Product details
Overview
DS4077L-CCN from Maxim Integrated is a 61.44MHz voltage-controlled crystal oscillator (VCXO) in a 9-pin LGA package, operating from 3.135V to 3.465V with LVCMOS output. It delivers <0.8ps RMS jitter (12kHz–20MHz), ±69ppm absolute pull range, and -125dBc/Hz phase noise at 1kHz offset. Designed for telecom base station reference clocking where low jitter and stable frequency tuning are critical.
For engineers reviewing the DS4077L-CCN datasheet, DS4077L-CCN pinout, DS4077L-CCN application, or DS4077L-CCN equivalent, key selection criteria include VCXO tuning sensitivity (41–164ppm/V), load-dependent frequency stability (±1ppm/pF), aging tolerance (±5ppm first year), and LVCMOS drive capability (VOH ≥ VDD−0.8V, VOL ≤ 0.4V).
Technical Context
The DS4077L-CCN integrates a fundamental-mode quartz crystal with a proprietary oscillator IC, enabling precise analog voltage-controlled frequency adjustment via the VC pin. Its architecture supports wide tuning bandwidth (10kHz VC input bandwidth) and maintains tight frequency accuracy across temperature (±20ppm from +25°C) and supply variation (±11.5ppm over VDD = 3.3V ±5%).
It uses a transfer-molded plastic LGA package with internal varactor-based frequency pulling. The LVCMOS output stage drives 10pF loads with 2ns rise/fall times and 40–60% duty cycle, meeting telecom retiming and clock-data recovery timing budgets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 61.44MHz nominal; fixed frequency per part number, not programmable |
| Jitter (RMS) | <0.8ps over 12kHz–20MHz integration band; meets SONET/SDH OC-192 and 10G Ethernet clocking requirements |
| Phase Noise | <-125dBc/Hz at 1kHz offset; enables low-bit-error-rate data recovery in high-speed serial links |
| Absolute Pull Range | ±69ppm; total frequency deviation achievable across full VC voltage range (0.3V–2.8V) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCXO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si514-A-D-GM | Programmable I²C frequency (not fixed); higher 1.8V supply; 0.5ps RMS jitter | Requires microcontroller configuration; unsuitable for static-frequency, analog-tuned systems | Select DS4077L-CCN when analog VC control, fixed 61.44MHz, and industrial temp range are mandatory |
| AK2-61.440MHZ-E | Fixed 61.44MHz LVCMOS VCXO; ±50ppm APR; 1.2ps RMS jitter; same LGA-9 package footprint | Lower tuning range and higher jitter limit; no guaranteed -40°C startup | Choose DS4077L-CCN for tighter APR, lower jitter, and full industrial temp validation |
Compared with Si514-A-D-GM and AK2-61.440MHZ-E, DS4077L-CCN offers superior analog tuning authority (±69ppm vs. ±50ppm), lower jitter (0.8ps vs. 1.2ps), and guaranteed -40°C operation-critical for carrier-grade infrastructure where analog PLL lock range and thermal margin directly impact system uptime.

FAQ
What is the operating voltage range for DS4077L-CCN?
The DS4077L-CCN operates from 3.135V to 3.465V. This 3.3V nominal supply range ensures compatibility with standard telecom power rails while maintaining specified jitter and phase noise performance. Operation outside this range may cause frequency instability or increased jitter in DS4077L-CCN.
Does DS4077L-CCN support LVDS output?
No, DS4077L-CCN is configured for LVCMOS output only. The LVDS variant for 61.44MHz is the DS4077L-CDN. DS4077L-CCN's pin 4 delivers LVCMOS-compatible logic levels (VOH ≥ VDD−0.8V, VOL ≤ 0.4V) and is not electrically compatible with LVDS receivers.
What is the absolute pull range of DS4077L-CCN?
The DS4077L-CCN has an absolute pull range (APR) of ±69ppm across its full VC voltage range (0.3V to 2.8V). This specification is measured at +25°C with VDD = 3.3V and defines the total frequency deviation achievable under worst-case conditions for DS4077L-CCN.
Can DS4077L-CCN be used in automotive applications?
No, DS4077L-CCN is rated for -40°C to +85°C industrial operation and is not qualified to AEC-Q200 or automotive temperature grades. Its design targets telecom infrastructure-not automotive ECUs-so DS4077L-CCN lacks required automotive reliability testing and qualification documentation.
What is the recommended load capacitance for DS4077L-CCN's LVCMOS output?
The DS4077L-CCN LVCMOS output is characterized for a 10pF load to ground, with rise/fall times and duty cycle specified under that condition. Load capacitance up to 20pF is supported, but frequency deviation increases by up to ±1ppm per pF beyond 10pF, so DS4077L-CCN performance must be verified at actual board-level loading.
