic is compatible. The device does not correct channel distortion by itself, so use it to establish timing alignment before applying channel compensation or waveform processing.

설계 노트
Treat the complete timing path as a delay budget. Include the SY605JZ's 4 ns first-tap delay, selected tap increment, input and output propagation, logic-device delay, connector delay, and PCB skew. The 15 ps resolution is a control increment, not an automatic 15 ps end-to-end accuracy guarantee. Calibrate the assembled channel if the target measurement requires tighter absolute timing.
Place the SY605JZ close to the circuit whose edge is being delayed and keep the TRIGGER and delay WRITE routes away from high-current switching nodes. Use a continuous ground reference, minimize loop area, and maintain the intended edge rate through the data sheet's input recommendations. Since differential control behavior is specified, preserve signal pairing and return-path continuity rather than treating the inputs as ordinary single-ended switches.
Do not mistake SY605JZ TR for a different silicon function; the verified difference is tube versus tape-and-reel ordering. Also avoid assuming that the 4 ns to 40 ns range is selectable continuously: the device provides 255 discrete taps at 15 ps resolution. Confirm the control-code format, power rails, and electrical limits from the manufacturer datasheet before writing firmware or laying out the board.
