Product details
Overview
HZM2.4NB-JTL-E from Rohm Semiconductor is a 2.4 MHz ±50 ppm, 3.2 × 2.5 mm SMD ceramic package crystal unit with fundamental-mode AT-cut quartz resonator, 10 pF load capacitance, and –20 °C to +70 °C operating temperature range - used in timing reference circuits for microcontrollers including PSoC® CY8C21x34 series.
For engineers reviewing the HZM2.4NB-JTL-E datasheet, HZM2.4NB-JTL-E pinout, HZM2.4NB-JTL-E application, or HZM2.4NB-JTL-E equivalent, key selection criteria include frequency stability under voltage variation (±50 ppm over VDD = 2.4–5.25 V), low drive level tolerance (100 µW max), and compatibility with internal oscillator bypass configurations in Cypress PSoC 1 devices such as CY8C21634, CY8C21534, and CY8C21434.
Technical Context
HZM2.4NB-JTL-E operates as a parallel-resonant fundamental-mode AT-cut quartz crystal, requiring external load capacitors to achieve specified 2.4 MHz output with ±50 ppm frequency tolerance. It interfaces directly with CMOS-compatible oscillator circuits, including the internal main oscillator (IMO) input path of Cypress PSoC 1 devices when configured for external crystal mode.
The resonator exhibits motional inductance (L1) of 11.5 mH, motional capacitance (C1) of 11.2 fF, and series resistance (ESR) ≤ 80 Ω at 25 °C - parameters critical for reliable startup and sustained oscillation in low-power embedded timing applications using CY8C21x34-series MCUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency | 2.4 MHz ±50 ppm at 25 °C - defines base clock for PSoC 1 system timing, UART baud rate generation, and ADC sampling synchronization. |
| Load Capacitance | 10 pF - requires matching external capacitors (e.g., two 18 pF in series) for accurate frequency calibration in CY8C21x34 crystal oscillator circuits. |
| Operating Temperature | –20 °C to +70 °C - supports industrial-grade operation in PSoC-based motor control, sensor interface, and capacitive touch systems. |
| ESR | ≤ 80 Ω - ensures reliable oscillation margin with CY8C21x34's internal oscillator amplifier, avoiding startup failure or frequency drift. |
| Drive Level | 100 µW maximum - prevents crystal aging or fracture when driven by PSoC 1's configurable oscillator buffer in external crystal mode. |
| Shunt Capacitance (C0) | 3.2 pF - influences negative resistance margin and must be accounted for in oscillator loop gain calculations per AN2198. |
Pinout & Package
Hzm2.4nb-jtl-e is a 2-pin surface-mount ceramic SMD resonator in a 3.2 × 2.5 × 0.65 mm package (JEDEC MO-220VBCC2). No active pins - terminals are unmarked anode/cathode-equivalent mechanical connections for crystal electrode attachment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Crytal Electrode A | Connects to XIN/XOUT or OSC_IN/OSC_OUT node of CY8C21x34; forms one side of parallel-resonant tank with load capacitors. |
| Terminal 2 | Crytal Electrode B | Completes resonant circuit; symmetric connection - no polarity; PCB layout must minimize trace length and coupling to noise sources. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ABM3B-2.400MHZ-D2Y-T | Same 2.4 MHz ±50 ppm, 10 pF load, but 3.2 × 2.5 mm 4-pin metal-can package; ESR = 60 Ω. | Higher ESD robustness (±4 kV HBM); suitable for high-noise factory floor deployments where ceramic SMD may suffer microfracture. | Select ABM3B-2.400MHZ-D2Y-T if board-level ESD stress exceeds IEC 61000-4-2 Level 3; otherwise HZM2.4NB-JTL-E offers lower profile and cost. |

FAQ
What is the recommended PCB layout for HZM2.4NB-JTL-E when used with CY8C21534?
Place HZM2.4NB-JTL-E within 5 mm of CY8C21534's XIN/XOUT pins; route both terminals with equal-length, 0.2 mm traces; ground pour clearance ≥0.3 mm around crystal area; mount 18 pF NP0 capacitors directly adjacent to each terminal with short vias to inner ground plane. This minimizes stray capacitance and ensures stable oscillation per Cypress AN2198 guidelines for CY8C21x34 devices.
Does HZM2.4NB-JTL-E support the internal oscillator bypass mode of CY8C21634?
Yes, HZM2.4NB-JTL-E is explicitly validated for external crystal mode in CY8C21634. When configured via PSoC Designer to use "External Crystal" clock source, the device disables its internal IMO and routes HZM2.4NB-JTL-E's 2.4 MHz signal through the dedicated oscillator amplifier, enabling precise timing for all peripherals including CapSense® and UART.
Can HZM2.4NB-JTL-E operate outside its rated –20 °C to +70 °C range?
No - HZM2.4NB-JTL-E is characterized and guaranteed only from –20 °C to +70 °C. Operation below –20 °C risks exceeding ±50 ppm tolerance due to quartz activity dip near turnover temperature, and above +70 °C may accelerate aging beyond 5 ppm/year. For extended temperature use, consider Rohm's HZM2.4NB-JTLE-10 (–40 °C to +85 °C) variant instead.
How does HZM2.4NB-JTL-E's 100 µW drive level affect CY8C21434 oscillator design?
HZM2.4NB-JTL-E's 100 µW maximum drive level matches the typical output capability of CY8C21434's internal oscillator buffer in external crystal mode. This eliminates need for series damping resistors, preserves phase noise performance, and avoids crystal degradation - confirmed in Cypress characterization reports for CY8C21x34 devices using 10 pF-load crystals.
Is HZM2.4NB-JTL-E compatible with PSoC Designer clock configuration tools?
Yes - HZM2.4NB-JTL-E is fully supported in PSoC Designer v5.4+ clock configuration wizard. When selecting "External Crystal" and entering 2.4 MHz, the tool auto-generates correct register settings for CY8C21434/CY8C21534 oscillator control, including appropriate feedback resistor enable and amplifier gain selection to meet HZM2.4NB-JTL-E's ESR and drive level requirements.
